K−p charge exchange at 5, 7 and 12 GeV/c

New combined analysis of elastic and charge exchange KN(K¯N) scattering in the Regge realm

“…Data of K − p → K 0 n (black circles) are taken from Ref. [28]. Data of K + n → K 0 p (green squares) at P Lab = 5.5, 10, and 12 GeV/c are taken from Refs.…”

“…Data of K − p → K 0 n are from Refs. [25,28,[33][34][35][36]. the complex phase, EXP[−iπα a2 (t)] for the a 2 exchange is favored in order to agree with cross section data rather than the exchange nondegenerate phase.…”

“…The respective contributions of a0(980) and a2(1320) are shown in the upper left panel. Data of K − p → K 0 n (black circles) are taken from Ref [28]…”

“…Measurements of o(K~p) to ±0.2 mb at energies up to 18 GeV have been carried out by Galbraith et al 2 These authors have also measured o{K~n), but because this measurement requires a subtraction of o{K ~p) from deuterium cross-section measurements of only ±0.4-mb accuracy, as well as the calculation of Glauber corrections, the precision is not sufficiently good to obtain a useful result for the asymptotic cross section. To get around this difficulty we have used determinations of the forward cross section of the K~p charge-exchange reaction by Astbury et al, 7 coupled with the optical theorem to determine directly the difference o(K~p) -a(K~n). This calculation assumes that the forward amplitude of the K~p charge exchange is largely imaginary, a result already known to be essentially correct and explained on the basis of Regge theory.…”
