Phase-shift analysis of K+N→KN scattering in the I=0 state up to 1.5 GeV/c

Abstract Results are presented of energy-dependent and energy-independent phase-shift analyses below 1.5 GeV/c for K + N→KN, I = 0 scattering.

Cross sections of final states produced in KN interactions at 3 GeV/c

Abstract Cross sections of final states produced in K − n interactions at 3 GeV/ c are presented. The results, obtained in a 7 events/ub bubble chamber exposure with deuterium, are compared with results from an earlier K − p exposure at the same incident K − momentum.

K+d interactions between 0.6 and 1.5 GeV/c

Abstract A bubble chamber experiment is described in which observations were made of positive kaon interactions in deuterium. Partial cross sections are given at 13 kaon momenta in the range 0.64–1.51 GeV/ c . The computation of the free-neutron partial inelastic cross sections is discussed. From these results and from previously measured K + p data the (K + N) I =0 partial cross sections are derived.

Differential cross sections for K+n elastic scattering between 0.64 and 1.51 GeV/c

Abstract We present experimental results on the K + n → K + n differential cross sections measured in deuterium at 13 momenta between 0.64 and 1.51 GeV/ c .

Study of the reactions K−n → Λπ− and K−n → Σoπo at 3 GeV/c

Abstract The total and differential cross sections of the reactions K − n → Λπ − , K − n → Σ o π − and K − n → Σ − π o , as well as the Λ polarization in the first reaction, have been measured at an incident K − momentum of 3 GeV/ c .

Differential cross sections for K+n charge-exchange scattering in deuterium between 0.64 and 1.51 GeV/c

Abstract We present results on the differential cross sections for the process K + n → K 0 p extracted from the reaction K + d → K 0 pp measured at 13 momenta between 0.64 and 1.51 GeV/ c .

Baryon exchange in the reactions K−n → Yπ− at 3 GeV/c

At 3 GeV/c, the total and differential cross sections of the reactions K−n → Yπ− have been determined for nine S = −1 baryonic states. Backward peaks associated with a dip near u = −0.2 are observed in many cases. They have been interpreted, for the isospin-zero Y-states, in terms of a proton-exchange mechanism. The backward peaks in the reactions K−n → Λπ− and K−n → Σoπ− have been more quantitatively related to the backward πN → Nπ differential cross sections at the same energy. This comparison leads to the conclusion, that the first reaction is dominated by nucleon exchange, whereas the second one requires a more complex exchange mechanism.

Coherent K+d interactions between 0.64 and 1.51 GeV/c

Abstract Data are presented at 13 momenta between 0.64 and 1.51 GeV/ c for the coherent processes K + d → K + d, K + d→ K 0 d π + and K + d → K + d π + π − . Distributions for K + d elastic scattering are given in the (0.03 t | c ) 2 range.

The reactions K−n → K∗−n and K−n → KoN∗− at 3 GeV/c

The production and decay characteristics of the K∗(895) and N∗(1236) are studied in the reactions: K−n → K∗−n and K−n →KoN∗−. The results are compared with the predictions of the absorption model.

Quasi-two-body K+N interactions below 1.5 GeV/c

Abstract The production and decay of the quasi-two-body final states KΔ(1232) and K ∗ (892)N produced in K + d interactions below 1.5 GeV/ c have been studied in a bubble chamber experiment.
