Query: Evolution equations for extended dihadron fragmentation functions   We consider dihadron fragmentation functions, describing the fragmentation of
a parton in two unpolarized hadrons, and in particular extended dihadron
fragmentation functions, explicitly dependent on the invariant mass, $M_h$, of
the hadron pair. We first rederive the known results on $M_h$-integrated
functions using Jet Calculus techniques, and then we present the evolution
equations for extended dihadron fragmentation functions. Our results are
relevant for the analysis of experimental measurements of
two-particle-inclusive processes at different energies.
