DESCRIPTION:Speakers: Olga Shaposhnikova ()\nWe present an extended analys
 is of the transverse energy density ⟨dE_T/dy⟩ at midratpiidty and rele
 vant  values of multiplicity density ⟨dN/dy⟩  and mean transverse mome
 nta ⟨p_T⟩  for identified strange particles produced in the most centr
 al A+A collisions at high energies. The study is based on published experi
 mental data on transverse momentum distributions and particle yields obtai
 ned in Au+Au\, Pb+Pb\, and Xe+Xe collisions in the energy range √(S_NN) 
 from 39 GeV  to  5.44 TeV . \n         Particular attention is paid to the
  quantities entering the calculation of ⟨dE_T/dy⟩: the particle rapidi
 ty density ⟨dN/dy⟩ and the mean transverse momentum ⟨p_T⟩ measured
  at midrapidity . We investigate their dependence on the collision energy 
 √(S_NN )  for different strange-particle species and compare the power-l
 aw fits of the corresponding excitation functions.\nThe obtained energy de
 pendences of ⟨dN/dy⟩\, ⟨p_T⟩\, and ⟨dE_T/dy⟩ are analyzed to t
 est the hypothesis of a common production mechanism for particles with dif
 ferent strange-quark content. The results are discussed within the Multipo
 meron exchange model and the Bjorken approach to energy density estimation
  in relativistic heavy-ion collisions.\nThe authors acknowledge Saint-Pete
