Contrasting Pseudoscalar Higgs and Toponium States at the LHC and Beyond
Abdelhak Djouadi, John Ellis, Jeremie Quevillon
We discuss ways to discriminate at hadron colliders between a quasi-bound toponium state and a pseudoscalar Higgs boson A, as predicted in many extensions of the Standard Model. We…
Linear Standard Model extensions in the SMEFT at one loop and Tera-Z
John Gargalionis, Jérémie Quevillon, Pham Ngoc Hoa Vuong +1
Linear Standard Model (SM) extensions, defined as new particles that can couple linearly to SM fields, form a motivated and finite set of simplified models for exploring phenomenol…
Interference Effects in Beyond Leading Order
Federico Buccioni, Federica Devoto, Abdelhak Djouadi +3
The ATLAS and CMS collaborations at the LHC have recently announced evidence for the rare Higgs boson decay into a boson and a photon. We analyze the interference between the p…
New Directions for ALP Searches Combining Nuclear Reactors and Haloscopes
Fernando Arias-Aragón, Vedran Brdar, Jérémie Quevillon
In this work we propose reactoscope, a novel experimental setup for axion-like particle (ALP) searches. Nuclear reactors produce a copious number of photons, a fraction of which co…
Trace Anomaly of Weyl Fermions via the Path Integral
Rémy Larue, Jérémie Quevillon, Roman Zwicky
We compute the trace, diffeomorphism and Lorentz anomalies of a free Weyl fermion in a gravitational background field by path integral methods. This is achieved by regularising the…
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…
