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.
