ResBos programs compute the fully differential cross section d(sigma)/(dQdydQTd(Omega)) for processes h1 h2 -> (V)-> l1 l2 X, where  h1 and h2 are hadrons (pion or nucleons), V is an intermediate virtual particle or state (e.g., a virtual electroweak boson), and l1 and l2 are observed electroweak particles (leptons, prompt photons, or Z bosons).  Q, QT, and y are the invariant mass, transverse momentum, and rapidity of the intermediate state V in the laboratory frame (center-of-mass frame of the initial hadrons). Omega is the solid angle of the 3-momentum of l1  in the Collins-Soper rest frame of V. The production and decay of V are evaluated using exact matrix elements. Electroweak corrections to the width of V and spin correlations between the initial- and final-state particles are included when applicable.
