About the Workshop

Kinematic fitting is one of the most important tools for analyzing data in hadron physics. This workshop will give an overview about the basic concepts of kinematic fitting, and how this is used in GlueX analysis. The following topics are covered amongst other things:

  • Mathematical background of kinematic fitting
  • Diagnostic tools
  • Implementation in GlueX data analysis

Location and Time

The workshop will take place at:

DATES: Friday, Oct. 22, 2021

LOCATION: ONLINE. (add Zoom link)


  • Basic knowledge in linear algebra
  • Understand core principles of least squares minimization with constraints
  • Familiar with ROOT data analysis
