Field Theory and Relativistic Quantum Mechanics

Physics 721

 

Fall Semester 2011

 

Also available at   http://physics.wm.edu/~carlson/phys721.html

 

Goals:  Learn to

¥Combine quantum mechanics with special relativity,

¥Describe creation and destruction of matter and other physical states,

¥Calculate decay rates and scattering probabilities when states are created or destroyed and relativity is important.
