Ideas for Physics Projects (Fall 2011)

Ideas for Physics Projects:

(1) Goodness of fit in PWA

 -- How does one evaluate a goodness of fit in a partial wave analysis?
 -- Performing studies using GlueX MC would prepare us for this question when it arises during data analysis.
 -- This paper by Mike Williams is a good starting point:
      http://arxiv.org/abs/1006.3019

(2) Beam polarization and PWA

 -- How much analyzing power can we gain with precise polarization measurements?
 -- Are there physics channels that rely heavily on polarization?
 -- How do we incorporate the polarization uncertainty into the fits?
 -- Jake has done studies with 0 to 100% polarization in 3pi.  This could be a place to start since the amplitudes are already written.

(3) PWA with multiple tagger hits

 -- How do we handle multiple tagger hits when doing a PWA?  Do we use a weighting scheme?
 -- Richard has some experience with this.  Perhaps Igor could incorporate studies like this into his b1pi analysis?

(4) MC event generators

 -- Do we need more development work on MC event generators?
 -- IUAmpTools does importance sampling on generated mass distributions -- could this be extended?
 -- Does pythia need any more tuning?
 -- etc.
