The transverse momentum distributions for\(\rho ^0 (770),f_2 (1270),K*^0 (892),\bar K*^0 (892)\) and ϕ (1020) have been studied in thept region between 2 and 4 GeV/c and central rapidity. The data analysed come from the WA77 experiment at CERN with a 300 GeV/c π− beam incident on a Be target. These distributions are well described by the functionpt−n withn∼8. A sample of simulated events from the Lund Monte Carlo in the same experimental conditions reproduces well the data.

Inclusive $K^*$0 (890) and $\bar{K}^*$0 (890) Production on Beryllium by $K^-$ and $\pi^-$ at 175-{GeV}

The reactions\(K^ -Be \to {}^(\bar K^) *^0 (890)X,\pi ^ -Be \to {}^(\bar K^) *^0 (890)X\), have been studied in a 175 GeV unseparated hadron beam in the kinematic range 0<xF<1.0 andpT2<5 GeV2. Integrated cross-sections and the dependence of the cross-sections on the longitudinal and transverse momentum are presented, together with quark counting rules predictions. The nuclear dependence ofK− fragmentation intoK*0(890) with respect to Feynmanx is investigated from hydrogen to beryllium.
