B to gamma gamma in an Appelquist-Cheng-Dobrescu model
B to gamma gamma in an Appelquist-Cheng-Dobrescu model
We present a full calculation of the amplitudes for B-d[s] -> gamma gamma in a simple Appelquist-Cheng-Dobrescu model that extends an incomplete one in a previous paper. We find cancellations between the contributions from different Kaluza-Klein towers and a small decrease relative to the standar...

We present a full calculation of the amplitudes for B-d[s] -> gamma gamma in a simple Appelquist-Cheng-Dobrescu model that extends an incomplete one in a previous paper. We find cancellations between the contributions from different Kaluza-Klein towers and a small decrease relative to the standard model predictions. It is conjectured that radiative QCD corrections might actually lead to an enhancement in the branching ratios and CP asymmetries, but no more than modest ones. |
