Multiplicity dependence of K*(892)(0) and phi(1020) production in pp collisions at root s=13 TeV

Popis výsledku v původním jazyce

The striking similarities that have been observed between high-multiplicity proton-proton (pp) collisions and heavy-ion collisions can be explored through multiplicity-differential measurements of identified hadrons in pp collisions. With these measurements, it is possible to study mechanisms such as collective flow that determine the shapes of hadron transverse momentum (p(T)) spectra, to search for possible modifications of the yields of short-lived hadronic resonances due to scattering effects in an extended hadron-gas phase, and to investigate different explanations provided by phenomenological models for enhancement of strangeness production with increasing multiplicity. In this paper, these topics are addressed through measurements of the K* (892)(0) and phi(1020) mesons at midrapidity in pp collisions at root s = 13 TeV as a function of the charged-particle multiplicity. The results include the p(T) spectra, p(T)-integrated yields, mean transverse momenta, and the ratios of the yields of these resonances to those of longer-lived hadrons. Comparisons with results from other collision systems and energies, as well as predictions from phenomenological models, are also discussed.
