DESCRIPTION:Speakers: Ms. ESPINOZA PÉREZ\, Alicia Esmeralda (Benemérita 
 Universidad Autónoma de Puebla)\nWe conduct a data-driven analysis of sof
 tened hadron production in pp and AA collisions at LHC energies\, using th
 e string fragmentation model as the baseline for charged-particle producti
 on. We observed that the pT spectrum data reported by the ALICE collaborat
 ion deviate from the produced particles modeled by the fragmentation of co
 lor strings\, behaving as a pT-exponential in the range between 1 and 6 Ge
 V (intermediate pT region). This insight shows that the pT spectrum contai
 ns information on charged-particle production from two sources: fragmentat
 ion of color strings and collective phenomena that redistribute transverse
  momentum and enhance particle production at intermediate pT. We found sca
 ling laws for the contribution of the softened hadrons to the pT spectrum\
 , multiplicity and average pT\, showing that the physical mechanisms produ
 cing softened hadrons have similar origins for all colliding systems\, rev
 ealing a stronger dependence on freeze-out parameters than on system size.
