- Start reading from page 161 Chapter Photon Energy Correction. As I stated in the past to Moskov and others, the reason invariant masses involving the final state EC photon have broader widths than the missing mass spectrum is due to a correction needed to the EC calculation on the photon momentum. I had derived a correction factor for g12 and stated to Gagik and Moskov on several occasions that g11 data stream should have a correction to its EC photon. To my knowledge no g11 analysis has a correction to the EC photon because g11 analyses employ kinematic fitting, which if the EC photon is used, the g11 fitter has the correction for it. The thesis I attach is supplemental proof that my hypothesis is correct and if the final state photon is used in ANY manner, such as Georgies case, this correction must be understood and used.
