Measurement of Forward-Backward Asymmetry in $B\to K^{(*)}\mu\mu$ and Search for $B_s^0\to \phi\mu\mu$ at the CDF Experiment

We report results on the measurement of the forward-backward asymmetry ($A_{\rm FB}$) in $B\to K^{(*)}\mu\mu$. $A_{\rm FB}$ may imply new physics beyond the standard model via the loop structure in the decay. The data set is collected with the CDF II detector using $p\bar{p}$ collisions produced at the Fermilab Tevatron. $A_{\rm FB}$ is extracted from a muon angular distribution in dimuon restframe. We also present a search result for $B_s^0\to \phi\mu\mu$ that is not observed so far.
