In the family grand unification models (fGUTs), we propose that gauge U(1)s beyond the minimal GUT gauge group are family gauge symmetries. For the symmetry $L_mu-L_tau$, i.e. $Q_{2}-Q_{3}$ in our case, to be useful for the LHC anomaly, we discuss an SU(9) fGUT and also present an example in Georgis SU(11) fGUT.
We discuss the feasibility of detecting the gauge boson of the $U(1)_{L_{mu}-L_{tau}}$ symmetry, which possesses a mass in the range between MeV and GeV, at the Belle-II experiment. The kinetic mixing between the new gauge boson $Z$ and photon is for
Positron excess upto energies $sim$350 GeV has been observed by AMS-02 result and it is consistent with the positron excess observed by PAMELA upto 100 GeV. There is no observed excess of anti-protons over the expected CR background. We propose a lep
We investigate Majorana dark matter in a new variant of $U(1)_{L_{mu}-L_{tau}}$ gauge extension of Standard Model, containing three additional neutral fermions $N_{e}, N_{mu}, N_{tau}$, along with a $(bar{3},1,1/3)$ scalar Leptoquark (SLQ) and an ine
The tightening of the constraints on the standard thermal WIMP scenario has forced physicists to propose alternative dark matter (DM) models. One of the most popular alternate explanations of the origin of DM is the non-thermal production of DM via f
We propose an anomaly free unified scenario by invocation of an extra local ${rm U(1)}_{L_{mu}-L_{tau}}$ gauge symmetry. This scenario simultaneously resolves the $R_{K^{(*)}}$ anomalies, the dark matter puzzle and the long-standing discrepancy in mu
