THE ABELIAN HIGGS MODEL IN THREE DIMENSIONS WITH IMPROVED LATTICE ACTION

A study of the Abelian Higgs model using an improved form of the action in the scalar sector. The subleading corrections are carefully analysed and the connection between lattice and continuous parameters is worked out for M_H=30 GeV. The simulation shows a remarkable improvement of the numerical performance.
