Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in gluon fusion
We compute the part of the two-loop virtual amplitude for the process gg → V1V2 → (l1 l̄ ′ 1)(l2 l̄ ′ 2), where V1,2 are arbitrary electroweak gauge bosons, that receives contributions from loops of massless quarks. Invariant masses of electroweak bosons are allowed to be different from each other. Our result provides an important ingredient for improving the description of gluon fusion contribut...
متن کاملPrompt photon hadroproduction at high energies in off-shell gluon-gluon fusion
The amplitude for production of a single photon associated with quark pair in the fusion of two off-shell gluons is calculated. The matrix element found is applied to the inclusive prompt photon hadroproduction at high energies in the framework of kT -factorization QCD approach. The total and differential cross sections are calculated in both central and forward pseudo-rapidity regions. The con...

Particle production from off-shell nucleons
Particle production in equilibrium and nonequilibrium quantum systems is calculated. The effects of the off-shell propagation of nucleons in medium on the particle production are discussed. Comparision to the semiclassical production rate is given. The production of mesons and hard photons in intermediate energy heavy ion collisions is considered to be sensitive to the collision dynamics and to...
متن کاملOff - shell effects on particle production ∗
We investigate the observable effects of off-shell propagation of nucleons in heavy-ion collisions at SIS energies. Within a semi-classical BUU transport model we find a strong enhancement of subthreshold particle production when off-shell nucleons are propagated. During the past 15 years semi-classical transport models have extensively and quite successfully been applied to the description of ...
