[Hps-analysis] HPS Analysis meeting Friday May 6 @ 8am/11am PDT/EDT

[Nelson, Timothy Knight]

I think there might be some structure there from the quantization of crystal positions.

The bigger question is whether this is expected or not.  While one could posit that there might be more accidentals in data (is there background in the MC?) the momentum range where this cutoff occurs isn’t really in the vicinity of FEE momenta.

After drawing the tracks and seeing that they were skimming the edge of our acceptance at the back of the tracker, I simply assumed that the deficit in MC was caused by losing them outside our acceptance.  However, the tracks that are lost are the ones that fall *inside* our 6-layer acceptance.  This is even stranger.
