[Hps-analysis] test pass 7d

[Graf, Norman A.]

Dear Colleagues,

I've posted the results of my first, quick analysis of the tpass7d output to the #project-2015pass7 channel on Slack: https://urldefense.proofpoint.com/v2/url?u=https-3A__heavyphotonsearch.slack.com_messages_C5FCT7161_&d=DwIFAw&c=lz9TcOasaINaaC3U7FbMev2lsutwpI4--09aP8Lu18s&r=J4PP6Zl8IyGHpsqWaKegORCYw8hoCHePTw5O95a5lqQ&m=31KdcHpVRcym8EeuD0kiVBLMaekteJ9TLDj-Dpn7ce0&s=pHQlOW1rCs5qU_BiZQgnapVDA4lNkEk126M2nKalk1E&e=  . So far I have only analyzed the Møller skim from run 5772.

Preliminary conclusions are:


Unconstrained vertex position reconstruction consistent with beamspot centered at (0,0) and a target at z=0.5mm.

Unconstrained vertex momenta show only very small deviations of beam from z axis.

Uniformity of mass calculated from the three vertex collections (Unconstrained, BeamspotConstrained and TargetConstrained) confirms the internal consistency of locating the target at z=0.5mm.

TargetConstrained Møller mass (from a simple Gaussian fit) is

m=0.033276±0.000003

TargetConstrained Møller mass resolution (from a simple Gaussian fit) is

sigma=1.4633E-3 ± 3.0E-6

So far, so good.


Norman
