Abstract
We study the Abelian Higgs model using an improved form of the action in the scalar sector. The subleading corrections are carefully analyzed and the connection between lattice and continuous parameters is worked out. The model is simulated for mH = 30GeV and a remarkable improvement of the numerical performance is achieved for this value of the Higgs mass.
