Soft end-point and mass corrections to the eta' g*g* vertex function
S. S. Agaev, M. A. Gomshi Nobary
Power-suppressed corrections arising from end-point integration regions to the space-like vertex function of the massive eta'-meson virtual gluon transition eta' - g*g* are compute…
Pion distribution amplitude from holographic QCD and the electromagnetic form factor F_pi(Q2)
S. S. Agaev, M. A. Gomshi Nobary
The holographic QCD prediction for the pion distribution amplitude (DA) is used to compute the pion spacelike electromagnetic form factor within the QCD lig…
Relative Cohen--Macaulayness of bigraded modules
Ahad Rahimi
In this paper we study the local cohomology of all finitely generated bigraded modules over a standard bigraded polynomial ring which have only one nonvanishing local cohomology wi…
Ground state heavy baryon production in a relativistic quark-diquark model
M. A. Gomshi Nobary, R. Sepahvand
We use current-current interaction to calculate the fragmentation functions to describe the production of spin-1/2, spin-1/2 and spin-3/2 baryons with massive constituents in a…
Wick ordering for coherent state quantization in 1+1 de Sitter space
A. Rabeie, E. Huguet, J. Renaud
We show that the coherent state quantization of massive particles in 1+1 de Sitter space exhibits an ordering property: There exist some classical observables and such th…
