Thermal effects in freeze-in neutrino dark matter production
A. Abada, G. Arcadi, M. Lucente +2
We present a detailed study of the production of dark matter in the form of a sterile neutrino via freeze-in from decays of heavy right-handed neutrinos. Our treatment accounts for…
Running effects on QCD axion phenomenology
Luca Di Luzio, Maurizio Giannotti, Federico Mescia +3
We study the impact of renormalization group effects on QCD axion phenomenology. Focusing on the DFSZ model, we argue that the relevance of running effects for the axion couplings…
Revisiting decays in the Standard Model and beyond
Damir Bečirević, Gioacchino Piazza, Olcyr Sumensari
In this letter we revisit the Standard Model predictions for and discuss the opportunities that open up when combining its partial decay rate w…
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…
Gauged Inverse Seesaw from Dark Matter
Asmaa Abada, Nicolás Bernal, Antonio E. Cárcamo Hernández +2
We propose an economical model addressing the generation of the Inverse Seesaw mechanism from the spontaneous breaking of a local , with the Majorana masses of the ster…
A new photometric and dynamical study of the eclipsing binary star HW Virginis
S. B. Brown-Sevilla, V. Nascimbeni, L. Borsato +12
A growing number of eclipsing binary systems of the "HW Vir" kind (i. e., composed by a subdwarf-B/O primary star and an M dwarf secondary) show variations in their orbital period,…
Breakdown of chiral perturbation theory for the axion hot dark matter bound
Luca Di Luzio, Guido Martinelli, Gioacchino Piazza
We show that the commonly adopted hot dark matter (HDM) bound on the axion mass 1 eV is not reliable, since it is obtained by extrapolating the chiral expansion in a…
