Neutrinos as probes for quantum gravity

Abstract

Studying the Planck-scale structure of spacetime is essential for formulating a complete theory of Quantum Gravity. In this context various models predict phenomenological testable scenarios. All these models share the prediction that QG residual effects may manifest as small perturbations of the particle kinematics. The ideal framework for conducting this research is the astroparticle sector due to the high energies and long propagatio path that allow for the accumulation of the supposed tiny QG perturbations. Neutrinos emerge as ideal candidates since they offer different combinations of energies and baselines. Moreover, these particles interact weakly and can propagate for cosmic distances, offering advantages in pointing to the sources.
