摘要：

Using the Zaragoza proposal for lattice chiral gauge fermions, the S, U and DELTArho parameters have been calculated at one loop. It is shown that the continuum values for these quantities can be reproduced without requiring explicit fine tuning of counterterms. Furthermore, fermion fields doubling is not necessary. To the best of our knowledge, the Zaragoza proposal is the only scheme which has these properties.
