| contents | We report new constraints on the parameters of $f(T)$ teleparallel gravity, derived from its imprints on neutrino flavor oscillations. Our analysis reveals that the presence of spacetime torsion can alter both vacuum oscillations and the matter enhanced Mikheyev Smirnov Wolfenstein (MSW) resonance. By using data from solar neutrino experiments: Super-Kamiokande, SNO, Borexino, and KamLAND, we perform a combined analysis to place the first direct observational bounds on the neutrino-torsion coupling and $f(T)$ parameters. These results establish neutrino phenomenology as a novel astrophysical probe for testing fundamental modifications of gravity. |
