P-odd effects in the π+-+q → μ++μ-+q', q+ anti q' → π+-+μ++μ- processes and P-odd constant of π+-qq'-interaction

P-odd effects for one-photon mechanism of muon pair production in hadron collisions conditioned by contribution of π+-+q → q'+μ++μ- and q+ anti q' → π+-+μ++μ- pion mechanisms are studied. The π+-+q →qq+γ* (γ* is virtual γ-'uantum) process is considered in Born approximation within the frames of which P-odd effects arise due to P-odd constant of π+-qq1-interaction. It is shown that in collision of non-polarized particles P-odd effects in a1+a2 → μ++μ-+X (a1 and a2 - colliding hadrons, X-nondetected set of particles) are conditioned by imaginary part of pion electromagnetic formfactor in the region of time-like momentum transferred for the considered mechanism if non-polarized muons are produced. Detection of P-odd effects in a1+a2 → μ++μ-+X due to P-invariance breaking in πq-collisions is essential for determination of P-odd constant of π+-qq'-interaction
