Revision as of 09:32, 10 May 2016

Purpose

  1. To give an overview of hadron spectroscopy, with a focus on physics analysis opportunities with Jefferson Lab experimental data.
  2. To discuss software and analysis techniques that will be essential in extracting first physics results from GlueX data.
  3. To have hands-on sessions for participants to actively engage in performing physics analyses.
    • Specifically, a simulated analysis of polarization observables and spin-density matrix elements (SDMEs) of γp→ωp
  • These talks, tutorials, and hands-on sessions will be catered towards graduate students to help familiarize them with doing physics analyses with Jefferson Lab experimental data.

Location and Time

The workshop will take place at:

DATES: May 11 - 13, 2016

LOCATION: CEBAF Center L102 - L104

2013 GlueX Analysis Workshop

  • We conducted a similar workshop back in 2013, doing a simulated full analysis of γp→π+π+π-n. It covered the software and analysis steps necessary to do an amplitude analysis of this channel, from signal generation through amplitude fitting.
  • It is not necessary to have gone through the 2013 workshop talks and exercises to attend the 2016 workshop. However, you will probably benefit if you do, as certain topics will not be covered (e.g. How to do a GlueX simulation) and others will be condensed (e.g. Doing an analysis in JANA).

Student Travel Support

  • We have $3.5k in funding to help defray the travel expenses for students to come to the workshop, that may not have been able to come otherwise.
  • If you are a student (and a JLab user) and would like to apply for travel support, please send an email to Paul Mattione (pmatt@jlab.org) by March 7th with the following information:
    1. Your name and institution
    2. A breakdown of your estimated travel and lodging costs (not meals).
    3. One short paragraph on your current or future GlueX physics analysis plans (not looking for an abstract, just want to know what you're interested in).
  • Funding is limited, but we'll try to help as many students as we can.
