Shockwaves and Time Delays in Einstein-Maxwell Effective Field Theory
Christophe Grojean, Minyuan Jiang, Pham Ngoc Hoa Vuong
We derive the shockwave metric in four-dimensional Einstein-Maxwell effective field theory (EFT) by performing an ultra-relativistic boost of the charged black hole solution accomp…
Small instanton-induced flavor invariants and the axion potential
Ravneet Bedi, Tony Gherghetta, Christophe Grojean +3
Small instantons which increase the axion mass due to an appropriate modification of QCD at a UV scale , can also enhance the effect of CP-violating operators to shift…
Quadratic Coupling of the Axion to Photons
Carl Beadle, Sebastian A. R. Ellis, Jérémie Quevillon +1
We show that the QCD axion couples to the electromagnetic kinetic term at one loop. The result is that if axions make up dark matter, they induce temporal variation of the fine str…
Anomalies from an effective field theory perspective
Baptiste Filoche, Rémy Larue, Jérémie Quevillon +1
The path-integral measure of a gauge-invariant fermion theory is transformed under the chiral transformation and leads to an elegant derivation of the anomalous chiral Ward-Takahas…
Axion Effective Action
Jérémie Quevillon, Christopher Smith, Pham Ngoc Hoa Vuong
In this paper, we discuss the construction of Effective Field Theories (EFTs) in which a chiral fermion, charged under both gauge and global symmetries, is integrated out. Inspired…
