Two-particle azimuthal correlations in γp interactions using pPb collisions at sNN=8.16TeV

A. Tumasyan, W. Adam, T. Bergauer, M. Dragicevic et autres

The first measurements of the Fourier coefficients (VnΔ) of the azimuthal distributions of charged hadrons emitted from photon-proton (γp) interactions are presented. The data are extracted from 68.8 nb−1 of ultra-peripheral proton-lead (pPb) collisions at sNN=8.16TeV using the CMS detector. The high …

Measurement of differential cross sections for the production of a $Z$ boson in association with jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

A measurement is presented of the production of Z bosons that decay into two electrons or muons in association with jets, in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded by the CMS Collaboration at the LHC …

Search for W$\gamma$ resonances in proton-proton collisions at $\sqrt{s} =$ 13 TeV using hadronic decays of Lorentz-boosted W bosons

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

A search for W$\gamma$ resonances in the mass range between 0.7 and 6.0 TeV is presented. The W boson is reconstructed via its hadronic decays, with the final-state products forming a single large-radius jet, owing to a high Lorentz boost of the …

Observation of $\mathrm{B^{0}_{s}}$ mesons and measurement of the $\mathrm{B^{0}_{s}}/\mathrm{B^{+}}$ yield ratio in PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV

A. Tumasyan, R. Erbacher, C. A. Carrillo Montoya, W. Carvalho et autres

The $\mathrm{B^{0}_{s}}$ and $\mathrm{B^{+}}$ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity of 1.7 nb$^{-1}$. The mesons …

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

Albert M. Sirunyan, A. Tumasyan, W. Adam, T. Bergauer et autres

The first measurement of the inclusive cross section for top quark pairs ( t t ‾ ) produced in association with two additional charm jets is presented. The analysis uses the dileptonic final states of t t ‾ events produced in proton-proton …

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract This paper presents new sets of parameters (“tunes”) for the underlying-event model of the $${\textsc {herwig}} \,7$$ H E R W I G 7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in $${\textsc {herwig}} …

High precision measurements of Z boson production in PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV

Albert M. Sirunyan, R. Erbacher, C. A. Carrillo Montoya, W. Carvalho et autres

The CMS experiment at the LHC has measured the differential cross sections of Z bosons decaying to pairs of leptons, as functions of transverse momentum and rapidity, in lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measured Z boson …

Albert M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

Abstract A search is presented for supersymmetric partners of the top quark (top squarks) in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from $${\text {b}}$$ b quarks, and missing transverse momentum. The search uses data …

Evidence for X(3872) in PbPb collisions and studies of its prompt production at $\sqrt{s_\mathrm{NN}}=$ 5.02 TeV

Albert M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

The first evidence for X(3872) production in relativistic heavy ion collisions is reported. The X(3872) production is studied in lead-lead (PbPb) collisions at a center-of-mass energy of $\sqrt{s_\mathrm{NN}}=$ 5.02 TeV per nucleon pair, using the decay chain X(3872) $\to$ J$/\psi\, \pi^+\pi^- \to …
