New Strategies for New Physics Search with $\hat{I}{›}_b\to \hat{I}›\hat{I}½\bar{\hat{I}}½$ Decays

We examine the new physics sensitivity of the rare decay $\hat{I}{›}_b\to \hat{I}›\hat{I}½\bar{\hat{I}}½$ which can be accessible at future $Z$-pole machines like FCC-ee and CEPC. We find that the longitudin…
