Looking for strangeness with neutrino-nucleon scattering
نویسنده
چکیده
The possibility to determine the axial strange form factor of the nucleon from elastic neutrino-nucleon scattering experiments is studied. The existing experimental information is shortly mentioned and several observables which could be measured in the near future at new neutrino facilities are discussed.

Strangeness in the nucleon : neutrino – nucleon and polarized electron – nucleon scattering
After the EMC and subsequent experiments at CERN, SLAC and DESY on the deep inelastic scattering of polarized leptons on polarized nucleons, it is now established that the Q 2 = 0 value of the axial strange form factor of the nucleon, a quantity which is connected with the spin of the proton and is quite relevant from the theoretical point of view, is relatively large. In this review we conside...

متن کاملThe Paschos-Wolfenstein relation in a hadronic picture
Abstract The Paschos-Wolfenstein (PW) relation joins neutraland charged-current (anti)neutrino cross sections into an expression that depends on the weak mixing angle sin θW in a straightforward way. Contrary to the traditional approach with partonic degrees of freedom, in this work, we adopt a model built on hadronic degrees of freedom to perform a study of the PW relation at intermediate ener...
متن کاملStrangeness and Hadron Structure
The nucleon wave function may contain a significant component of s̄s pairs, according to several measurements including the π-nucleon σ term, charm production and polarization effects in deep-inelastic scattering. In addition, there are excesses of φ production in LEAR and other experiments, above predictions based the naive Okubo-Zweig-Iizuka rule, that may be explained if the nucleon wave func...
متن کاملIntrinsic Polarized Strangeness and Λ Polarization in Deep-Inelastic Production
We propose a model for the longitudinal polarization of Λ baryons produced in deep-inelastic lepton scattering at any xF , based on static SU(6) quark-diquark wave functions and polarized intrinsic strangeness in the nucleon associated with individual valence quarks. Free parameters of the model are fixed by fitting NOMAD data on the longitudinal polarization of Λ hyperons in neutrino collision...
