The inclusive reaction pp → λχ and the polarization of the λ

Inclusive production of neutral strange particles at 300 GeV: Triple-Regge behavior

“…Another possibility is that the polarization results from absorptive corrections to the triple-Regge diagrams. Calculations [17,18] show polarization but do not fully reproduce our data.…”

“…However, an understanding of the source of the polarization remains elusive. Many theoretical ideas have been proposed to explain the source of the polarization in the context of the Lund model, parton recombination, multiple scattering of the strange quark, gluon fusion, Regge theory, coherent scattering, low and high order QCD calculations, valence quark effects, and quark condensates [2]. However, there is, to date, no compelling explanation.…”
