Search for the lepton flavor violating decay $\PGt\!\to\!3\PGm$ in proton-proton collisions at $\sqrt{s}=13\TeV$

In the standard model (SM) with massless neutrinos, the three lepton flavor numbers are exactly conserved. The observation of neutrino oscillations not only proves that lepton flavor is not conserved in the neutral sector, but also provides a mechanism, through neutrino loops, for lepton flavor violating (LFV) decays of charged leptons such as $\PGt\!\to\!3\PGm$, albeit with extraordinarily small branching fractions [1, 2, 3]. However, a number of SM extensions predict a much larger $\PGt\!\to\!3\PGm$ branching fraction, including values as high as $10^{-10}$–$10^{-8}$ [4, 5, 6], accessible to current and near-future experiments. The BaBar Collaboration set a limit of $\mathcal{B}(\PGt\!\to\!3\PGm)<5.3\times 10^{-8}$ at 90% confidence level (\CL) [7]. The present best limit of ${<}2.1\times 10^{-8}$ at 90% CL was obtained by the Belle experiment [8]. Searches at the CERN LHC are approaching this sensitivity with 90% \CLupper limits of $4.6\times 10^{-8}$ from LHCb [9] and $38\times 10^{-8}$ from ATLAS [10].

The LHCb and ATLAS results targeted \PGtproduction from heavy-flavor hadron decays and \PWboson decays, respectively. While many more \PGtleptons are produced from heavy-flavor hadron decays, the \PGtleptons from \PWdecays tend to have larger transverse momentum (\pt) and are typically isolated from hadronic activity, providing an experimental signature with much less background. In this paper, we present results from the CMS experiment of the first search for the LFV decay $\PGt\!\to\!3\PGm$ from a combination of the two independent channels (production in \PWboson and heavy-flavor hadron decays). Using both channels, for which CMS has comparable sensitivity, provides the best opportunity for a discovery or the lowest upper limit on the branching fraction. The data were collected at the LHC in 2016 from proton-proton ($\Pp\Pp$) collisions at a center-of-mass energy of 13\TeV, and correspond to an integrated luminosity of 33.2\fbinv. Inclusion of charge-conjugate states is implied throughout this paper.

The central feature of the CMS apparatus is a superconducting solenoid of 6\unitm internal diameter, providing a magnetic field of 3.8\unitT. Within the solenoid volume are a silicon pixel and strip tracker, a lead tungstate crystal electromagnetic calorimeter, and a brass and scintillator hadron calorimeter, each composed of a barrel and two endcap sections. Muons are measured in gas-ionization detectors embedded in the steel flux-return yoke outside the solenoid. Additional forward calorimetry complements the coverage provided by the barrel and endcap detectors. A more detailed description of the CMS detector, together with a definition of the coordinate system used and the relevant kinematic variables, can be found in Ref. [11].

Events of interest are selected using a two-tiered trigger system [12]. The first level (L1), composed of custom hardware processors, uses information from the calorimeters and muon detectors to select events at a rate of around 100\unitkHz within a fixed time interval of less than 4\mus. The second level, known as the high-level trigger, consists of a farm of processors running a version of the full event reconstruction software optimized for fast processing, and reduces the event rate to around 1\unitkHz before data storage.

The particle-flow algorithm [13] aims to reconstruct and identify each individual particle in an event, with an optimized combination of information from the various elements of the CMS detector. In particular, muons are identified by matching tracks in the silicon tracker with tracks in the muon detector and verifying the energy deposited in the calorimeters is consistent with that expected for muons. The muon momentum is obtained from the curvature observed in the silicon tracker and the relative \ptresolution for muons with $\pt<100\GeV$ is 1% in the barrel and 3% in the endcaps [14].

Simulated event samples are used to validate the analysis, measure acceptance and efficiency, and estimate systematic uncertainties. For the analysis of \PGtleptons from \PWboson decays, events were simulated using \MGvATNLO2.5.2 [15, 16] at leading order, assuming a two-Higgs-doublet model that allows for flavor changing neutral currents and LFV processes, interfaced with \PYTHIAfor parton shower and hadronization descriptions. The \PWproduction and decay, as well as the \PGtdecay, are handled by \MGvATNLO. The \ptdistribution of the \PWboson is reweighted to match that obtained from a SM next-to-leading-order $\PW\!\to\!\ell\PGn$ sample produced with \MGvATNLOand interfaced to \PYTHIAfor parton showers and hadronization. For the analysis of \PGtleptons from heavy-flavor hadron decays, events were simulated using \PYTHIA8.226 [17] with the CUETP8M1 tune [18] interfaced with \EVTGEN1.6.0 [19] for particle decays, with the \PGtdecay kinematics determined by phase space, rather than a particular model. All events are passed through the CMS detector simulation based on \GEANTfour [20]. The multiple $\Pp\Pp$ collisions that occur within the same or nearby bunch crossings (pileup) are modeled by including additional minimum bias events generated with \PYTHIAwith a distribution that matches the one observed in data. Simulated events are reconstructed with the same algorithms as used for data, including emulation of the triggers.

