The Purdue University QuarkNet Center is a group of physicists and teachers who work together to learn about particle physics and how to bring what they learn to the classroom. Mentors Matthew Jones, Daniela Bortoletto, and David Sederberg lead the group along with lead teacher Marla Glover. In spring 2013, the Purdue center sent a physicist, a teacher, and cosmic ray detectors high into the atmosphere in hot air balloons to record the changes in flux. The group is also active in masterclasses and Marla Glover is a QuarkNet LHC fellow.
Description
The Purdue center works on cosmic rays and CMS data.
Geographical distribution of CMS E-Lab uploaded posters and a brief inquiry into the aforementioned distribution and its varied nuances.

J/Psi Mass Re-Evaulation
Our group elected to re-evaluate the conclusions reached by a previous group regarding the mass of a J/Psi particle based on muon +/- and muon ++/-- decays. The previous group concluded that the mass was either 3.05 GeV based on muon +- or 2.48 GeV based on muon ++/-- decay. Our evaluation is attached: http://www.i2u2.org/elab/cms/posters/display.jsp?name=adasf.data

Jpsi refinement
Your group is refining a previous attempt by a group to find the mass of the Jpsi.
J/Psi Mass and Decay Re-Evaluation
Our group discovered a poster which evaluated the mass of a J/Psi particle to be approximately 3.05 GeV/c2. While this agrees with the accepted value of the mass of a J/Psi particle, the graphical representation used to reach this conclusion left much to be desired. We will be re-evaluating the CERN data using a smaller bin width and including data from the MasterClass website.
Just testing
In the group. Good job with the pics to you overachievers.

During the course of this week, the Bomb Squad group collected and analyzed data comparing the count rate and coincidence rate of cosmic rays at varying levels in the Purdue Northwestern Avenue Parking Garage. Our poster of this experiment is available for review. http://www.i2u2.org/elab/cosmic/posters/display.jsp?name=purdue_parking_garage_project.data

Objectives
Workshop participants will:
- Identify particles colliding and emerging from collisions at the LHC from CMS data.
- Interpret the physical meaning of plots created from CMS data in light of conservation rules (energy, momentum, charge).
- Ask and answer questions about the physics of high energy collisions using CMS data.
