PHY 557 
Elementary Particle Physics 
Spring 2017 
Phy557 is an introduction to
Modern Elementary Particle Physics. The course is an overview of the
field. The course will start with the basic particle physics taxonomy.
The basics of field theory required for quantification of relativistic
processes will be introduced. The three well established gauge theories:
QED, QCD and electroweak interactions will be described and the basic
techniques to evaluate cross sections and decay rates for some processes
at first order will be given. The final part of the course will review
the basics of experimental techniques and characteristic examples of
experiments in particle physics.

These are the text books being used to prepare the lectures 
The particle data listings will be useful. It can be accessed online by the students at Particle Data Group

Problem Sets and Grading:
Problem sets will be assigned in class and are due on the date shown. You are expected to solve them on your own and the final calculations handed in must be your own work and must be written by hand . Late homework will not be accepted. The final grade will be based on the homeworks and a final work or exam and a possible midterm exam depending on the number of students registered. 
Any excuses (medical or otherwise) are to be documented, and discussed with the instructors in a timely manner. If you have a physical, psychological, medical or learning disability that may impact on your ability to carry out assigned course work, we urge that you contact the staff in the Disabled Student Services office (DSS), Room 133 Humanities, 6326748/TDD. DSS will review your concerns and determine, with you, what accommodations are necessary and appropriate. All information and documentation of disability is confidential.
ACADEMIC INTEGRITY Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another persons work as your own is always wrong. Any suspected instance of academic dishonesty will be reported to the Academic Judiciary. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at http://www.stonybrook.edu/uaa/academicjudiciary/
