On recent evidence for higher-twist effects in semi-inclusive deep-inelastic neutrino scattering

Abstract We discuss recent experimental evidence for higher-twist contributions in ν N → μ − h + X . We show that the observed effects are equally well reproduced by a longitudinal phase space model, with no free parameters. With an antineutrino beam instead the corresponding effect predicted by the LPS model is found to be opposite to that expected from the high-twist calculation, and thus a cleaner test of the theory is possible.
