Decaying spin-3/2 dark matter from baryon number violation
Francesco Costa, Gabriel M. Salla
We explore an uncharted corner of dark matter phenomenology: non-supersymmetric spin- dark matter with baryon number violating interactions. In an effective field theory descr…
The effects of non Bunch-Davies initial conditions on gravitationally produced relics
Enrico Bertuzzo, Gabriel M. Salla, Andrea Tesi
Typical gravitational production of relics from amplification of inflationary perturbations assumes Bunch-Davies initial conditions, i.e. a vacuum with initially no particles. In t…
Could a Primordial Black Hole Explosion Explain the extremely high-energy KM3NeT neutrino Event?
Lua F. T. Airoldi, Gustavo F. S. Alves, Yuber F. Perez-Gonzalez +2
A black hole is expected to end its lifetime in a cataclysmic runaway burst of Hawking radiation, emitting all Standard Model particles with ultra-high energies. Thus, the explosio…
Chasing Serendipity: Tackling Transient Sources with Neutrino Telescopes
Lua F. T. Airoldi, Gustavo F. S. Alves, Yuber F. Perez-Gonzalez +2
The discovery of ultra-high-energy neutrinos by IceCube marked the beginning of neutrino astronomy. Yet, the origin and production mechanisms of these neutrinos remain an open ques…
Spontaneous breaking of baryon number, baryogenesis and the bajoron
Pedro Bittar, Gustavo Burdman, Gabriel M. Salla
We explore the spontaneous breaking of global baryon number for baryogenesis. We introduce a model with three majorana fermions and a complex scalar carrying baryon number charge.…
A log story short: running contributions to radiative Higgs decays in the SMEFT
Christophe Grojean, Guilherme Guedes, Jasper Roosmale Nepveu +1
We investigate the renormalization of the radiative decays of the Higgs to two gauge bosons in the Standard Model Effective Field Theory at mass dimension eight. Given that these a…
Gravitationally produced Dark Matter and primordial black holes
Enrico Bertuzzo, Yuber F. Perez-Gonzalez, Gabriel M. Salla +1
We examine how the existence of a population of primordial black holes (PBHs) influences cosmological gravitational particle production (CGPP) for spin-0 and spin-1 particles. In a…
ALPs, the on-shell way
Enrico Bertuzzo, Christophe Grojean, Gabriel M. Salla
We study how the coupling between axion-like particles (ALPs) and matter can be obtained at the level of on-shell scattering amplitudes. We identify three conditions that allow us…
(In)Visible signatures of the minimal dark abelian gauge sector
Ana Luisa Foguel, Gabriel M. Salla, Renata Zukanovich Funchal
In this paper we study the present and future sensitivities of the rare meson decay facilities KOTO, LHCb and Belle II to a light dark sector of the minimal dark abelian gauge symm…
Characterising Dark Matter-induced neutrino potentials
Gabriel M. Salla
In this paper we explore interactions between neutrinos and Dark Matter. In particular, we study how the propagation of astrophysical neutrinos can be modified by computing the mos…
New Limits on Leptophilic Axionlike Particles and Majorons from ArgoNeuT
Enrico Bertuzzo, Ana Luisa Foguel, Gabriel M. Salla +1
Axionlike particles are among the most studied extensions of the standard model. In this Letter we study the bounds that the ArgoNeuT experiment can put on the parameter space of t…
Dark Photon bounds in the dark EFT
Daniele Barducci, Enrico Bertuzzo, Giovanni Grilli di Cortona +1
Dark photons are massive abelian gauge bosons that interact with ordinary photons via a kinetic mixing with the hypercharge field strength tensor. This theory is probed by a variet…
An on-shell approach to neutrino oscillations
Gustavo F. S. Alves, Enrico Bertuzzo, Gabriel M. Salla
In the usual quantum field theoretical approach, neutrino oscillations are studied diagonalising either the mass or matter Hamiltonians. In this paper we analyse the problem from a…
