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-lead (Pb-Pb) and proton-proton (pp) collisions at …

Abstract Normalised multi-differential cross sections for top quark pair ( $$\hbox {t}{\bar{\hbox {t}}}$$ tt¯ ) production are measured in proton-proton collisions at a centre-of-mass energy of 13 $$\,{\text {TeV}}$$ TeV using events containing two oppositely charged leptons. The analysed data were recorded …

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-next-to-leading (NNLO) orders in perturbative quantum chromodynamics, and the strong coupling evolution at …

Charge-dependent anisotropy Fourier coefficients (${v}_{n}$) of particle azimuthal distributions are measured in $p\mathrm{Pb}$ and $\mathrm{PbPb}$ collisions at $\sqrt{{s}_{{}_{\mathrm{NN}}}}=5.02\phantom{\rule{0.16em}{0ex}}\mathrm{TeV}$ with the CMS detector at the LHC. The normalized difference in the second-order anisotropy coefficients (${v}_{2}$) between positively and negatively charged particles is found …
