Jet and dijet production in heavy-ion collisions
I will discuss recent developments in the theory of jets in ultra-relativistic nuclear collision, with an emphasis on heavy flavor production. Starting with inclusive jets, I will show how the technique of semi-inclusive jet functions, first developed in the framework of soft collinear effective theory, can be applied to c-jets and b-jets in heavy ion collisions. For the case of dijets, I will present the first calculation of the dijet mass modification in nucleus-nucleus reactions. The advantage of this new observable is that the energy loss effects on the individual jets combine to give enhanced sensitivity to the transport properties of the quark-gluon plasma.
