Open system approach to neutrinos propagating in an ultralight scalar background
Lua F. T. Airoldi, Gustavo F. S. Alves, Pedro A. N. Machado +1
We examine decoherence in neutrino oscillations induced by an ultralight scalar field coupled to neutrinos. The scalar induces time- and position-dependent shifts in the neutrino m…

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…
