Spin-1/2 particles with temperature-dependent and acceleration-dependent magnetic moment

  • C. Massa
Note Brevi


The five-dimensional Kaluza-Klein field theory requires that any spin-1/2 particle has an anomalous magnetic moment μ proportional to the gravitational constantG. A variety of gauge theories requiresG to be temperature dependent, therefore I suggest that μ may be temperature dependent. Since any observer with proper accelerationA perceives himself as immersed in a radiation field of temperatureT proportional toA, the magnetic moment of a spin-1/2 particle may be acceleration dependent. There is a maximal acceleration and also a maximal temperature. Contrary to the opinion expressed by some, a thermal radiation never attains sufficient temperature to enter the antigravity (G<0) regime.
