Bautista, I., Dias de Deus, J. and Pajares, C. (2012), "Elliptic flow at RHIC and LHC in the string percolation approach", EUROPEAN PHYSICAL JOURNAL C, 72, 6.
Abstract: The percolation of strings gives a good description of the RHIC
experimental data on the elliptic flow, v(2), and predicted a rise on
the integrated v(2) of the order of 25 % at LHC such as has been
experimentally obtained. We show that the dependence of v(2) on p(T) for
RHIC and LHC energies is approximately the same as has been observed,
for all the centralities. We show the results for different particles
and the dependence of v(2) on the centralities and rapidity.
