Dimuon distribution from production of heavy particles in high-energyνandν¯reactions

Dimuon distributions from the production of heavy particles in $\nu$- and $\overline{\nu }$-induced reactions are obtained within the framework of the quark-parton model. General qualitative features independent of the model are pointed out. Available data are consistent with the production of at least one particle, of mass 1.8 GeV/${\mathit{c}}^2$, in $\nu$-induced reactions, with ordinary ($V-A$) currents, and perhaps one more heavier particle, of mass around 3.5 GeV/${\mathit{c}}^2$ to 4.5 GeV/${\mathit{c}}^2$, with ($V+A$) currents, in $\overline{\nu }$-induced reactions. Methods for determining production probability functions from dimuon distributions are pointed out.
