Graviton Mass Bounds in Very Special Relativity from Binary Pulsar's Gravitational Waves
Alessandro Santoni, Jorge Alfaro, Alex Soto
In this work we study the gravitational radiation produced by a keplerian binary system within the context of Very Special Linear Gravity (VSLG), a novel theory of linearized gravi…
Unified description of corpuscular and fuzzy bosonic dark matter
Nick P. Proukakis, Gerasimos Rigopoulos, Alex Soto
We derive from first principles equations for bosonic, non-relativistic and self-interacting dark matter which can include both a condensed, low momentum "fuzzy" component and one…
Schwinger-Dyson equations and mass generation for an axion theory with a PT symmetric Yukawa fermion interaction
N. E. Mavromatos, Sarben Sarkar, A. Soto
A nonperturbative Schwinger-Dyson analysis of mass generation is presented for a non-Hermitian PT-symmetric field theory in four dimensions of an axion coupled to a Dirac fermion.T…
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…
Cosmology in the presence of diffeomorphism-violating, nondynamical background fields
Carlos M. Reyes, Marco Schreck, Alex Soto
We consider diffeomorphism violation, which is parameterized by nondynamical background fields of the gravitational Standard-Model Extension (SME), and study its effects on the tim…
Impossibility of obtaining a CP-violating Euler-Heisenberg effective theory from a viable modification of QED
M. Ghasemkhani, V. Rahmanpour, R. Bufalo +1
In this paper, we examine the CP-violating term of the Euler-Heisenberg action. We focus in the aspects related with the generation of such a term from a QED-like model in terms of…
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…
Dynamical Majorana Neutrino Masses and Axions II: Inclusion of Axial Background and Anomaly Terms
Nick E. Mavromatos, Alex Soto
We extend the study of a previous publication \cite{amsot} on Schwinger-Dyson dynamical mass generation for fermions and pseudoscalar fields (axion-like particles (ALP)), in field…
Dynamical Majorana Neutrino Masses and Axions
Jean Alexandre, Nick E. Mavromatos, Alex Soto
We discuss dynamical mass generation for fermions and pseudoscalar fields (axion-like particles (ALP)), in the context of effective theories containing Yukawa type interactions bet…
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…
Consistency relations for sharp inflationary non-Gaussian features
Sander Mooij, Gonzalo A. Palma, Grigoris Panotopoulos +1
If cosmic inflation suffered tiny time-dependent deviations from the slow-roll regime, these would induce the existence of small scale-dependent features imprinted in the primordia…
Consistency relations for sharp features in the primordial spectra
Sander Mooij, Gonzalo A. Palma, Grigoris Panotopoulos +1
We study the generation of sharp features in the primordial spectra within the framework of effective field theory of inflation, wherein curvature perturbations are the consequence…
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…
