Since its inception, no decisive departure from the predictions of Standard\nModel (SM) has been reported. But recently various experiments have observed\nfew hints of possible departure from SM predictions in lepton flavor\nuniversality observables such as RK(*), P5', muon (g-2),\nR(D(*)) etc. Many of these observable where deviation from SM in the range\nof (2-4)\σ were observed are related to muon (\μ) lepton. So these\ndeviations may be some hint of a possible New Physics (NP) in the muon sector.\nIn this work we extend the SM by introducing two SM singlet heavy charged\nleptons (Fe, F\μ) whose left handed components are charged under a\nnew U(1)F gauge symmetry, one color triplet lepto-quark (\φQ)\ndoublet under SU(2)L, one inert Higgs doublet (\φl), three very\nheavy Majorana neutrinos (NiR), all of which are odd under a Z2\ndiscrete symmetry. One more scalar (\φ) charged only under the U(1)F\nwhose VEV give masses to the U(1)F gauge boson as well as the heavy\nleptons. With these new particles, we show that the observed anomalies in the\nmuon sector as well as small neutrino masses can be explained with taking into\naccount all the other experimental and theoretical constrains till date.\n
