[d2n-analysis-talk] E vs P for Positrons:

[Matthew R. Posik]

Hi Gregg,

   Here is a 2d plot of the energy vs momentum for a few of our positive
polarity runs, looking at positrons (bend-up particles in the BigBite for
positive polarity). This plot has all of our cuts applied except for the E/p
cut. This looks very much like our negative polarity E vs p plots.
