    "abstract": "We show that the proton and pion transverse momentum distributions measured\nat RHIC for all collision centralities for pions and most of the collision\ncentralities for protons, can be simultaneously described in terms of a thermal\nmodel with common values for the radial flow and temperature, when accounting\nfor the finite size of the interaction region at the time of decoupling. We\nshow that this description is obtained in terms of a simple scaling law of the\nsize of the interaction region with the number of participants in the\ncollision. The behavior of the proton to pion ratio at mid-rapidity can also be\nunderstood as a consequence of the strength of the radial flow and system size\nreached at RHIC energies.",
