QED vertex and anomalous magnetic moment in the presence of a magnetic field

Alejandro Ayala, Enrique Muñoz, Marcelo Loewe +2

We compute the fermion-photon vertex in QED in the presence of a constant and uniform magnetic background up to one-loop order. We show that even at tree-level, the vertex is modif…

Electric field fluctuations and renormalization group flows in a self-interacting scalar field theory

Melanie Martínez, Enrique Muñoz, Marcelo Loewe

We consider a self interacting charged scalar field represented by the complex λϕ4 model, embedded in a background electric field exhibiting classical stochastic fluctuations. We s…

Dilepton Production in a Rotating Thermal Medium: The Rigid Rotation Approximation

Jorge David Castaño-Yepes, Enrique Muñoz

We investigate dilepton production in a thermalized quark--gluon plasma subject to global rotation, in the rigid rotating approximation. We consider a generic process involving qua…

Anisotropic Photon and Dilepton Yield in a Thermalized Quark-Gluon Plasma under Magnetic Fluctuations

Jorge David Castaño-Yepes, Enrique Muñoz

In this article, we analyze the effects of stochastic magnetic fluctuations with respect to an intense magnetic field background over the yields for photon and dilepton emission pr…

Strongly interacting matter in extreme magnetic fields

Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58

Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…

Fermion Self-Energy and Effective Mass in a Noisy Magnetic Background

Jorge David Castaño-Yepes, Enrique Muñoz

In this article, we consider the propagation of QED fermions in the presence of a classical background magnetic field with white-noise stochastic fluctuations. The effects of the m…
