In this respect, we examine theeffects that one could expect in the production, propagation, and detection of neutrinos, not only in thewell-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. Wediscuss the challenges and the promising future prospects offered by this phenomenological windowto physics beyond special relativity.
