Polarized strangeness in the nucleon
A large violation of the Okubo-Zweig-Iizuka rule was discovered in the annihilation of stopped antiprotons. The explanation of these experimental data is discussed in the framework of the model assumed that the nucleon strange sea quarks are polarized.
متن کاملStrangeness 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 کاملNucleon Resonances in Meson Nucleon Scattering with Strangeness Production
An effective Lagrangian model in a coupled channels framework is applied to extract nucleon resonance parameters. In the K-matrix approximation, we simultaneously analyze all the available data for the transitions from πN to five possible meson-baryon final states, πN, ππN, ηN,KΛ, and KΣ, in the energy range from πN threshold up to √ s = 2 GeV. In this work, we focus our efforts on the KΣ chann...

متن کاملLooking for strangeness with neutrino-nucleon scattering
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.
