In this particle physics activity students will be doing the following:

Determining the charge of muons deflected by a magnetic field

Writing a Matlab program to:a. histogram the "raw" data (diagnostic histograms) b. calculate the invariant mass of dimuon pairs c. Lorentz transform the data from the lab frame to the dimuon rest frame and repeat (a and b) in this frame

2. Tuesday HW (5/10)
a. Review the effect of electric field (electric potential difference) on a charged particle; definition of an electron volt (eV) as a unit of energy
b. Review the effect of a uniform magnetic field on a charged particle; review direction of deflection of moving charged particle in a uniform magnetic field; relationship between high momentum and small deflection of a charged particle in a uniform magnetic field
c. Review the relativistic equations of momentum (gam*m*v) and energy (gam*m*c^2); review the relationship between E, p and m; E^2=(p*c)^2+(m*c^2)^2

4. Thursday (5/12) Double Class due to Drama
a. Allocation of Dimuon Events - 5 minutes (if not done Monday)
b. See this link for recommendations on how to count the number of Global Muons: Identifying Global Muons
c. Students: Rate the Dimuon Events Event Display and 2000 Dimuon Events: Meadowview Spreadsheet CHECK EVENT NUMBERS PERIODICALLY

Writing a Matlab Program

5. Monday (5/16)
a. Create Folder Called CMS in your Matlab Folder

b. Students: Copy Text File (Matlab - data read statements & comment statements) into new Matlab script file (DiMuon2016.m) in CMS Folder

This file will be provided once the rating of the dimuon events is complete.

d. Explain Analysis Program
e. Explain Diagnostic Histograms (Recommendation for Layout of Histograms)
f. Students: Start Writing Code for Diagnostic Histograms
g. Explain: Physics of invariant mass (Conservation Laws and Relativity)
h. Students: Homework - continue to write code
i. Explain how to transform the muon 4-momenta with the Lorentz Transformation to the DiMuon rest frame. (Background information on the Lorentz Transformation .
