We estimate the cross-section and asymmetry relevant for the production of forward jets in polarised deep inelastic scattering in the region of small values of x which can be probed at possible polarised HERA measurements. The kinematical cuts implemented in our analysis are the same as those which were used in the unpolarised deep inelastic scattering at HERA. The calculations are based on the...

We point out that the measurement of target spin depolarization Dnn in the p̄p → Λ̄Λ reaction may test dynamical mechanisms invoked to explain the proton spin puzzle revealed by polarized deep–inelastic scattering experiments. In particular, models with negatively polarized s̄s pairs in the proton wave function predict Dnn < 0, whereas models with positively polarized gluons would predict Dnn > 0....

We demonstrate that the angular distribution of hadrons produced in semiinclusive deep inelastic final states is related to the inclusive longitudinal structure function. This relation could provide a new method of accessing FL(x,Q 2) in deep inelastic scattering measurements. The internal structure of the proton as probed in deep inelastic lepton-proton scattering can be parameterised in terms...

The solutions of the homogeneous nonlinear Boltzmann equation for inelastic Maxwell models, when driven by different types of thermostats, show, in general, overpopulated high energy tails of the form approximately exp(-ac), with power law tails and Gaussian tails as border line cases. The results are compared with those for inelastic hard spheres, and a comprehensive picture of the long time b...

We calculated the inelastic electron impact excitation cross sections of He+ by electrons for a model helium atom to examine the onset of the signature of quantum chaotic scattering in this simple system. We find Ericson fluctuations EF in the calculated inelastic scattering cross sections only when the impact energies lie within about 0.21 eV below the double ionization threshold. We also disc...

The folding formalism for the nucleon-nucleus optical potential and inelastic form factor is applied to study elastic and inelastic proton scattering on 30−40S isotopes. A recently developed realistic density dependent M3Y interaction, well tested in the folding analysis of nucleus-nucleus elastic and inelastic scattering, is used as effective NN interaction. The nuclear ground state and transi...
