“…There have been very little data taken (but see [4,5]) in an ordinary sense since the most recent partial-wave analyses [15,16,17,18,19,20,21,22,23,24,25,26,27,28]. The suggestion of the existence of a possible pentaquark resonance (see Ref.…”

“…Following the measurement of the ratio of total cross sections [4,5], a number of suggestions were made to explain the results, among the principal ones being a partial deconfinement of quarks, an interaction with exchanged mesons in the nucleus and a modification of the K + N interaction through exchanged mesons. In order to understand which of these possible scenarios might be the right one, a detailed comparison with experiment is in order.…”

We have performed a partial-wave analysis of K + -nucleon scattering in the momentum range from 0 to 1.5 GeV/c addressing the uncertainties of the results and comparing them with several previous analyses. It is found that the treatment of the reaction threshold behavior is particularly important. We find a T=0 scattering length which is not consistent with zero, as has been claimed by other analyses. The T=0 phase shifts for ℓ > 0 are consistent with a pure spin-orbit potential. Some indications for the production of a T=0 pentaquark with spin-parity D5/2+ are discussed.

“…For K + interaction with nucleons in the momentum range of 400-800 MeV/c the relevant energies in the medium are lower than the cm beam energy by up to 30 MeV. Total cross sections for K + on D, 6 Li, C, Si and Ca were measured in the early 1990s at four momenta below 800 MeV/c [5][6][7][8] . The same set of transmission measurements was later reanalysed to determine not only total cross sections but also reaction cross sections, that are less dependent on applied corrections [9].…”

Abstract. Simple in-medium meson-nucleon kinematics has been applied recently in calculations of strong interaction effects in kaonic atoms, pionic atoms and elastic scattering of low energy pions by nuclei. More sensitive tests of this approach are possible with K + -nucleus interactions below 800 MeV/c because of the superior penetration of kaons into nuclei. The energy dependence of calculated reaction and total cross sections for K + on 6 Li, C, Si and Ca agrees better with experiment when this approach is used. Calculated absolute scales are in full agreement with experiment for the very low density nucleus 6 Li whereas calculations are 23±4 % too low for C, Si and Ca, thus quantifying phenomenologically the enhancement in the nuclear medium observed before.
