    • File:Van Hove paper.pdf
    • File:Download3-detail.pdf(more details)

01/14/15

• Discuss status of Omega , Eta and pKK g12 analysis.
• Plans for studies of the use of Linear Polarization in PWA.
• AOB

Minutes People: Carlos, Diane, Will, Paul, Simon, Olga, Igor

omega

• fixing comparison with Igor’s theory
  • talked to Adam
  • correct model for acceptance
  • Carlos wants to correct data and compare to data
• using Q factor to correct for bg
• g12 - unpolarized
  • < 3.6 GeV FSU
  • > 3.6 GeV Carlos
• g13
  • Olga - polarized data, circular (2.6 GeV beam) and linear (80% pol in coherent peak), unpolarized target, Deuteron
  • goal to find spin density matrix
  • problems with fermi motion
• Brian Vernarsky - https://www.jlab.org/Hall-B/general/thesis/Vernarsky_thesis.pdf
• compare normal PWA production factors to Igor’s calculated f
  • instead of comparing Dalitz plot
  • appendix to clas12 proposal uses Adam’s generator (PR12-11-005)
• test pyPWA
  • using real data from Hall D
    • channels?
      • p rho (tons of data already)
      • n 3pi
      • eta pi
      • p 3pi
    • use Metropolis method, weigh MC
      • efficiency, speed?

eta

• Diane
  • finishing theory paper
  • need g12 note done and accepted by collaboration to finish eta -> 3pi analysis
  • going to work with Hall D JEF group with new amplitudes

pkk

• Carlos & Diane
  • pKK PWA
• FIU
  • apply JPAC amplitudes to pK PWA (as of JPAC workshop update)
• Hall D
  • baryon and meson overlap

pyPWA update

• documentation in progress and optimizing
• on JLab github
