Chiral Baryon with Quantized Pions
Abstract
We study a hybrid chiral model for the nucleon based on the linear sigma model with explicit quarks. We solve the model using a Fockspace configuration consisting of three quarks plus three quarks and a pion as the ground state ansatz in place of the ``hedgehog'' ansatz. We minimize the expectation value of the chiral hamiltonian in this ground state configuration and solve the resulting equations for nucleon quantum numbers. We calculate the canonical set of nucleon observables and compare with previous work.
