An application of the absorption model to the reactions\(p\bar p \to Y\bar Y\)

摘要: We present a set of calculations the reaction\(p\bar p \to Y\bar Y\) in antiproton laboratory momentum range from 3 GeV/c to 7 GeV/c. The process is assumed take place through K* exchange only, and are performed within framework absorption model (the distorted wave Born approximation). obtain good description angular dependence cross-section for three channels\(\Lambda \bar \Lambda ,\Lambda \Sigma ^0 + \) \(\Sigma ^ \overline {\Sigma } whole energy range. However, wrong, appears worst channel\(\Lambda \), where best described.
