Description
We make a comprehensive study of vector-like fermionic dark matter and flavor anomalies in a simple extension of standard model. The model is added with doublet vector-like fermions of quark and lepton type, and also a $S_1(\bar{\textbf{3}},\textbf{1},1/3)$ scalar leptoquark. An additional lepton type singlet fermion is included, whose admixture with vector-like lepton doublet plays the role of dark matter and is examined in relic density and direct detection perspective. Electroweak precision observables are computed to put constraint on model parameter space. We constrain the new couplings from the branching ratio and angular observables associated with $b \to sll (\nu_l \bar \nu_l)$, $b \to s \gamma$ decays. We then estimate the branching ratios of the rare lepton flavor vioalting $\tau$ decays such as $\tau \to \mu (\gamma, \phi, \eta, \eta^\prime)$. We also investigate the muon anomalous magnetic moment.
