Study of Production of (Anti-)deuteron Observed in Au+Au Collisions at sNN=14.5, 62.4, and 200 GeV

Transverse momentum distributions of deuterons and antideuterons in Au + Au collisions at sNN=14.5, 62.4, and 200 GeV with different centrality are studied in the framework of the multisource thermal model. Transverse momentum spectra are conformably and approximately described by the Tsallis distri...
