CKM determination from $W$ decays with jet flavor tagging at CEPC

Zhao-Ling Zhang, Li-Bo Liao, Jia-Rong Li +3

This study investigates the sensitivity of the CEPC to CKM matrix elements $|V_{ij}|$ in semileptonic $W$-pair decays using simulated $e^{+}{e}^{-}\to W^{+}{W}^{-}\to \mu \nu \bar{q}{q}^{\prime }$ samp…
