Testing Dark Matter Models with Radio Telescopes in light of Gravitational Wave Astronomy
Andrea Addazi, Yi-Fu Cai, Antonino Marciano
In this Letter we put forward a novel phenomenological paradigm in which particle physics beyond the Standard Model may be tested by radio astronomy if they are related to a first…
Testing Noncommutative Spacetimes and Violations of the Pauli Exclusion Principle with underground experiments
Andrea Addazi, Pierluigi Belli, Rita Bernabei +1
We propose to deploy limits that arise from different tests of the Pauli Exclusion Principle in order: i) to provide theories of quantum gravity with an experimental guidance; ii)…
Emergent inflation from a Nambu--Jona-Lasinio mechanism in gravity with non-dynamical torsion
Andrea Addazi, Pisin Chen, Antonino Marciano
We discuss how inflation can emerge from a four-fermion interaction induced by torsion. Inflation can arise from coupling torsion to Standard Model fermions, without any need of in…
Science with e-ASTROGAM (A space mission for MeV-GeV gamma-ray astrophysics)
A. De Angelis, V. Tatischeff, I. A. Grenier +248
e-ASTROGAM (enhanced ASTROGAM) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated t…
Evaporation and Antievaporation instabilities
Andrea Addazi, Antonino Marciano
We review (anti)evaporation phenomena within the context of quantum gravity and extended theories of gravity. The (anti)evaporation effect is an instability of the black hole horiz…
Testing merging of Dark Exotic Stars from Gravitational Waves in the Multi-messenger approach
Andrea Addazi, Antonino Marciano
We discuss possible implications of the recent detection by the LIGO and VIRGO collaboration of the gravitational-wave event GW170817, the signal of which is consistent with predic…
Super-light baryphotons, Weak Gravity Conjecture and Exotic instantons in Neutron-Antineutron transitions
Andrea Addazi
In companion papers \cite{Addazi:2015pia,Addazi:2016rgo}, we have discussed current bounds of a new super-light baryo-photon, associated to a gauged, from neutron-anti…
Gravitino and Polonyi production in supergravity
Andrea Addazi, Sergei V. Ketov, Maxim Yu. Khlopov
We study production of gravitino and Polonyi particles in the minimal Starobinsky-Polonyi supergravity with inflaton belonging to a massive vector supermultiplet. O…
Evaporation/Antievaporation and energy conditions in alternative gravity
Andrea Addazi
We discuss the evaporation and antievaporation instabilities of Nariai solution in extended theories of gravity. These phenomena were explicitly shown in several different extensio…
A new duality between Topological M-theory and Loop Quantum Gravity
Andrea Addazi, Antonino Marciano
Inspired by the long wave-length limit of topological M-theory, which re-constructs the theory of D gravity in the self-dual variables' formulation, we conjecture the existenc…
Suppression of Bekenstein-Hawking radiation in -gravity
Andrea Addazi
We discuss semiclassical Nariai black holes in the framework of -gravity. For a diagonal choice of tetrades, stable Nariai metrics can be found, emitting Bekenstein-Hawking r…
Kac-Moody instantons in space-time foam as an alternative solution to the black hole information paradox
Andrea Addazi, Pisin Chen, Antonino Marciano +1
Hawking, Perry and Strominger recently invoked BMS symmetry charges in an attempt to resolve the black hole information paradox. Here we propose an alternative scenario that is bas…
Testing B-violating signatures from Exotic Instantons in future colliders
Andrea Addazi, Xian-Wei Kang, Maxim Yu. Khlopov
We discuss possible implications of Exotic Stringy instantons for Baryon-violating signatures in future colliders. In particular, we discuss high-energy quarks collisions and $Λ-\b…
Evaporation and anti-evaporation instability of a Schwarzschild-de Sitter braneworld: the case of five-dimensional F(R) gravity
Andrea Addazi, Shin'ichi Nojiri, Sergei Odintsov
We study the problem of a four-dimensional brane lying in the five-dimensional degenerate Schwarzschild-de Sitter (Nariai) black hole, in five-dimensional -gravity. We show t…
Limiting Majoron self-interactions from Gravitational waves experiments
Andrea Addazi, Antonino Marciano
We show how Majoron models may be tested/limited in gravitational waves experiments. In particular, the Majoron self-interaction potential may induce a first order phase transition…
Gravitational waves from dark first order phase transitions and dark photons
Andrea Addazi, Antonino Marciano
Cold Dark Matter particles may interact with ordinary particles through a dark photon, which acquires a mass thanks to a spontaneous symmetry breaking mechanism. We discuss a dark…
Dark Matter from Starobinsky Supergravity
Andrea Addazi, Maxim Yu. Khlopov
We review our recent results on dark matter from Starobinsky supergravity. In this context, a natural candidate for Cold Dark Matter is the gravitino. On the other hand, assuming t…
DAMA annual modulation and mirror Dark Matter
R. Cerulli, P. Villar, F. Cappella +5
The DAMA experiment using ultra low background NaI(Tl) crystal scintillators has measured an annual modulation effect in the keV region which satisfies all the peculiarities of an…
Energy conditions in Starobinsky supergravity
Andrea Addazi, Sergei V. Ketov
We consider the classical energy conditions (strong, null and weak) in Starobinsky supergravity theories. We study in detail the simplest Starobinsky supergravity model in the "old…
