| Abstract | |
We extend the numerical analysis of the energy and centrality dependence of particle multiplicities at midrapidity in high-energy p + A and A + A collisions from a running coupling k(T)-factorization formula made in A. Dumitru, A.V. Giannini, M. Luzum, Y. Nara, Phys. Lett. B 784, 417 (2018) by considering two unintegrated gluon distributions that were left out. While a good agreement with the experimental data in A+ A collisions is achieved, improving the description of those observables in p + A collisions calls for a better understanding of the proton unintegrated gluon distribution at larger values of x and also the use of a realistic impact parameter dependence.
