Namely, one may treat $θ$ as a universal constant, responsible for correction to the Coulomb and Newton laws, allowing direct interaction between electrical charges and masses.4p, ReVTeX 3.0, no figures, minor correctionsQuantum PhysicsGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
