Search for new physics in events with a leptonically decaying Z boson and a large transverse momentum imbalance in proton–proton collisions at √s = 13 TeV
(2018)The European Physical Journal CA search for new physics in events with a Z boson produced in association with large missing transverse momentum at the LHC is presented. The search is based on the 2016 data sample of proton-proton collisions recorded with the CMS experiment at s√=13TeV, corresponding to an integrated luminosity of 35.9fb−1. The results of this search are interpreted in terms of a simplified model of dark matter production via spin-0 or spin-1 mediators, ...Journal Article -
Search for pair production of vector-like quarks in the bW(b)over-barW channel from proton-proton collisions at root s=13TeV
(2018)Physics Letters BA search is presented for the production of vector-like quark pairs, T (T) over bar or Y (Y) over bar, with electric charge of 2/3(T) or -4/3(Y), in proton-proton collisions at root s= 13 TeV. The data were collected by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.8 fb(-1). The T and Y quarks are assumed to decay exclusively to a W boson and a b quark. The search is based on events with a single ...Journal Article -
Search for a massive resonance decaying to a pair of Higgs bosons in the four b quark final state in proton–proton collisions at √ s = 13 TeV
(2018)Physics Letters BA search for a massive resonance decaying into a pair of standard model Higgs bosons, in a final state consisting of two b quark–antiquark pairs, is performed. A data sample of proton–proton collisions at a centre-of-mass energy of 13 TeV is used, collected by the CMS experiment at the CERN LHC in 2016, and corresponding to an integrated luminosity of 35.9fb −1. The Higgs bosons are highly Lorentz-boosted and are each reconstructed as a ...Journal Article -
Elliptic Flow of Charm and Strange Hadrons in High-Multiplicity p+Pb Collisions at √sNN=8.16 TeV
(2018)Physical Review LettersThe elliptic azimuthal anisotropy coefficient (v_2) is measured for charm (D0) and strange (K0S, Λ, Ξ−, and Ω−) hadrons, using a data sample of p+Pb collisions collected by the CMS experiment, at a nucleon-nucleon center-of-mass energy of √sNN=8.16 TeV. A significant positive v_2 signal from long-range azimuthal correlations is observed for all particle species in high-multiplicity p+Pb collisions. The measurement represents the first ...Journal Article -

Measurement of differential cross sections for Z boson production in association with jets in proton-proton collisions at √s=13TeV
(2018)The European Physical Journal CThe production of a Z boson, decaying to two charged leptons, in association with jets in proton-proton collisions at a centre-of-mass energy of 13TeV is measured. Data recorded with the CMS detector at the LHC are used that correspond to an integrated luminosity of 2.19fb-1. The cross section is measured as a function of the jet multiplicity and its dependence on the transverse momentum of the Z boson, the jet kinematic variables (transverse ...Journal Article -
Constraints on the chiral magnetic effect using charge-dependent azimuthal correlations in pPb and PbPb collisions at the CERN Large Hadron Collider
(2018)Physical Review CCharge-dependent azimuthal correlations of same- and opposite-sign pairs with respect to the second- and third-order event planes have been measured in pPb collisions at √sNN=8.16TeV and PbPb collisions at 5.02 TeV with the CMS experiment at the LHC. The measurement is motivated by the search for the charge separation phenomenon predicted by the chiral magnetic effect (CME) in heavy ion collisions. Three- and two-particle azimuthal ...Journal Article -
Search for vectorlike light-flavor quark partners in proton-proton collisions at √s =8 TeV
(2018)Physical Review DA search is presented for heavy vectorlike quarks (VLQs) that couple only to light quarks in proton-proton collisions at √s=8 TeV at the LHC. The data were collected by the CMS experiment during 2012 and correspond to an integrated luminosity of 19.7 fb−1. Both single and pair production of VLQs are considered. The single-production search is performed for down-type VLQs (electric charge of magnitude 1/3), while the pair-production ...Journal Article -
Observation of the Higgs boson decay to a pair of tau leptons with the CMS detector
(2018)Physics Letters BA measurement of the H → ττ signal strength is performed using events recorded in proton–proton collisions by the CMS experiment at the LHC in 2016 at a center-of-mass energy of 13 TeV. The data set corresponds to an integrated luminosity of 35.9fb−1. The H → ττ signal is established with a significance of 4.9 standard deviations, to be compared to an expected significance of 4.7 standard deviations. The best fit of the product of the ...Journal Article -
Studies of B∗s2(5840)0 and Bs1(5830)0 mesons including the observation of the B∗s2(5840)0→B0K0S decay in proton-proton collisions at √s=8TeV
