👉 In physics and quantum mechanics, a leptoprosopic state is an eigenstate of the Lepton spin operator ψ (spin=1/2) in a closed system. It describes a particle that is characterized by its momentum p = mv for some mass m and velocity v. In other words, a leptoprosopic state is an object with zero rest mass but has a non-zero momentum when it moves through space-time. This means that the total energy of the system is not cons
