Study of multiplicity dependence in Charmed Hadrons production in pp collisions at LHC energies

We report the analysis by performing the fitting on the experimental p T spectra of heavy flavour hadrons, including prompt D 0 , D s + , and Λ c + hadrons, in proton-proton collisions at s = 13 TeV at midrapidity ( | y | < 0.5 ), using the thermodynamically consistent Tsallis distribution functi...

Description
Summary:We report the analysis by performing the fitting on the experimental p T spectra of heavy flavour hadrons, including prompt D 0 , D s + , and Λ c + hadrons, in proton-proton collisions at s = 13 TeV at midrapidity ( | y | < 0.5 ), using the thermodynamically consistent Tsallis distribution function. The data for the fitting is taken from the ALICE experiment at LHC. The quality of the Tsallis fits with fixed μ =0 chemical potential has proved to be significantly better than those with fitted μ value. The extracted nonextensivity parameter q values for D 0 and D s + mesons proved to be compatible with those obtained earlier for the charged pions and kaons in high-energy proton-proton collisions. The extracted q values for Λ c + baryons are found to be compatible with those obtained earlier for the protons and antiprotons in high-energy proton-proton collisions. We have confirmed the relation q ( m e s o n s ) > q ( b a r y o n s ) for heavy flavor hadrons, obtained for light hadrons in high-energy pp collisions. The effective Tsallis temperature for the heavy flavor hadrons increases with multiplicity in proton-proton collisions at s = 13 TeV.