The triggers used by this analysis evolved during the data collection period, primarily to cope with increases in the instantaneous luminosity. Most of the data were collected with an L1 trigger requirement of either three muons, two muons with at least one muon having $\pt>10\GeV$, or two muons with both muons having an absolute pseudorapidity of $\abs{\eta}<1.6$. The dimuon L1 triggers also required the two muons to have an absolute pseudorapidity difference $\abs{\Delta\eta}<1.8$. The high-level trigger required three reconstructed charged particles (tracks), of which two must be identified as muons with $\pt>3\GeV$ and the other must have $\pt>1.2\GeV$. The three tracks are fitted to a common vertex and kept if the normalized $\chi^{2}$ of the fit is less than 8; the vertex location is at least 2 times its uncertainty from the beamline; the \ptof the combination ($\pt^{\kern 0.7pt{3\PGm}}$) is greater than 8\GeV; the invariant mass (assuming a muon mass for all tracks) is in the range 1.60–2.02\GeV; and the cosine of the angle in the transverse plane between the three-track momentum vector and the vector from the beamline to the vertex is greater than 0.9. During the first half of 2016, errors in the L1 triggers used by this analysis resulted in a significant loss of efficiency for muons with $\abs{\eta}>1.24$. While this trigger misconfiguration is not modeled by the simulation, it is accounted for by the analysis.

Offline, all combinations of three muons in the event with a combined charge of ${\pm}1$ are considered and a fit to a common vertex is attempted to make a \PGtcandidate. The muons are required to match the ones used in the trigger, and the trigger-level selection criteria are reapplied. If either of the oppositely charged dimuon combinations from the \PGtcandidate has an invariant mass within 20\MeVof the mass of the \Pgoor \Pgfresonances, the candidate is rejected. Events with at least one \PGtcandidate with an invariant mass between 1.6 and 2.0\GeVare kept for analysis by two different algorithms, one optimized for production of \PGtleptons in \PWboson decays and the other optimized for production of \PGtleptons in heavy-flavor hadron decays.

The measurement of the $\PGt\!\to\!3\PGm$ branching fraction for \PGtleptons produced in charm and bottom decays is complicated by uncertainties in the production of heavy-flavor hadrons. These uncertainties are reduced by utilizing the decay $\PsDp\!\to\!\PGf\PGpp\!\to\!\PGmp\PGmm\PGpp$ to normalize the signal yield.

Simulated samples are used to estimate the relative production of \PGtleptons from different sources and to determine the acceptance and efficiency of the signal and normalization modes. Four samples are used to extract the acceptance and efficiency. The first is a sample of $\PsDp\!\to\!\PGtp\PGn$ decays. The second and third samples contain the inclusive $\PBp\!\to\!\PGt+X$ and $\PBz\!\to\!\PGt+X$ decays, respectively. The fourth sample contains $\PsDp\!\to\!\PGf\PGpp\!\to\!\PGmp\PGmm\PGpp$ events. For all samples, the heavy-flavor decays are simulated with \EVTGEN1.6.0, with the $\PGt\!\to\!3\PGm$ decay occurring via phase space. In the first and fourth samples, the \PsDpmesons can be produced by hadronization or from \PQbhadron decays. The acceptance $\mathcal{A}$ is the fraction of events in which all tracks of the \PGtor \PsDpdecay have $\abs{\eta}<2.4$, the muons have $p>2.5\GeV$, and the pion (if present) has $\pt>1\GeV$. The efficiency is the product of the reconstruction and selection efficiency $\epsilon^{\text{reco}}$ and the trigger efficiency $\epsilon^{\text{trig}}$.

The branching fraction $\mathcal{B}(\PGt\!\to\!3\PGm)$ is extracted from a simultaneous unbinned maximum likelihood fit to the trimuon invariant mass distribution (1.6–2\GeV) in the two categories of the \PWboson analysis and the six categories of the heavy-flavor analysis.

For the \PWboson analysis, the signal model is a Gaussian function with fixed mean and width, as determined from fitting the simulated events in the appropriate category. For the heavy-flavor selection, the signal model is a Gaussian plus Crystal Ball function [29] with fixed mean and width, as determined from fitting the simulated events in the appropriate category and modified as described in Section 0.5.3. In all cases, the background model is an exponential function with parameters and normalization determined by the fit.

As can be seen in the trimuon invariant mass plots of Figs. 1 and 2, no evidence for a $\PGt\!\to\!3\PGm$ signal is found. Upper limits on $\mathcal{B}(\PGt\!\to\!3\PGm)$ are determined from a fully frequentist method [31] based on modified profile likelihood test statistics and the \CLscriterion [32, 33]. Systematic uncertainties are incorporated in the analysis via nuisance parameters. Uncertainties are assumed to be uncorrelated between the two channels. A log-normal probability density function is assumed for the nuisance parameters affecting the corrected signal yields. Events from data and simulation that pass the selection criteria of both analyses are removed from the heavy-flavor analysis in the combined fit.

The observed (expected) upper limit at 90% \CLon $\mathcal{B}(\PGt\!\to\!3\PGm)$ using all events is $8.0\times 10^{-8}$ $(6.9\times 10^{-8})$. Fitting the \PWboson and heavy-flavor events separately returns observed (expected) 90% \CLupper limits of $20\times 10^{-8}$ $(13\times 10^{-8})$ and $9.2\times 10^{-8}$ $(10.0\times 10^{-8})$, respectively.

The results of a search for the lepton flavor violating decay $\PGt\!\to\!3\PGm$, using proton-proton collisions with a center-of-mass energy of 13\TeVat the LHC, are presented. The search uses data collected by CMS in 2016, corresponding to an integrated luminosity of 33.2\fbinv, and, for the first time, combines the result of two analyses: one targeting \PGtleptons produced in \PWboson decays and the other using \PGtleptons from heavy-flavor hadron decays. No signal is observed, and the branching fraction $\mathcal{B}(\PGt\!\to\!3\PGm)$ is determined to be less than $8.0\times 10^{-8}$ at 90% confidence level, with an expected upper limit of $6.9\times 10^{-8}$. While the limit obtained in this measurement is still a factor of four away from the current most restrictive one from the Belle experiment [8], we have achieved similar sensitivity to that by BaBar [7] and LHCb [9].
