Kaon-Nucleon Total Cross Sections from 0.36 to 0.72 GeV/ c

Kaon-Nucleon Total Cross Sections from 0.36 to 0.72 GeV/ c The K + and K - total cross sections were measured on both hydrogen and deuterium at a series of momenta between 360 MeV/ c and 720 MeV/ c by the transmission method. The data were corrected for Coulomb and decay effects, and the isospin states were extracted. The K + N , I = 0 cross section was found to be free from resonances, although the presence of a small dip at about 700 MeV/ c was confirmed. No convincing evidence was found for structure in the K + N , I = 0 cross section, which was observed to be steeply rising with increasing momentum throughout this range. The prominence of the Λ ′ ( 1520 ) was verified in the K - N , I = 0 system in which no additional structure was seen. In the K - N , I = 1 system no new structure was clearly established, though there appears to be a small enhancement with a mass about 1600 MeV. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)

Abstract

The K + and K - total cross sections were measured on both hydrogen and deuterium at a series of momenta between 360 MeV/ c and 720 MeV/ c by the transmission method. The data were corrected for Coulomb and decay effects, and the isospin states were extracted. The K + N , I = 0 cross section was found to be free from resonances, although the presence of a small dip at about 700 MeV/ c was confirmed. No convincing evidence was found for structure in the K + N , I = 0 cross section, which was observed to be steeply rising with increasing momentum throughout this range. The prominence of the Λ ′ ( 1520 ) was verified in the K - N , I = 0 system in which no additional structure was seen. In the K - N , I = 1 system no new structure was clearly established, though there appears to be a small enhancement with a mass about 1600 MeV.
