Predictions on the transverse momentum spectra for charged particle production at LHC-energies from a two component model
Transverse momentum spectra, , of charged hadron
production in -collisions are considered in terms of a recently introduced
two component model. The shapes of the particle distributions vary as a
function of c.m.s. energy in the collision and the measured pseudorapidity
interval. In order to extract predictions on the double-differential
cross-sections of hadron production for future
LHC-measurements the different sets of available experimental data have been
used in this study.Comment: 5 pages, 7 plot
Two components in charged particle production in heavy-ion collisions
Transverse momentum spectra of charged particle production in heavy-ion
collisions are considered in terms of a recently introduced Two Component
parameterization combining exponential ("soft") and power-law ("hard")
functional forms. The charged hadron densities calculated separately for them
are plotted versus number of participating nucleons, . The obtained
dependences are discussed and the possible link between the two component
parameterization introduced by the authors and the two component model
historically used for the case of heavy-ion collisions is established. Next,
the variations of the parameters of the introduced approach with the center of
mass energy and centrality are studied using the available data from RHIC and
LHC experiments. The spectra shapes are found to show universal dependences on
for all investigated collision energies.Comment: a version as to appear in NPB after editorial comment
