Boiling away asymmetries: low-scale phase transitions, gravitational waves and leptogenesis
Leonardo Grimaldi, Michele Lucente, Silvia Pascoli
Leptogenesis is one of the most popular mechanisms to account for the observed baryon asymmetry of the Universe. A generic feature of leptogenesis is a large separation of scales b…
Global fits and the search for new physics: past, present and future
Peter Athron, Csaba Balázs, Jon Butterworth +15
In this work, we review the history and current role of global fits in the search for physics beyond the Standard Model~(BSM), including precision tests of the Standard Model (SM).…
Supercooled Dark Scalar Phase Transitions explanation of NANOGrav data
Francesco Costa, Jaime Hoefken Zink, Michele Lucente +2
The evidence of a Stochastic Gravitational Wave Background (SGWB) in the nHz frequency range is posed to open a new window on the Universe. A preferred explanation relies on a supe…
ELENA: a software for fast and precise computation of first order phase transitions and gravitational waves production in particle physics models
Francesco Costa, Jaime Hoefken Zink, Michele Lucente +2
We present ELENA (EvaLuator of tunnElliNg Actions), an open-source Python package designed to compute the full evolution of first-order phase transitions in the early Universe gene…
Testable dark matter solution within the seesaw mechanism
A. Abada, G. Arcadi, M. Lucente +1
The presence of a dark matter component in the Universe, together with the discovery of neutrino masses from the observation of the oscillation phenomenon, represents one of the mo…
From oversimplified to overlooked: the case for exploring Rich Dark Sectors
Asli Abdullahi, Francesco Costa, Andrea Giovanni De Marchi +9
The Standard Model (SM) of particle physics provides a very successful description of fundamental particles and their interactions but it is incomplete, as neutrino masses, dark ma…
