UNIVERSAL SUPPRESSION OF HIGH-p(T) HADRONS IN HEAVY-ION COLLISIONS
Original language description
Data from the ALICE experiment demonstrate universality of suppression of different hadrons produced with high p(T) in heavy-ion collisions (HICs) at the Large Hadron Collider (LHC). Moreover, the recent data from ATLAS on production of prompt charmonia at large p(T) demonstrate a similar attenuation as observed for light hadrons. Such a universality could hardly be explained by the energy-loss mechanism, since the rate of medium induced energy loss strongly correlates with the parton mass. However, the hadronization length has been evaluated to be very short, especially at high p(T), therefore, attenuation of the high-p(T) hadrons originates mainly from the possibility to be broken-up by inelastic collisions during propagation through the dense medium. The survival probability is controlled by the effect of color transparency, which makes the attenuation dependent on the dipole size, related mainly to p(T). This naturally explains the observed universality of hadron suppression. With the same value of the transport coefficient, we predict similar suppression factors R-AA for inclusive production of pions, kaons, protons, charmonia and even bottomonia as a function of p(T )and centrality in good agreement with data.
