Abstract
The production of heavy quarks is considered in the quark-parton model. The model is shown to account for the energy-dependent effects of large produced masses. By considering the inclusive, charged-current neutrino scattering data as a function of energy, it is possible to distinguish between the standard four-quark model and models with right-handed currents and additional heavy quarks. It appears that the present data favor the latter models, and allow estimates of the masses of new quarks.
