How well can the QCD axion hide?
Sung Mook Lee, Maria Ramos, Fuensanta Vilches
Motivated UV frameworks generically predict the existence of multiple axion fields. Their interplay gives rise to novel collective phenomena - including level crossings and the for…
Reconstructing a Heavy Neutral Lepton at the LHC
Pablo de la Torre, Manuel Masip, Fuensanta Vilches
Heavy lepton singlets slightly mixed with a standard neutrino are usually searched for at the LHC in the trilepton plus channel: $pp \to W^+ \t…
Automation of a Matching On-Shell Calculator
Javier López Miras, Fuensanta Vilches
We introduce , a package designed to facilitate on-shell calculations in effective field theories (EFTs). This initial release focuses on the…
Efficient on-shell matching
Mikael Chala, Javier López Miras, José Santiago +1
We propose an efficient method to perform on-shell matching calculations in effective field theories. The standard off-shell approach to matching requires the use of a Green's basi…
Renormalization of the SMEFT to dimension eight: Fermionic interactions I
S. D. Bakshi, M. Chala, Ã. DÃaz-Carmona +2
This is the third of a series of works (arxiv:2106.05291, arxiv:2205.03301) aimed at renormalizing the Standard Model effective field theory at one loop and to order , with…
