System-size dependence of charged-particle suppression in ultrarelativistic nucleus-nucleus collisions

Andrey V. Belyaev, Arzunik Gevorgyan, A Hayrapetyan, A. Tumasyan et autres

High-energy partons lose energy while propagating through the hot, strongly interacting medium produced in ultrarelativistic nucleus-nucleus collisions, leading to a suppression of particle production at high transverse momentum (p(T)). The dependence of this energy loss on the size of the colliding nuclear …
