Strange particle production in ν and anti ν neon interactions

The inclusive production of K0's and ν's has been investigated in neutrino and antineutrino interactions in BEBC, filled with a neon-hydrogen mixture. The inclusive rates for the 3083 (1022) ν(anti ν) induced charged current events are (23.0 +- 1.7)% ((21.9 +- 2.8)%) for K0's and (5.7 +- 0.7)% ((6.5 +- 1.2)%) for ν's. The general behaviour of the K0's and ν's is found to be similar to that in νp interactions and π+p interactions at lower . In the hadronic c.m.s. K0's are produced mostly forwards. ν's predominantly in the backward hemisphere. The data indicate that the K0's produced in anti ν interactions on average carry a larger fraction of the total available momentum than those in ν induced reactions. The dependences of the average transverse momentum on the variables Q2, W2 and Bjorken x are presented. (orig.)
