A lesson from and at Belle II
Arturo de Giorgi, Gioacchino Piazza
Within the assumption of Left-Handed (LH) New Physics (NP), we review the relations between and for sev…
Axion-pion thermalization rate in unitarized NLO chiral perturbation theory
Luca Di Luzio, Jorge Martin Camalich, Guido Martinelli +2
We compute the axion-pion scattering , relevant for the axion thermalization rate in the early universe, within unitarized NLO chiral perturbation theory. The latter ext…
Heavy Neutral Leptons Beyond Simplified Scenarios
Gioacchino Piazza, Asmaa Abada, Pablo Escribano +1
Heavy neutral leptons (HNL) constitute the building blocks of several neutrino mass generation mechanisms. Experimental searches depend on their masses and mixings with the active…
Collider Searches for Heavy Neutral Leptons: beyond simplified scenarios
Asmaa Abada, Pablo Escribano, Xabier Marcano +1
With very few exceptions, the large amount of available experimental bounds on heavy neutral leptons - HNL - have been derived relying on the assumption of the existence of a singl…
decay at next-to-leading order in chiral perturbation theory
Luca Di Luzio, Gioacchino Piazza
We discuss the construction of the two-flavour axion-pion effective Lagrangian at the next-to-leading order (NLO) in chiral perturbation theory and present, as a phenomenological a…
