Homework Statement
Problem 3.4e of Peskin & Schroeder Introduction to Quantum Field Theory. Quantize the spinor theory of item (a) of this exercise, where the spinor [tex]\chi[/tex] is the first two components of the Dirac spinor ([tex]\psi_L[/tex]). Find a Hermitean Hamiltonian and the correct creation/annihilation operators that diagonalize it.
Homework Equations
The Majorana mass equation for these components [tex]\[i\bar{\sigma}\cdot\partial\chi=im\sigma^2\chi^*\][/tex]
(item a), the anticommutation relations for the components of the spinor
[tex]\[\{\chi_a(x),\chi^\dagger_b(y) \}=\delta_{ab}\delta(\vec{x}-\vec{y})\][/tex].
The Attempt at a Solution
Many. The problem is that I cannot find the correct expansions of the fields and the correct normalizations to diagonalize the Hamiltonian. The fact that the equations mix [tex]\chi[/tex] with [tex]\chi^\dagger[/tex] doesn't allow to use the usual methods and I could not find this done in any book. Pointing to a book or a partial/full solution in the internet would already be a great help. General suggestions and tips are also very, very welcome.
