Search for long-lived particles using delayed photons in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2019-12-09)
A search for long-lived particles decaying to photons and weakly interacting particles, using protonproton collision data at root s = 13 TeV collected by the CMS experiment in 2016-2017 is presented. The data set corresponds ...
Search for new particles decaying to a jet and an emerging jet
(Springer Nature, 2019-02-26)
A search is performed for events consistent with the pair production of a new heavy particle that acts as a mediator between a dark sector and normal matter, and that decays to a light quark and a new fermion called a dark ...
Measurements of tt¯ differential cross sections in proton-proton collisions at s√=13 TeV using events containing two leptons
(Springer Nature, 2019-02-22)
Measurements of differential top quark pair t (t) over bar cross sections using events produced in proton-proton collisions at a centre-of-mass energy of 13 TeV containing two oppositely charged leptons are presented. The ...
Measurement of the tt¯ production cross section, the top quark mass, and the strong coupling constant using dilepton events in pp collisions at s√ = 13TeV
(Springer Nature, 2019-04-29)
A measurement of the top quark-antiquark pair production cross section sigma(t (t) over bar) in proton-proton collisions at a centre-of-mass energy of 13 TeV is presented. The data correspond to an integrated luminosity ...
Measurements of t¯tH production and the CP structure of the Yukawa interaction between the Higgs Boson and top quark in the diphoton decay channel
(American Physical Society, 2020-08-05)
The first observation of the (tt) over barH process in a single Higgs boson decay channel with the full reconstruction of the final state (H -> gamma gamma) is presented, with a significance of 6.6 standard deviations ...
Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-11)
A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a ...
Search for top squarks decaying via four-body or chargino-mediated modes in single-lepton final states in proton-proton collisions at √s=13 TeV
(Springer Nature, 2018-09)
A search for the pair production of the lightest supersymmetric partner of the top quark ((t) over tilde (1)) is presented. The search focuses on a compressed scenario where the mass difference between the top squark and ...
A measurement of the Higgs boson mass in the diphoton decay channel
(Springer Nature, 2020-06-10)
A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9 fb(-1) of proton-proton collision data collected during the 2016 LHC running period, with the CMS ...
Study of double parton scattering using W+2-jet events in proton-proton collisions at root s=7 TeV
(Elsevier, 2014-03)
Double parton scattering is investigated in proton-proton collisions at = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated ...
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 ...
