Energy Dependence Of Inelasticity Research Articles

Energy dependence of inelasticity and gluon activity in high-energy reactions

The correlation between inelasticity and cross section is discussed for a sample of theoretical models of multiparticle production which address the question of inelasticity and its energy dependence. In particular, assuming the gluonic origin of the growth of cross section, the two-component valon-gluon model (VGM) is formulated and the energy dependence of inelasticity is derived. It is pointed out that the resultant decrease in inelasticity arises as a consequence of the increase with energy of the abundance of gluonic collisions.

Decreasing inelasticity with energy in pp collisions

The energy dependence of inelasticity in the multiparticle production of high-energy hadronic interactions is studied. The similarity between multiparticle productions in pp (pp) and e+e- collisions leads to a complete picture of a universal hadronization process. Within this framework, the data of charged multiplicity at various collider energies are used to infer average inelasticity. The result shows that inelasticity in pp collisions decreases with increasing energy in the range of square root (s)=5-900GeV. Consequences of the extrapolation of such a decreasing inelasticity to energies 1014-1018 eV as well as other model predictions in a series of cosmic ray experiments are also addressed.

On the energy dependence of inelasticity

We show that when transverse momentum (pseudo) rapidity correlations are correctly taken into account the pion inelasticity remains practically constant in the GeV-TeV energy regions. When extending our calculation to the charged particle inelasticity, we find a slow decrease with energy.

Energy dependence of inelasticity

Fitting the data from UA5 and UA7 by a two-component model, the decreasing trend of inelasticity with energy is shown in Sp pS collider energies.
