Jimenez-Delgado, P (2010). On the dynamical determination of strange parton distributions. In: XVIII International Workshop on Deep-Inelastic Scattering and Related Subjects, DIS 2010, Convitto della Calza, Firenze, Italy, 19 April 2010 - 23 April 2010.
The dynamical parton distributions of the nucleon are generated radiatively from positive definite (valencelike) input distributions at an optimally chosen low resolution scale (Q_0^2 < 1 GeV^2). For the strange distribution in particular, it has been assumed that vanishing strange input distributions at this low scale is an appropriate choice. By confronting predictions derived from our (GJR08) NLO dynamical parton distributions with recent neutrino dimuon production measurement from NuTeV we show that this is indeed the case, and that little improvement is achieved by using a more general ansatz. Nevertheless, the data induce an asymmetry in the strange sea which is found to be small and positive in agreement with previous results.
