High-energy diffraction dissociation ofKL0into exclusive final states

Abstract

We have observed diffraction dissociation of K; mesons with a carbon target into the exclusive final states K~T + T -, ~j w , and K j b . The diffraction production cross section for these states is not strongly dependent on the incident energy, varying at most by 30% between 75 and 150 GeV. The mass distributions do not change appreciably as a function of laboratory energy. The ratio of the diffractive mass-threshold production of K
