Searches for physics beyond the standard model with the MT2 variable in hadronic final states with and without disappearing tracks in proton–proton collisions at √s = 13 TeV
(Springer Nature, 2020-01-03)
Two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance. The results are based on a sample of proton-proton collisions ...
Extraction and validation of a new set of CMS PYTHIA8 tunes from underlying-event measurements
(Springer Nature, 2020-01-03)
New sets of CMS underlying-event parameters ("tunes") are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-ne ...
Measurement of the top quark Yukawa coupling from t¯t kinematic distributions in the lepton + jets final state in proton-proton collisions at √ s = 13 TeV
(American Physical Society, 2019-10-17)
Results are presented for an extraction of the top quark Yukawa coupling from top quark-antiquark (t (t) over bar) kinematic distributions in the lepton plus jets final state in proton-proton collisions, based on data ...
Search for charged Higgs bosons in the H± → τ±ντ decay channel in proton-proton collisions at s√=13 TeV
(Springer Nature, 2019-07-24)
A search is presented for charged Higgs bosons in the H± → τ ± ντ decay mode in the hadronic final state and in final states with an electron or a muon. The search is based on proton-proton collision data recorded by the ...
Search for a light pseudoscalar Higgs boson in the boosted μμττ final state in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2020-08-27)
A search for a light pseudoscalar Higgs boson (a) decaying from the 125 GeV (or a heavier) scalar Higgs boson (H) is performed using the 2016 LHC proton-proton collision data at root s = 13 TeV, corresponding to an integrated ...
Studies of beauty suppression via nonprompt D 0 mesons in Pb-Pb collisions at √s NN = 5.02 TeV
(American Physical Society, 2019-07-09)
The transverse momentum spectra of D-0 mesons from b hadron decays are measured at midrapidity (vertical bar y vertical bar < 1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the ...
Measurement of properties of B 0 s → µ + µ − decays and search for B 0 → µ + µ − with the CMS experiment
(Springer Nature, 2020-04-28)
Results are reported for the B 0s ! + branching fraction and effective lifetime and from a search for the decay B0 ! + . The analysis uses a data sample of proton-proton collisions accumulated by the CMS experiment in 2011, ...
Measurement of the associated production of a Z boson with charm or bottom quark jets in proton-proton collisions at s=13 TeV
(American Physical Society, 2020-08-19)
Ratios of cross sections, sigma(Z + c jets)/sigma(Z + jets), sigma(Z + b jets)/sigma(Z + jets), and sigma(Z + c jets)/sigma(Z + b jets) in the associated production of a Z boson with at least one charm or bottom quark jet ...
Search for dark photons in decays of Higgs bosons produced in association with Z bosons in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2019-10-10)
A search is presented for a Higgs boson that is produced in association with a Z boson and that decays to an undetected particle together with an isolated photon. The search is performed by the CMS Collaboration at the ...
Mixed higher-order anisotropic flow and nonlinear response coefficients of charged particles in PbPb collisions at root √sNN = 2.76 and 5.02 TeV
(Springer Nature, 2020-06-13)
Anisotropies in the initial energy density distribution of the quark-gluon plasma created in high energy heavy ion collisions lead to anisotropies in the azimuthal distributions of the final-state particles known as ...
