Neutrino Energy Loss Rates in 3-3-1 Models

Abstract

The stellar energy-loss rates Q due to the production of neutrino pair in the framework of 3-3-1 models are presented. The energy loss rate Q is evaluated for different values of3 in which β is a parameter used to define the charge operator in the 3-3-1 models. The correction to the rate which is compared with that of the Standard Model (δQ) is also evaluated. We show that the correction does not exceed 14% and gets the highest withThe contribution of dipole moment to the energy loss rate is small compared to the contribution of new natural gauge boson Z and this sets constraints for the mass of Z' m Z ≤ 4000GeV. This mass range is within the searching range for Z boson at LHC.

Systematic study of the $SU(3)_c\otimes SU(3)_L\otimes U(1)_X$ local gauge symmetry

“…has not been able enough to provide explanation for several fundamental issues, among them: the hierarchical masses and the mixing angles for both, the quark and the lepton sectors [2][3][4][5][6], charge quantization [7,8,[8][9][10][11][12], the strong CP violation [13][14][15][16], the small neutrino masses and their oscillations [17,18], and last but not least, the presence of dark matter and dark energy in the universe [19][20][21][22][23]. Because of this, many physicists believe that the SM does not stand for the final theory, representing only an effective model originated from a more fundamental one.…”
