Cosmic Neutrinos as a Window to Departures from Special Relativity Carmona Martínez, José Manuel Cortés Azcoiti, José Luis Relancio Martínez, José Javier Reyes Hung, Maykoll Anthonny Quantum gravity Lorentz Invariance Violation Doubly Special Relativity Cosmological neutrinos Ultra-high-energy cosmic rays Física Matemáticas Physics Mathematics We review the peculiarities that make neutrinos very special cosmic messengers in highenergy astrophysics, and, in particular, to provide possible indications of deviations from special relativity, as it is suggested theoretically by quantum gravity models. In this respect, we examine the effects that one could expect in the production, propagation, and detection of neutrinos, not only in the well-studied scenario of Lorentz Invariance Violation, but also in models which maintain, but deform, the relativity principle, such as those considered in the framework of Doubly Special Relativity. We discuss the challenges and the promising future prospects offered by this phenomenological window to physics beyond special relativity.
