Canonical quantization of spin-3/2 particle

  1. Apr 11, 2015 #1
    If I want to calculate a decay of excited nucleons,sometimes I must treat the spin 3/2 field operator.
    If I use CG coefficient method, for example
    http://arxiv.org/abs/hep-ph/0210164 (page 3,the third equation)

    But it is a result,not the starting.The thought looks like a synthesis between a vector particle and a spinor one.But how about the expension of original field operator in momentum space into annihilation and creation operators?We will see a direct product of two ladder operator?But the CG coefficient must has its status,so the summation rule of polarization vector and Dirac spinor must be very complicated,is there any established work?
