Electroproduction of a large invariant mass photon pair
A. Pedrak, B. Pire, L. Szymanowski +1
We study the exclusive electroproduction of a photon pair in the kinematical regime where the diphoton invariant mass is large and where the nucleon flies almost in its original di…

Exclusive production of a large mass photon pair
A. Pedrak, B. Pire, L. Szymanowski +1
The scattering amplitude for photoproduction of a large invariant mass diphoton in the generalized Bjorken regime has a very peculiar and interesting analytical structure. The lead…

On generation of the Bargmann-Moshinsky basis of SU(3) group
S. Vinitsky, C. Burdik, A. Gusev +4
An efficient procedure of orthonormalisation of the Bargmann-Moshinsky (BM) basis is examined using analytical formulas of the overlap integrals of the BM basis. Calculations of co…
