These pages contain an overview of the Radiative corrections studies that have been performed for the B to hh analysis.

The study of B to hh decays cannot avoid the careful evaluation of what is the contribution of radiative corrections. Every decay can be regarded as a B to hh + nphotos decay where the nphotons have not been detected because of some intrinsic lower energy detector threshold. So, when to quote BRs, a careful study needs to be made in order to extract the B to hh BR from the BR (B to hh + nphotons) one. Links to documentation are given below where: QED corrections for B to hh decays have been evaluated, and an overview of the difficulties foreseen in evaluating experimentally what the corrections are is presented.

- QEDcorr.pdf: QED corrections calculation (for B to hh) from E. Baracchini and G.Isidori
- Was.pdf: Talk on PHOTOS implementation of radiative corrections to B decays

There's currently an attempt to understand how PHOTOS is implemented in LHCb software and to understand how to tune it in order to have a correct description of radiative corrections.
