Título: | Colorful imprints of heavy states in the electroweak effective theory |
Autor: | Krause, Claudius; Pich, Antonio CSIC ORCID; Rosell, Ignasi CSIC ORCID; Santos, Joaquín; Sanz-Cillero, Juan José CSIC ORCID | Fecha de publicación: | may-2019 | Editor: | Institute of Physics Publishing | Citación: | Journal of High Energy Physics 2019: 92 (2019) | Resumen: | We analyze heavy states from generic ultraviolet completions of the Standard Model in a model-independent way and investigate their implications on the low-energy couplings of the electroweak effective theory. We build a general effective Lagrangian, implementing the electroweak symmetry breaking SU(2) ⊗ SU(2) → SU(2) with a non-linear Nambu-Goldstone realization, which couples the known particles to the heavy states. We generalize the formalism developed in previous works [1, 2] to include colored resonances, both of bosonic and fermionic type. We study bosonic heavy states with J = 0 and J = 1, in singlet or triplet SU(2) representations and in singlet or octet representations of SU(3) , and fermionic resonances with J=12 that are electroweak doublets and QCD triplets or singlets. Integrating out the heavy scales, we determine the complete pattern of low-energy couplings at the lowest non-trivial order. Some specific types of (strongly- and weakly-coupled) ultraviolet completions are discussed to illustrate the generality of our approach and to make contact with current experimental searches. | URI: | http://hdl.handle.net/10261/194581 | DOI: | 10.1007/JHEP05(2019)092 | Identificadores: | doi: 10.1007/JHEP05(2019)092 issn: 1029-8479 |
