Jet quenching phenomenology from soft-collinear effective theory with Glauber gluons
ORAL
Abstract
We present the first application of a recently-developed effective theory of jet propagation in matter ${\rm SCET_G}$ to inclusive hadron suppression in nucleus-nucleus collisions at the LHC. ${\rm SCET_G}$-based splitting kernels allow us to go beyond the traditional energy loss approximation and unify the treatment of vacuum and medium-induced parton showers. In the soft gluon emission limit, we establish a simple analytic relation between the QCD evolution and energy loss approaches to jet quenching. We quantify the uncertainties associated with the implementation of the in-medium modification of hadron production cross sections and show that the coupling between the jet and the medium can be constrained with better than 10\% accuracy.
