“…From a more theoretical perspective, neutrino physics has been proposed as a test bench for the predictions of torsion gravity models [34]. Furthermore, extended models of gravity [35][36][37][38][39] and exotic geometry frameworks can also be tested in the context of this physical sector.…”

In this paper, we aim to explore the interplay between neutrinos and quantum gravity, illustrating some proposals about the use of these particles as probes for the supposed quantized structure of spacetime. The residual signatures of a more fundamental quantum gravity theory can manifest themselves modifying the free particle dispersion relations and the connected velocity. In neutrino sector these supposed eﬀects can modify the time of ﬂight for astrophysical particles with diﬀerent energies and can aﬀect the usual neutrino oscillation pattern introducing species depending perturbations. As a ﬁnal point, we will highlight how perturbations caused by non-standard interactions in the solar neutrino sector can mimic those caused by presumed quantum gravity eﬀects. In fact, the mathematical formulation of non-stadard interactions is equivalent to that of CPT-odd perturbations. We will, therefore, emphasize the need to identify the nature of diﬀerent contributions in order to disentangle them in the search for quantum gravity eﬀects. By reviewing current experimental constraints and observations, we seek to shed light on the intricate relationship between neutrinos and quantum gravity, and discuss the challenges and future directions in this fascinating ﬁeld of research.
