Resumo: The dynamical entropy of dense gluonic states in proton-proton collisions at high energies is studied by using phenomenological models for the unintegrated gluon distribution. The corresponding transverse momentum probability distributions are evaluated in terms of rapidity. The dynamical entropy density is obtained in the rapidity range relevant for the collisions at the Large Hadron Collider. The total entropy density for the dense system is computed as a function of the rapidity evolution ΔY ¼ Y − Y0 given an initial rapidity Y0. The theoretical uncertainties are investigated, and a comparison with related approaches in literature is done.
