Measurement of the Xi-p Scattering Cross Sections at Low Energy

Abstract

In this paper we report cross-section measurements for ${\Xi }^{-}p$ elastic and inelastic scatterings at low energy using a scintillating fiber active target. Upper limit on the total cross-section for the elastic scattering was found to be 24 mb at 90% confidence level, and the total cross section for the ${\Xi }^{-}p\to \Lambda \Lambda$ reaction was found to be $4.3_{-2.7}^{+6.3}$ mb. We compare the results with currently competing theoretical estimates.
