Polarization Effects In Hadron-Hadron Scatterings
Abstract
In the case of diffraction scattering of hadrons by hadrons, a nonzero
polarization of the scattered particles arises, which is related to the
logarithmic derivative of the differential scattering cross section.
Polarization changes sign in those reactions whose angular distributions
contain the second diffraction maximum. On the basis of the assumption on the
diffraction behavior of the quark amplitudes, it can be concluded that the quark
scattering amplitude on the quark exhibits only the first principal maximum,
the amplitude of annihilation scattering of quarks exhibits two maxima. This
fact allows the behavior of polarizations of finite baryons as a function of
the momentum transfer, and also obtains a relation between the polarizations of
baryons in various reactions. The polarization sign is determined by the nature
of the spin-orbit interaction: for the repulsive and attraction potential,
there must be opposite signs the polarization. The polarization of the recoil
particles vanishes, where the differential cross sections have a minimum.
