We discuss the implications of the recently reported and anomalies, the lepton flavor non-universality in the and decay channels. Using two sets of hadronic inputs of form factors, we perform a fit of new physics to the and data, and significant new physics contributions are found. We suggest the study of lepton flavor universality in a number of related rare and decay channels, and in particular we give predictions for the -to-e ratios of decay widths with different polarizations of the final state particles, and of the processes, which are presumably more sensitive to the structure of the underlying new physics. With the new physics contributions embedded in the Wilson coefficients, we present theoretical predictions for lepton flavor non-universality in these processes.
