Neutrino Oscillation in a Minimal Length Spacetime

ABSTRACT We investigate how neutrino oscillations are modified in a non‐commutative spacetime characterized by a minimal length scale, described by the Quesne–Tkachuk algebra. By incorporating the algebra's deformation parameter into the effective neutrino mass, we derive the two...

The Gravitational Mass of the Rarefied Cloud of the Relativistic Massive Particles

A cloud of relativistic material particles is studied, the gravitational interaction between which can be neglected. The gravitational mass of the cloud is determined for the region where it can be considered as a point body. The analogy with Newtonian gravity was investigated us...
