Inclusive production of antihyperons in nC-interactions

The EXCHARM Collaboration


(Received: 7 June 2002 / Revised version: 23 January 2003 / Published online: 3 March 2003 )

Abstract
The inclusive production cross-sec tions of $\bar\Lambda^0$, $\bar\Xi^+$, and $\bar\Sigma(1385)^\pm$ in neutron-carbon interactions at $\sim 51$ GeV mean energy of neutrons have been measured. The parameters n and b of differential cross-sec tion parametrisation $(1-\vert x_F\vert)^n\cdot\exp (-bp_t^2)$, where xF is the Feynman variable, pt is the transverse momentum, have been obtained. The kinematic region of validity of the parametrisation has been defined. Results are compared with published experimental data.
