[Halld-physics] Physics Meeting on Monday

Hi Volker,

I will probably be working more on the strangeness S=-1
channels than the S=-2 channels in the immediate future.
This has the advantage that there are less final state
particles and I can focus on how good the reconstruction
is for vertices etc. I think this will also benefit the
reconstruction code, since it will be easier to isolate
where the difficulty is with simpler event topologies.

I will give updates as things progress at the meetings.

If we all start taking a look at them (with the ANALYSIS library, the BDT, and AmpTools), we can learn about the performance/ability of the GlueX detector to isolate these channels, and what the remaining backgrounds might be.

This would be a huge step towards getting us ready to analyze the experimental data when it comes in.
