As discussed in the previous lecture, scattering experiments have been a fruitful and ecient
way to determine the particles which exist in nature and how they interact. In a

So far, we have studied quantum eld theory using the canonical quantization approach, which
is based on creation and annihilation operators. There is a completely dierent way to do

Why dont students see this and study
more physics?
Perhaps it is because when students read course catalogs, they often
get no hint of the great ferment going
on in our laboratories. Many physics

II-5: Spin and Statistics
1 Introduction
One of the most profound consequences of merging special relativity with quantum mechanics is
the spin-statistics theorem: states with identical particles of integer spin are symmetric under

Quantum mechanics began on October 19, 1900 with Max Plancks explanation of the blackbody radiation spectrum. Actually, although Plancks result helped lead to the development

Last time we saw that if we treat each mode of the photon as a separate particle, and give it
multiple excitations like a harmonic oscillator, we can derive Einsteins rel

Now we are ready to do calculations in QED. We have found that the Lagrangian for QED is

II-2: Scalar QED

Now that we have Feynman rules and we know how to quantize the photon, we are very close to
quantum electrodynamics. All we need is the electron, which is a spinor. Before we get into
spinors, however,

time-ordered products of elds. The S-matrix has the form
