Novel Bounds From The Weak Gravity and Festina Lente Conjectures
Fayez Abu-Ajamieh, Pratik Chattopadhyay, Nobuchika Okada +2
We demonstrate that the Weak Gravity Conjecture (WGC) and the Festina-Lente Conjecture (FLC) yield novel bounds on fifth force searches and milli-Charged Particles (mCPs), as well…
Gravitational Waves from Dark Gauge Sectors
Alexander Belyaev, Mårten Bertenstam, João Gonçalves +3
We explore gravitational-wave (GW) signatures from a strong first-order phase transition in a non-Abelian dark sector, which naturally gives rise to vector dark matter (DM). We con…
Primordial black holes and magnetic fields in conformal neutrino mass models
Shyam Balaji, João Gonçalves, Danny Marfatia +2
Sufficiently strong and long-lasting first-order phase transitions can produce primordial black holes (PBHs) that contribute substantially to the dark matter abundance of the Unive…
Are there minimal exceptional aGUTs from stable 5D orbifolds?
Giacomo Cacciapaglia, Alan S. Cornell, Aldo Deandrea +4
In analysing five dimensional orbifolds with exceptional gauge groups, we seek to find stable vacua configurations which satisfy the minimal requirements for asymptotic grand unifi…
Gravitational waves from color restoration in a leptoquark model of radiative neutrino masses
Mårten Bertenstam, Marco Finetti, António P. Morais +2
We study the first-order phase transitions and the emerging stochastic gravitational wave spectrum in a minimal leptoquark extension of the Standard Model that explains active neut…
Supercooled phase transitions in conformal dark sectors explain NANOGrav data
João Gonçalves, Danny Marfatia, António P. Morais +1
According to recent lore, it is difficult to explain the evidence for a stochastic gravitational wave background obtained by pulsar timing arrays with supercooled first-order phase…
