“…All above studies, the photon is taken ordinary photon. As regards ordinary photon this process is supposed to play an important role for the low density ρ/µ e = 10 5 gr/cm 3 and comparatively low temperature T = 4 • 10 8 K. These calculation has been done for about sixty years ago by many authors in V − A model [1][2][3], SM [4][5][6][7][8][9][10][11][12] and magnetic model [13]. Dutta et al [10,11] considered instead of ordinary photon the massive photon (plasmon) and the angular dependence of the emitted neutrinos for this process in hot and dense matter.…”

Using the minimal extension of Standard Model taking into account the charge radius and the anapole moments of neutrino, we have derived analytic expressions for the stellar energy loss rates due to the production of the neutrino pair process e − +γ → e − +νe+νe in a hot plasma for three limiting regimes (nondegenerate, intermediate and degenerate electrons) of temperature, the electron's chemical potential and plasma's energy. Obtained results show that there is approximately extra 10% contribution by using the considered calculations.

Using the minimal extension of Standard Model taking into account the charge radius and the anapole moments of neutrino, we have derived analytic expressions for the stellar energy loss rates due to the production of the neutrino pair process $e^- + \gamma \rightarrow e^- + \nu_e +\overline{\nu_e}$ in a hot plasma for three limiting regimes (nondegenerate, intermediate and degenerate electrons) of temperature, the electron's chemical potential and plasma's energy. Obtained results show that there is approximately extra $10\%$ contribution by using the considered calculations.

An elementary-particle picture developed primarily by Barut as an alternative to the standard model is re-examined. This model is formulated on the basis of strong short-range magnetic interactions among the stable particles (p, e , v) and at present is able to account qualitatively for most of the known phenomena.For more than three decades high-energy physicists have labored to assemble a wealth of data into a modern picture of elementary particles. The result, described principally in terms of quantum field theory (QFT), is a body of conventional wisdom generally referred to as the standard model. This development has not proceeded without reasoned disagreement, however, and a parallel body of other views exists, which have been less successful in reaching fruition. In particular, the work of Asim Barut and colleagues has aimed to construct a more transparent theory of particles that avoids their instantaneous appearance from, and disappearance into, the vacuum--and which abjures the introduction of new forces in a picture already unified by the electromagnetic field. Guided by a penchant for simplicity and a vision of "the way it ought to be", Barut has provided the skeletal structure for an alternative picture that actually turns out to have a measure of flesh on it. The time seems quite appropriate to gather together and review the essential features of these alternate views, due primarily to one who is very definitely a nonstandard model himself.
