Behavior of the Hadron Potential at Large Distances and Properties of the Hadron Spin-flip Amplitude
The impact of the form of the hadron potential at large distances on the
behaviour of the hadron spin-flip amplitude at small angles is examined. The
-dependence of the spin-flip amplitude of high energy hadron elastic
scattering is analyzed under different assumptions on the hadron interaction.
It is shown that the long tail of the non-Gaussian form of the hadron potential
of the hadron interaction in the impact parameter representation leads to a
large value of the slope of the spin-flip amplitude (without the kinematical
factor ) as compared with the slope of the spin-non-flip amplitude.
This effect can explain the form of the differential cross section and the
analyzing power at small transfer momenta. The methods for the definition of
the spin-dependent part of the hadron scattering amplitude are presented. A
possibility to investigate the structure of the hadron spin-flip amplitude from
the accurate measure of the differential cross section and the spin correlation
parameters is shown.Comment: 13 pages, LaTeX, 3 figures.p
Can experimental tests of Bell inequalities performed with pseudoscalar mesons be definitive?
We discuss if experimental tests of Bell inequalities performed with
pseudoscalar mesons (K or B) can be definitive. Our conclusion is that this is
not the case, for the efficiency loophole cannot be eliminated.Comment: submitted for publicatio
