Measurements with silicon photomultipliers of dose-rate effects in the radiation damage of plastic scintillator tiles in the CMS hadron endcap calorimeter
(IOP Publishing, 2020-06)
Measurements are presented of the reduction of signal output due to radiation damage for two types of plastic scintillator tiles used in the hadron endcap (HE) calorimeter of the CMS detector. The tiles were exposed to ...
Search for W boson decays to three charged pions
(American Physical Society, 2019-04-18)
For the first time, a search for the rare decay of the W boson to three charged pions has been performed. Proton-proton collision data recorded by the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to ...
Measurements of the pp → WZ inclusive and differential production cross sections and constraints on charged anomalous triple gauge couplings at s√ = 13 TeV
(Springer Nature, 2019-04-18)
The WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy = 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb(-1). The inclusive ...
Identification of heavy, energetic, hadronically decaying particles using machine-learning techniques
(IOP Publishing, 2020-06)
Machine-learning (ML) techniques are explored to identify and classify hadronic decays of highly Lorentz-boosted W/Z/Higgs bosons and top quarks. Techniques without ML have also been evaluated and are included for comparison. ...
Search for long-lived particles decaying into displaced jets in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2019-02-21)
A search for long-lived particles decaying into jets is presented. Data were collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV in 2016, corresponding to an ...

A search is conducted for new physics in final states containing a photon and missing transverse momentum in proton-proton collisions at <mml:msqrt>s</mml:msqrt>=13 TeV, using the data collected in 2016 by the CMS experiment ...
Angular analysis of the decay B + → K + μ + μ − in proton-proton collisions at √s =8 TeV
(American Physical Society, 2018-12-01)
The angular distribution of the flavor-changing neutral current decay B+→K+μ+μ- is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS detector at ...
Event shape variables measured using multijet final states in proton-proton collisions at s√=13 TeV
(Springer Nature, 2018-12-01)
The study of global event shape variables can provide sensitive tests of predictions for multijet production in proton-proton collisions. This paper presents a study of several event shape variables calculated using jet ...
Search for pair-produced resonances each decaying into at least four quarks in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2018-10-05)
This Letter presents the results of a search for pair-produced particles of masses above 100 GeV that each decay into at least four quarks. Using data collected by the CMS experiment at the LHC in 2015-2016, corresponding ...
Search for vector-like quarks in events with two oppositely charged leptons and jets in proton–proton collisions at s√ = 13 TeV
(Springer Nature, 2019-04-26)
A search for the pair production of heavy vector-like partners T and B of the top and bottom quarks has been performed by the CMS experiment at the CERN LHC using proton-proton collisions at . The data sample was collected ...
