Gluon corrections to p-odd effects at muon pair production in hadron collisions

For muon pair production in hadron-hadron collisions the contribution of a single-photon mechanism and the mechanism due to neutral weak muon and hadrons currents is studied. In a general case this interference leads to three types of P-odd dependence on polar (THETA) and azymuthal (phi) angles of muon production namely sin 2THETA sin phi, sin THETA sin phi and sin2 THETA sin 2phi, the study of which allows in principle to divide P-invariance violation effects in muon and hadron neutral weak currents. The interference of the two mechanisms leads to P-odd angular distribution asymmetry which is characterized by two types of THETA and phi dependences, cos THETA and sin THETA cos phi. Using the Weinberg model for describing neutral weak currents two mechanisms of muon pair production in hadron collisions, namlly g+q→q+μ+++μ- and q+anti q→g+μ++μ- (q is quark, g - gluon), in each of them the contribution of γ quanta and Z boson exchange is taken into account. It is shown in a lower order by quark-gluon interaction constant that in non polarized particles interaction (polarization of finite muons is not detected) P-odd effects do not arise while the charge asymmetry arises. This asymmetry is calculated in various coordinate systems used in the course of discussion on muon pair angular distribution
