Dobado González, Antonio ; Herrero, M.J. ; Peñaranda, Siannah | World Scientific Publ Co Pte Ltd | 1998A heavy supersymmetric spectrum at the Minimal Supersymmetric Standard Model is considered and the decoupling from the low energy electroweak scale is analyzed. A formal and partial proof of decoupling of supersymmetric particles in the limit wh[...]texto impreso
In SU(5)/SO(5) little Higgs models radiative corrections give rise to SU(2)(L)xU(1)(Y) symmetry breaking. In this work we start a program for a detailed determination of the relevant terms of the effective Higgs potential by computing the contri[...]texto impreso
Dobado González, Antonio ; Tabares Cheluci, Lourdes ; Peñaranda, Siannah ; Rodríguez Laguna, Javier | Springer | 2010-04In this work we compute the radiative corrections to the Higgs mass and the Higgs quartic couplings coming from the Higgs sector itself and the scalar fields phi in the Littlest Higgs (LH) model. The restrictions that the new contributions set o[...]texto impreso
We study the heavy Higgs sector of the MSSM composed of the H+/-, H-0 and A(0) particles in the so-called decoupling limit where m(A0) > > m(z) By integrating out these heavy Higgs particles to one-loop, we compute the effective action for the [...]texto impreso
In the framework of the minimal supersymmetric standard model we compute the one-loop effective action for the electroweak bosons obtained after integrating out the different sleptons, squarks, neutralinos and charginos, and present the result i[...]texto impreso
We compute the relevant parameters of the combined Higgs and phi scalar effective potential in the littlest Higgs (LH) model. These parameters are obtained as the sum of two kinds of contributions. The first one is the one-loop radiative correct[...]
