Abstract

In this paper, we consider the β\beta function at one-loop approximation for noncommutative scalar QED. The renormalization of the full theory, including the basic vertices, and the renormalization group equation are fully established. Next, the complete set of the one-loop diagrams corresponding to the first-order radiative corrections to the basic functions is considered: gauge, charged scalar and ghost fields self-energies, and three- and four-point vertex functions <ϕϕA>\left<\phi^\dag \phi A\right> and <ϕϕAA>\left<\phi^\dag \phi A A\right>, respectively. We pay special attention to the noncommutative contributions to the renormalization constants. To conclude, the one-loop β\beta function of noncommutative scalar QED is then computed and comparison to known results is presented.
