Measurement of the CP-violating phase ϕs in the Bs 0→J/ψϕ(1020)→μ+μ−K+K− channel in proton-proton collisions at s=13TeV
(Physics Letters B, 2021)
The CP -violating weak phase ϕs and the decay width difference ΔΓs between the light and heavy Bs0 mass eigenstates are measured with the CMS detector at the LHC in a sample of 48500reconstructed Bs0→J/ψϕ(1020)→μ+μ−K+K− ...
Studies of charm and beauty hadron long-range correlations in pp and pPb collisions at LHC energies
(Physics Letters B, 2021)
Measurements of the second Fourier harmonic coefficient (v2) of the azimuthal distributions of prompt and nonprompt D$^{0}$ mesons produced in pp and pPb collisions are presented. Nonprompt D$^{0}$ mesons come from beauty ...
Search for singly and pair-produced leptoquarks coupling to third-generation fermions in proton-proton collisions at s=13 TeV
(Physics Letters B, 2021)
A search for leptoquarks produced singly and in pairs in proton-proton collisions is presented. We consider the leptoquark (LQ) to be a scalar particle of charge −1/3e coupling to a top quark plus a tau lepton (tτ) or a ...
Search for the rare decay of the W boson into a pion and a photon in proton-proton collisions at √s=13 TeV
(Physics Letters B, 2021)
A search is performed for the rare decay W±→π±γ in proton-proton collisions at s=13TeV. Data corresponding to an integrated luminosity of 137fb−1 were collected during 2016 to 2018 with the CMS detector. This analysis ...
Measurement of the azimuthal anisotropy of Υ(1S) and Υ(2S) mesons in PbPb collisions at √sNN=5.02 TeV
(Physics Letters B, 2021)
The second-order Fourier coefficients (v2) characterizing the azimuthal distributions of Υ(1S)and Υ(2S)mesons produced in PbPb collisions at √sNN=5.02 TeV are studied. The Υmesons are reconstructed in their dimuon decay ...
First measurement of the cross section for top quark pair production with additional charm jets using dileptonic final states in pp collisions at s=13TeV
(Physics Letters B, 2021)
The first measurement of the inclusive cross section for top quark pairs (tt‾) produced in association with two additional charm jets is presented. The analysis uses the dileptonic final states of tt‾ events produced in ...
Search for W′ bosons decaying to a top and a bottom quark at s=13TeV in the hadronic final state
(Physics Letters B, 2021)
A search is performed for W′ bosons decaying to a top and a bottom quark in the all-hadronic final state, in proton-proton collisions at a center-of-mass energy of 13TeV. The analyzed data were collected by the CMS experiment ...
