Revision as of 22:03, 26 January 2016

Purpose

• To give an overview of recent developments in hadron spectroscopy, with a focus on physics analysis opportunities with Jefferson Lab experimental data.
• To discuss software and analysis techniques that will be essential in extracting first physics results from GlueX data.
• To have hands-on sessions for participants to actively engage in performing physics analyses.

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.

Although this workshop is GlueX-focused, its content is of interest to the larger Jefferson Lab hadron spectroscopy community, and all are invited to attend.

Location and Time

The workshop will take place at:

DATES: May 11 - 13, 2016
