  We outline the confluence of three novel theoretical fields in our modeling
of Gamma-Ray Bursts (GRBs): 1) the ultrarelativistic regime of a shock front
expanding with a Lorentz gamma factor $\sim 300$; 2) the quantum vacuum
polarization process leading to an electron-positron plasma originating the
shock front; and 3) the general relativistic process of energy extraction from
a black hole originating the vacuum polarization process. There are two
different classes of GRBs: the long GRBs and the short GRBs. We here address
the issue of the long GRBs. [...] We are specially interested, in this report,
to a subclass of long GRBs which appear to be accompanied by a supernova
explosion. We are considering two specific examples: GRB980425/SN1998bw and
GRB030329/SN2003dh [...].
