Next-To-Leading Logarithmic Results in $B\to X_s\gamma$

Abstract

We give a brief review of the next-to-leading logarithmic results in $B\to X_s\gamma$. Combining the results of different groups, a practically complete next-to-leading-logarithmic prediction of the inclusive decay rate was recently presented. The theoretical uncertainty in the decay rate in now less than half of the error in the previously leading-logarithmic result. Therefore, the inclusive $B\to X_s\gamma$ mode will provide important tests of the SM and its extensions when more precise experimental data is available.
