One of the central unresolved questions in fundamental physics revolves around the postulated quantum structure of spacetime. Novel physical phenomena are expected as residual evidence of a more fundamental theory of nature. A critical aspect pertains to scrutinizing the hypothesized quantum structure of spacetime at the Planck’s scale and the related departures from the Lorentz symmetry, which currently underpins our comprehension of the natural world. Neutrinos are ideal candidates to explore the hypothesized structure of spacetime at the Planck scale. These particles, in fact, can propagate over cosmological distances without interacting. Moreover, they are not influenced by magnetic fields during propagation, and by reconstructing their direction of origin, it is relatively simple to identify their sources.
In neutrino sector the supposed QG effects can modify the time of flight of astrophysical particles. These correction can affect the time of flight and can modify the usual oscillation pattern introducing species depending perturbations. In this work the interplay between neutrinos and quantum gravity (QG) is investigated, illustrating some proposals about the use of these particles as probes for the supposed quantized structure of spacetime.
