Radiative B-decay as a test of CKM unitarity
We point out that R \equiv Br(b\rightarrow d \gamma)/Br(b\rightarrow s \gamma) is a sensitive probe of possible violation of CKM unitarity. We compute R in a minimal extension of the Standard Model containing an additional isosinglet charge (-1/3) quark, which leads to a deviation from CKM unitarity...
