Dark matter and baryogenesis in the Fermi-bounce curvaton mechanism
TL;DR: In this paper, a toy model of matter bounce is presented, in which the matter content is constituted by two fermion species endowed with four Fermion interaction terms, and the curvaton mechanism that is thus generated, and it is argued that one of the two Fermionic species may realize baryogenesis, while the other one is compatible with constraints on extra hot dark matter particles.
Neutron Majorana mass from exotic instantons
Andrea Addazi,Massimo Bianchi +1 more
TL;DR: In this article, the authors show how a Majorana mass for the neutron could result from nonperturbative quantum gravity effects peculiar to string theory, in particular, "exotic instantons" in un-oriented string compactifications with D-branes extending the supersymmetric standard model could indirectly produce an effective operator δm n −24 −10−25 eV.
External Stability for Spherically Symmetric Solutions in Lorentz Breaking Massive Gravity
TL;DR: In this article, the authors analyze the stability of the geodesic equations at the first order (deviation equation) for point-like sources in Lorentz-breaking massive gravity theories.
Resonant graviton-photon transitions with cosmological stochastic magnetic field
Andrea Addazi,Salvatore Capozziello,Qingyu Gan +2 more
TL;DR: Researchers propose a method to detect high-frequency gravitational waves through resonant conversions to radio-signals, amplified by a cosmological stochastic magnetic field, potentially testable with radio telescopes like ARCADE 2 and EDGES.

TL;DR: In this paper , the VIP-2 lead experiment sets the strongest bounds, searching for the Pauli exclusion principle violating atomic transitions in lead, excluding the θ-Poincaré noncommutative quantum gravity models far above the Planck scale for nonvanishing θμν} electriclike components.
