I have taken heat from a QFT professor for not including the 2nd type of Bhabha scattering in here and for some loose edges. This was all intentional to simplify things at the outset and is fully set straight in Chap. 8. However, to hopefully avoid such criticism in the future, I have amended these pages of Chap. 1 (See link to Chap. 1 on home page.)

Jan 14, 2014

Better pedagogically if in the paragraph after (12-15), change the 1st part of the 1st sentence up to “… when” to

The paragraph after heading “Average Ove Initial Spins” may be easier to understand if re-written as

 Scattering experiments typically do not measure the spins of particles. So what we do is consider the beam of incoming particles to be in an “average” spin state. What we mean by average spin state is that half of the incoming particles are taken to be in the s=1 spin state and half in the s=2 spin state. This will reflect our lack of knowledge of the individual spin state of each incoming particle.
