A search for Kaluza-Klein excited vector boson resonances, ${W}_{\mathrm{KK}}$, decaying in cascade to three $W$ bosons via a scalar radion $R$, ${W}_{\mathrm{KK}}\ensuremath{\rightarrow}WR\ensuremath{\rightarrow}WWW$, in a final state containing two or three massive jets is presented. The search is performed with $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ …

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 …

The polarizations of promptly produced ${\ensuremath{\chi}}_{c1}$ and ${\ensuremath{\chi}}_{c2}$ mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$. The ${\ensuremath{\chi}}_{c}$ states are reconstructed via their radiative decays ${\ensuremath{\chi}}_{c}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\gamma}$, with the photons being …

The azimuthal anisotropy Fourier coefficients (v_{n}) in 8.16 TeV p+Pb data are extracted via long-range two-particle correlations as a function of the event multiplicity and compared to corresponding results in pp and PbPb collisions. Using a four-particle cumulant technique, v_{n} correlations are …
