[Clas12_verystrange] Very Strange Meeting May 2nd

[dugger at jlab.org]

Hi,

I will not be able to attend the meeting today.

Here is a short note on where I am at:

The Good ->

* I can run the new tree that Shankar produced.

** The PID looks OK (about the same as before)

** There are a lot more events at large angle and low momentum. I assume
these events are coming from CTOF, but have not checked that assumption.

The Bad and the Ugly->

* I tried to do a missing mass for the reaction gamma p -> p X. Get huge
bump at massX squared = - 0.1 . Can't figure out what is going on there.

* The invariant mass of the proton pi^- system is just a blob at masses
that look somewhat high. Just a mess really.

If anyone can get any good looking physics (some sort of invariant mass
peak at about the right location), please let me know. My stuff is just
kind of awful :(

Take care,
Michael
