Some Remarks on the Matching Conditions

High Energy Physics - Phenomenology 2009-10-28 v2

Abstract

We analyze the matching conditions to determine the values that the O(p4){\cal O}(p^4) coefficients of an Effective Chiral Lagrangian take in the Standard Model in the limit of a large Higgs mass, pointing out a number of subtleties that appear to have gone unnoticed previously. We apply the resulting Effective Chiral Lagrangian, including the leading two loop effects, to analyze the most recent electroweak data assuming mtop=174±10m_{top}=174\pm 10 GeV.

14 pages + 2 figures (Postscript), TeX, UB-ECM-PF 94/12. We have found a mistake in (5.12) affecting the values of $a_{4}-a_{13}$ and $a_{5}+a_{13}$. These values have been corrected in the current version
