Model-independent analysis on $$R(K^{(*)})$$

We analyze the lepton universality violating $$B\rightarrow K^{(*)}\ell ^+\ell ^-$$ puzzle $$R(K^{(*)})$$ in a model-independent way. The branching ratio $$\mathrm{Br}(B_s\rightarrow \mu ^+\mu ^-)$$ is also considered as main constraint. show how restricts allowed region of parameter space, and investigate new physics effects on electronic well muonic sector . Within reasonable range parameters, we find that scale goes up to $$\sim 5$$ TeV, Wilson coefficient are $$-1\lesssim C_{9NP}^\mu \lesssim 0$$
