INVESTIGATION OF INCLUSIVE PRODUCTION OF K0 AND K-ASTERISK(892)0 MESONS IN K(+)A INTERACTIONS AT 11.2 GEV

Inclusive production of K0 and K*(892)0 mesons in K+ A-interactions (A = Be, Cu, Pb) at the energy 11.2 GeV has been investigated to study hadronisation of the leading sBAR-quark; the results are presented. Double differential cross sections d2sigma/dx(f)dp(t)2 were measured in the region of incident particle fragmentation (0.4 less-than-or-equal-to x(f) less-than-or-equal-to 1, p(t) less-than-or-equal-to 0.5 GeV/c). The experimental data obtained were analysed on the basis of the Lund model FRITIOF and a quark-gluon model that takes into account colour screening and hadron formation length effects. The experimental data confirm the picture of hadronisation of the leading sBAR-quark developed in the latter model.
