Description
We investigate vector-like fermionic dark matter and flavor anomalies in a simple extension of standard model, 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 vector-like lepton singlet 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. We utilize the bounds from electroweak precision observables and also 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 estimate the branching ratios of the rare lepton flavor violating $\tau$ decays such as $\tau \to \mu (\gamma, \phi, \eta, \eta^\prime)$.
