Measurement of the pn -> dK+K- total cross section close to threshold

Measurements of the pd -> p(sp) dK(+) K- reaction, where psp is a spectator proton, have been undertaken at the Cooler Synchrotron COSY-Julich by detecting a fast deuteron in coincidence with a K+K- pair in the ANKE facility. Although the proton beam energy was fixed, the moving target neutron al...

Measurements of the pd -> p(sp) dK(+) K- reaction, where psp is a spectator proton, have been undertaken at the Cooler Synchrotron COSY-Julich by detecting a fast deuteron in coincidence with a K+K- pair in the ANKE facility. Although the proton beam energy was fixed, the moving target neutron allowed values of the nonresonant quasifree pn -> dK(+) K- total cross section to be deduced up to an excess energy epsilon approximate to 100 MeV. Evidence is found for the effects of K- d and K (K) over bar K final state interactions. The comparison of these data with those of pp -> ppK(+) K- and pp -> dK(+) (K) over bar (0) shows that all the total cross sections are very similar in magnitude.
