重力场对 $\kappa$-deformed 空间中的中微子振荡的影响
摘要
In this study, we analyse how quantisation of space-time affects propagating fermions in the presence of gravity. Effect of gravity is incorporated using spin connection which consists of universal torsion-free Levi-Civita connection and the Contortion tensor. This leads to the appearance of a four-fermion interaction term in the Lagrangian and because of non-commutativity of space-time, the deformation of the interaction term is found to depend on the background metric through tetrads. Further, we incorporate this interaction term to see the effect of gravitational interactions of neutrinos with the background matter in non-commutative space-time and study its effect on neutrino oscillation probabilities.
