Effects of p invariance violation in inclusive processes of the 1/2 spin particle production at colliding e+e- -beams
Description
For the process of inclusive 1/2 spin baryon production at colliding electron-positron beams the contribution of two mechanisms: electromagnetic single photon mechanism and mechanism caused by electron and hadrons neutral weak currents is taken into account. It is shown that the cross section of polarized baryons production at the random polarized electron and positron collision is determined generally by five real structural functions of single photon mechanism by five complex structural functions, which describe an interference of electromagnetic and vector part of neutral weak hadron currents as well as by five complex functions which describe the interference of electromagnetic and axial part of the neutral weak hadron currents. All these structural functions are calculated in terms of corresponding form factors for two particle processes e+e-→p+anti p, e+e-→anti p+Δ and for the processes of baryon and antibaryon production with different mass and spatial parity values. The correspondence between various equivalent descriptions of polarized baryon states is investigated in detail
