First evidence for mixing-induced violation in B J/(1020) decays in pp collisions at 13 TeV
CMS Collaboration
A novel machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27000 tagged B J/…
Observation of hyperon local polarization in pPb collisions at = 8.16 TeV
CMS Collaboration
The polarization of the and hyperons along the beam direction has been measured in proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 8.…
Probing gluon fluctuations in nuclei with the first energy-dependent measurement of incoherent J/ photoproduction in ultraperipheral PbPb collisions
CMS Collaboration
Incoherent J/ photoproduction in heavy ion ultraperipheral collisions (UPCs) provides a sensitive probe of localized, fluctuating gluonic structures within heavy nuclei. This s…
Observation of the charged-particle multiplicity dependence of in pPb collisions at 8.16 TeV
CMS Collaboration
Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadro…
Evidence for similar collectivity of high transverse momentum particles in pPb and PbPb collisions
CMS Collaboration
Charged hadron elliptic anisotropies () are presented over a wide transverse momentum () range for proton-lead (pPb) and lead-lead (PbPb) collisions at nucleon-nuc…
