Inclusive production ofK s 0 , K s 0 K s 0 andK*±(892) in\(\bar pp\) interactions at 3.0, 3.5, 4.0 and 4.5 GeV/c

InclusiveK s 0 andK s 0 K s 0 production in\(\bar pp\) interactions at 3.0, 3.5, 4.0 and 4.5 GeV/c are studied. Cross sections ofK s 0 , K s 0 K s 0 andK*±(892) are presented for each incident momentum. The production ofK s 0 andK*±(892) through annihilation process is investigated. It is found that the annihilation process is dominant but decreases with incident momentum. The annihilation process is compared withe+e− interactions. Remarkable similarity between them is found in the\({{x_0 = 2E(K_s^0 )} \mathord{\left/ {\vphantom {{x_0 = 2E(K_s^0 )} {\sqrt s }}} \right. \kern-\nulldelimiterspace} {\sqrt s }}\) distribution. Events with two detectedK s 0 's are analyzed. The result shows theK s 0 K s 0 pairs are produced in the central region of c.m. system and there is a clearS* signal in theK s 0 K s 0 effective mass distribution.
