We build a general effective Lagrangian, implementing the electroweak chiral symmetry breaking SU(2)(L) circle times SU(2)(R) -> SU(2)(L+R), which couples the known particle fields to heavier states with bosonic quantum numbers J(P) = 0(+/-) and 1(+/-). We consider colour-singlet heavy fields that are in singlet or triplet representations of the electroweak group. Integrating out these heavy scales, we analyze the pattern of low-energy couplings among the light fields which are generated by the massive states. We adopt a generic non-linear realization of the electroweak symmetry breaking with a singlet Higgs, without making any assumption about its possible doublet structure. Special attention is given to the different possible descriptions of massive spin-1 fields and the differences arising from naive implementations of these formalisms, showing their full equivalence once a proper short-distance behaviour is required.", optnote="WOS:000398449400004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3074), last updated on Thu, 11 May 2017 16:24:07 +0000", issn="1029-8479", doi="10.1007/JHEP04(2017)012", opturl="http://arxiv.org/abs/1609.06659", opturl="https://doi.org/10.1007/JHEP04(2017)012", archivePrefix="arXiv", eprint="1609.06659", language="English" }
