Induced non-Abelian Chern-Simons effective action in very special relativity
Z. Haghgouyan, M. Ghasemkhani, R. Bufalo +1
In this paper, we study the one-loop induced effective action for a non-abelian gauge field in the very special relativity (VSR) framework in a -dimensional spacetime. We sh…
Induced CP-violation in the Euler-Heisenberg Lagrangian
M. Ghasemkhani, V. Rahmanpour, R. Bufalo +2
In this paper, we examine the behaviour of the Euler-Heisenberg effective action in the presence of a novel axial coupling among the gauge field and the fermionic matter. This axia…
Adler-Bell-Jackiw anomaly in VSR electrodynamics
R. Bufalo, M. Ghasemkhani, A. Soto
In this paper, we examine the problem of anomalies of the fermionic currents in the context of the very special relativity (VSR). We consider the VSR contributions to the triangle…
Induced Maxwell-Chern-Simons Effective Action in Very Special Relativity
R. Bufalo, M. Ghasemkhani, Z. Haghgouyan +1
In this paper, we study the one-loop induced photon's effective action in the very special relativity electrodynamics in spacetime (VSR-QED). Due to the presence of n…
Photon-Photon Scattering in Very Special Relativity
Jorge Alfaro, Alex Soto
Starting from the Mandelstam-Leibbrandt prescription, we introduce a general rule for the null vector to compute any integral and diagram with an arbitrary numbe…
Meson spectrum in revisited
Jorge Alfaro, Alex Soto
Recently it has been shown that in two dimensions is possible to add new Lorentz invariant terms built with fractions containing the null vector . In this work, we have…
Schwinger Model à la Very Special Relativity
Jorge Alfaro, Alex Soto
In this work, we show that Lorentz invariant theories in dimensions admit new terms inspired by Very Special Relativity (VSR) theories. We have studied the Schwinger model in…
On the photon mass in Very Special Relativity
Jorge Alfaro, Alex Soto
In Very Special Relativity (VSR) a gauge invariant photon mass is allowed. We explore some consequences of keeping this parameter not zero. VSR-Maxwell equations are presented. In…
B-modes and the sound speed of primordial fluctuations
Gonzalo A. Palma, Alex Soto
It was recently shown that a large value of the tensor to scalar ratio implies a constraint on the minimum value of the sound speed of primordial curvature perturbations…
