Tests of Standard Model in leptonic sector and R
We describe the current status of a few tests of the Standard Model using high-precision measurements in the leptonic sector. In particular, lepton universality after recent measurements of the τ lepton mass as well as muon anomalous magnetic moment are discussed. Also reported are recent measurements of the R value in the charmonium and bottomonium energy ranges.
