Phenomenological model for the Kbar N --> K Xi reaction
A phenomenological model for the Kbar N --> K Xi reaction is suggested. The
model includes s and u channel exchanges by Lambda, Sigma, Sigma(1385), and
Lambda(1520) and s channel exchanges by above-threshold hyperonic resonances.
Explicit expression for the propagator for a particle with spin 7/2 is
presented. High-mass and high-spin resonances play a significant role in the
process. We deal with the whole set of existing experimental data on the cross
sections and polarizations in the energy range from the threshold to 2.8 GeV in
the center-of-mass system and reach a good agreement with experiments.
Applications of the model to other elementary reactions of Xi production and to
Xi hypernuclear spectroscopy are briefly discussed.Comment: Published version; minor change
HIGH-ENERGY PARTICLE DATA. VOLUME III. KINEMATICS OF PARTICLES AS A FUNCTION OF MOMENTUM
Kinematic quantities are plotted as a function of particle momentum for the most common elementary particles. Dynamic quantities as a function of incident-particle momentum are plotted for interactions of most of these particles with a proton. Some techniques of relativistic kinematics are also included.
