Minimal SO(10) ante portas: the importance of being effective
Anca Preda, Goran Senjanović, Michael Zantedeschi
The minimal grand unified theory, augmented by higher-dimensional operators, is based on the following Higgs representations: adjoint , spinor and…
Ultralight Black Holes as Sources of High-Energy Particles
Michael Zantedeschi, Luca Visinelli
The \textit{memory burden} effect, the idea that the amount of information stored within a system contributes to its stabilization, is particularly relevant for systems with a larg…
Do neutrinos bend? Consequences of an ultralight gauge field as dark matter
Luca Visinelli, Tsutomu T. Yanagida, Michael Zantedeschi
An ultralight gauge boson could address the missing cosmic dark matter, with its transverse modes contributing to a relevant component of the galactic halo today. We show that, in…
Memory Burden Effect in Black Holes and Solitons: Implications for PBH
Gia Dvali, Juan Sebastián Valbuena-Bermúdez, Michael Zantedeschi
The essence of the \textit{memory burden} effect is that a load of information carried by a system stabilizes it. This universal effect is especially prominent in systems with a hi…
Cavity Detection of Gravitational Waves: Where Do We Stand?
Claudio Gatti, Luca Visinelli, Michael Zantedeschi
High frequency gravitational waves (HFGWs) are predicted in various exotic scenarios involving both cosmological and astrophysical sources. These elusive signals have recently spar…
Minimal SU(5) theory on the edge: the importance of being effective
Goran Senjanović, Michael Zantedeschi
It is well known that the minimal renormalizable grand unified theory is ruled out: it predicts same masses of down quarks and charged leptons, the gauge couplings do not u…
