Our paper on the measurement of high transverse momentum charged particle suppression, accepted by the European Physical Journal C (EPJC) in February 2012, was recently published and featured in the cover of the new EPJC issue (March 2012). The figure that was featured in the cover is the main result of the paper showing the suppression of the charged particles over a large transverse momentum range, where a number of theoretical predictions show large variation, in particular at high transverse momentum regime, exhibiting large theoretical uncertainty. Together with other jet quenching related quantities that we have measured, this measurement should help elucidate the mechanism of jet quenching and the properties of the medium produced in heavy-ion collisions at collider energies.
