One-loop off-shell quark-gluon vertex in arbitrary gauge and dimensions: a streamlined approach through the second-order formalism of QCD
Victor Miguel Banda Guzmán, Adnan Bashir
The standard Feynman rules used for perturbative calculations in quantum chromodynamics (QCD) are derived from a Lagrangian that is first-order in derivatives. It includes a three-…
One loop reduced QED for massive fermions within an innovative formalism
Victor Miguel Banda Guzmán, Adnan Bashir, Luis Albino +1
We carry out a detailed study of the three-point fermion-photon interaction vertex at one loop order for massive fermions in reduced quantum electrodynamics. This calculation is ca…
Use of flavor projection operators to construct baryon-meson scattering amplitudes in the expansion
Victor Miguel Banda Guzmán, Ruben Flores-Mendieta, Johann Hernandez
An flavor projection operator technique is implemented to construct the baryon-meson scattering amplitude in the framework of the expansion of QCD, where is t…
One-loop fermion-photon vertex in arbitrary gauge and dimensions: a novel approach
Victor Miguel Banda Guzmán, Adnan Bashir
We compute one-loop electron-photon vertex with fully off-shell external momenta in an arbitrary covariant gauge and space-time dimension. There exist numerous efforts in literatur…
Gyromagnetic g_s factors of the spin-1/2 particles in the (1/2+,1/2-,3/2-) triad of the four-vector spinor, ψ_μ, irreducibility, and linearity
E. G. Delgado Acosta, V. M. Banda Guzmán, M. Kirchbach
We show that the spin (1/2-) particle from the (1/2,1)+(1,1/2) Lorentz irreducible sector of the four-vector spinor can not be described within a linear formalism but behaves as a…
Bosonic and fermionic Weinberg-Joos (j,0)+ (0,j) states of arbitrary spins as Lorentz-tensors or tensor-spinors and second order theory
E. G. Delgado Acosta, V. M. Banda Guzman, M. Kirchbach
We propose a general method for the description of arbitrary single spin-j states transforming according to (j,0)+(0,j) carrier spaces of the Lorentz algebra in terms of Lorentz-te…
