Anomaly in Bottom-Flavored Physics―What is Known and Unknown 10 Years after the First Announcement

Abstract

Large discrepancies in bottom-flavored physics have motivated intensive phenomenological studies for more than ten years. 3–4σ discrepancies between the experimental value and the prediction of the Standard Model (SM) of particle physics in b→cτν and b→sll transitions would imply new particles at TeV scale. In this commentary, we summarize the progress of these 10 years in the SM prediction and new physics interpretation of these hints. We discussed how to find the smoking gun signals of those particles in other bottomquark flavored observables, the large hadron collider, and electric dipole moments. We see that near future data will judge the interpretations by physics beyond the SM.
