[G12] Beam Energy Corrections for All Runs

[Mukesh Saini]

Hi All,

The attached file contains the plots for Beam Energy Corrected Protons from the Missing Mass off of (PiPlus PiMinus).

>From the plot, we can see that the Beam Energy Correction's I have currently, work.

These are a list of numbers, one for each run, and I multiply each event beam photon energy by this factor to get the new beam 4-vector and go on to calculate the MM(pi+pi-) from p pi+ pi- exclusive events.

Protons for most of the Runs, after BEC, have a (Mean) Mass within 0.3 MeV of the actual proton mass.

You can compare these plots with the earlier ones presented at:

Let me know your thoughts and questions,
