Abstract: Szegő polynomials with respect to the weight function $ \omega(\theta) = e^{\eta \theta} [\sin(\theta/2)]^{2\lambda}$, where $ \eta, \lambda \in \mathbb{R}$ and $ \lambda > -1/2$ are considered. Many of the basic relations associated with these polynomials are given explicitly. Two sequences of para-orthogonal polynomials with explicit relations are also given.
