The data were recorded with the CMS detector in 2018 and correspond to an integrated luminosity of 1.7 nb(-1). The measurement is performed in the rapidity and transverse momentum ranges vertical bar y vertical bar < 1.6 and 15 < p(T) < 50 GeV/c. The significance of the inclusive X(3872) signal is 4.2 standard deviations. The prompt X(3872) to psi 2S yield ratio is found to be rho(Pb-Pb) = 1.08 +/- 0.49(stat) +/- 0.52(syst), to be compared with typical values of 0.1 for pp collisions.

The Z boson constrains the initial energy and direction of the associated parton. In heavy ion events, azimuthal angular distributions of charged hadrons with respect to the direction of a Z boson are sensitive to modifications of the in-medium parton shower and medium response. compared to reference data from pp interactions, the results for central Pb-Pb collisions indicate a modification of the angular correlations. The measurements of the fragmentation functions and p(T) spectra of charged particles in Z boson events, which are sensitive to medium modifications of the parton shower longitudinal structure, are also reported. Significant modifications in central Pb-Pb events compared to the pp reference data are also found for these observables.]]> Tue 06 Jun 2023 15:22:25 KRAT ]]> Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001016038 Thu 21 Dec 2023 15:16:45 KRAT ]]> Search for strongly interacting massive particles generating trackless jets in proton–proton collisions at √s = 13 TeV https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001008302 Thu 19 Oct 2023 16:13:44 KRAT ]]> Fragmentation of jets containing a prompt J/ψ meson in PbPb and pp collisions at √sNN = 5.02 TeV https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001002633 Thu 15 Jun 2023 13:27:08 KRAT ]]> Study of dijet events with large rapidity separation in proton-proton collisions at √s = 2.76 TeV https://vital.lib.tsu.ru/vital/access/manager/Repository/koha:001002400 35 GeV and rapidity vertical bar y vertical bar < 4.7.
