Discontinuity Method for Evaluating Scattering Amplitudes within the Worldline Formalism
Victor Miguel Banda Guzmán
The worldline formalism offers an alternative framework to the standard diagrammatic approach in quantum field theory, grounded in first-quantized relativistic path integrals. Over…
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…
