Elliptic anisotropy measurement of the f(980) hadron in proton-lead collisions and evidence for its quark-antiquark composition
CMS Collaboration
Despite the f(980) hadron having been discovered half a century ago, the question about its quark content has not been settled: it might be an ordinary quark-antiquark ($\mathr…
Measurement of light-by-light scattering and the Breit-Wheeler process, and search for axion-like particles in ultraperipheral PbPb collisions at = 5.02 TeV
CMS Collaboration
Measurements of light-by-light scattering (LbL, ) and the Breit-Wheeler process (BW, ) are reported in ultraperipheral PbPb collisi…
Girth and groomed radius of jets recoiling against isolated photons in lead-lead and proton-proton collisions at = 5.02 TeV
CMS Collaboration
This Letter presents the first measurements of the groomed jet radius and the jet girth in events with an isolated photon recoiling against a jet in lead-lead (P…
Multiplicity and transverse momentum dependence of charge-balance functions in pPb and PbPb collisions at LHC energies
CMS Collaboration
Measurements of the charge-dependent two-particle angular correlation function in proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of …
Two-particle Bose-Einstein correlations and their Lévy parameters in PbPb collisions at = 5.02 TeV
CMS Collaboration
Two-particle Bose-Einstein momentum correlation functions are studied for charged-hadron pairs in lead-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_\math…
Higher-order moments of the elliptic flow distribution in PbPb collisions at = 5.02 TeV
CMS Collaboration
The hydrodynamic flow-like behavior of charged hadrons in high-energy lead-lead collisions is studied through multiparticle correlations. The elliptic anisotropy values based on di…
