ResBos programs compute the fully differential
cross section d(sigma)/(dQdydQTd(Omega)) for
-> (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
observed electroweak particles (leptons, prompt photons, or Z bosons).
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.
