Observation of electroweak production of W gamma with two jets in proton-proton collisions at root s=13 TeV
Sirunyan, A. M.; et. al. (2020-12-01)
A first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalanc...
Inclusive search for highly boosted Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at root s=13 TeV
Sirunyan, A. M.; et. al. (2020-12-01)
A search for standard model Higgs bosons (H) produced with transverse momentum (p(T)) greater than 450 GeV and decaying to bottom quark-antiquark pairs (b (b) over bar) is performed using proton-proton collision data colle...
Measurement of single-diffractive dijet production in proton–proton collisions at √s=8Te with the CMS and TOTEM experiments
Sirunyan, A.M.; et. al. (2020-12-01)
© 2020, CERN for the benefit of the CMS and TOTEM collaborations.Measurements are presented of the single-diffractive dijet cross section and the diffractive cross section as a function of the proton fractional momentum lo...
Dependence of inclusive jet production on the anti-k(T) distance parameter in pp collisions at root s=13 TeV
Sirunyan, A. M.; et. al. (2020-12-01)
The dependence of inclusive jet production in proton-proton collisions with a center-of-mass energy of 13 TeV on the distance parameter R of the anti-k(T) algorithm is studied using data corresponding to integrated luminos...
Search for decays of the 125 GeV Higgs boson into a Z boson and a rho or phi meson
Sirunyan, A. M.; et. al. (2020-11-01)
Decays of the 125 GeV Higgs boson into a Z boson and a rho (0)(770) or (1020) meson are searched for using proton-proton collision data collected by the CMS experiment at the LHC at root s = 13 TeV. The analysed data set c...
Studies of Charm Quark Diffusion inside Jets Using Pb-Pb and pp Collisions at root s(NN)=5.02 TeV
Sirunyan, A. M.; et. al. (American Physical Society (APS), 2020-09-01)
The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with p(T)(jet) > 60 GeV/c and D-0 mesons with p(T)(D) > 4 GeV/c in lead-le...
Measurement of t(t)over-bar normalised multi-differential cross sections in pp collisions at root s=13 TeV, and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions
Sirunyan, A. M.; et. al. (2020-07-01)
Normalised multi-differential cross sections for top quark pair (t (t) over bar) production are measured in proton-proton collisions at a centre-of-mass energy of 13 TeV using events containing two oppositely charged lepto...
Measurement of quark- and gluon-like jet fractions using jet charge in PbPb and pp collisions at 5.02 TeV
Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2020-07-01)
The momentum-weighted sum of the electric charges of particles inside a jet, known as jet charge, is sensitive to the electric charge of the particle initiating the parton shower. This paper presents jet charge distributio...
Measurements with silicon photomultipliers of dose-rate effects in the radiation damage of plastic scintillator tiles in the CMS hadron endcap calorimeter
Sirunyan, A. M.; et. al. (IOP Publishing, 2020-06-01)
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 par...
Determination of the strong coupling constant alpha(S)(m(Z)) from measurements of inclusive W-+/- and Z boson production cross sections in proton-proton collisions at root s=7 and 8 TeV
Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2020-06-01)
Twelve measurements of inclusive cross sections of W-+/- and Z boson production, performed in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, are compared with perturbative quantum chromodynamics calcul...
