Constructing Class Fields of Local Fields

Let $K$ be a $p$-adic field. We give an explicit characterization of the abelian extensions of $K$ of degree $p$ by relating the coefficients of the generating polynomials of extensions $L/K$ of degree $p$ to the norm group $N_{L/K}(L^*)$. This is applied in the construction of class fields of degree $p^m$.
