نویسنده
چکیده
I present ongoing developments on hybrid models which combine the potential model, for the description of the background, with the R-matrix model, for the description of discrete states. Physical parameters of discrete states are converted into formal R-matrix parameters, taking into account the potential background. The nuclear part of this potential is constructed by a new variant of an inversion method based on supersymmetric quantum mechanics. The method is illustrated on C + α S-wave elastic phase shifts.

The CLAS data on the photo-production of K + off the proton are utilised to study reaction mechanism of the process in frame of the isobaric approach. The missing D 13 resonance is shown to be important for successful description of the data in the whole kinematical region. Constructed models provide satisfactory predictions for the process.

The Feshbach theory of the optical potential naturally leads to a microscopic description of scattering in terms of the many-body self-energy. We consider a recent calculation of this quantity for O and study the possibility of applying it at astrophysical energies. The results obtained for the phase shifts and the O(p,γ) capture suggest that such studies are feasible but the calculations requi...

We have studied the null-plane hamiltonian structure of the free Yang-Mills fields and the scalar chromodynamics (SQCD4). Following the Dirac’s procedure for constrained systems we have performed a detailed analysis of the constraint structure of both models and we give the generalized Dirac brackets for the physical variables. In the free Yang-Mills case, using the correspondence principle in ...

Under certain circumstances the Chern-Simons 3-form is exact (or is a sum of exact forms). Its volume integral can be written as a surface term, in a " holographic " representation.
