Abstract (SpringerLink, EDP Sciences, SAO/NASA ADS, Refdoc)
The dispersion relations of superluminal wave propagation in electron plasmas are derived, and the tachyonic energy flux, the velocity of energy transport, and the relaxation time asymptotics of the conductivity are studied. The formalism is based on Maxwelltype equations for Proca fields with negative masssquare in dispersive and dissipative media. Specifically, superluminal radiation fields generated by the ultrarelativistic electronic source plasma of γray bursts (GRBs) are investigated. The radiation field is coupled to the shockheated electron gas by a frequencydependent finestructure constant. The varying coupling constant generates longrange dispersion in the charge and current densities. At high energy, the coupling strength approaches a finite limit, so that the Proca field becomes minimally coupled to the electron current. The tachyonic finestructure constant scales with the frequencydependent superluminal velocity of the radiated modes. This scaling is manifested in the tachyonic flux densities of the GRB plasma, so that the scaling exponent can be extracted from spectral maps in the soft γray band. To this end, tachyonic spectral fits of GRB 930506, GRB 950425, and GRB 910503 are performed. The scaling amplitude of the finestructure constant is inferred from the burst duration. The transversal and longitudinal tachyonic luminosity of the source plasma is calculated in the hightemperature regime. Estimates of the plasma temperature and the internal energy of the ultrarelativistic electron gas are obtained.
