Título: | A constrained supersymmetric left-right model |
Autor: | Hirsch, Martin CSIC ORCID; Krauss, Manuel E.; Opferkuch, Toby; Porod, Werner CSIC; Staub, Florian | Palabras clave: | Supersymmetry Phenomenology | Fecha de publicación: | 2-mar-2016 | Editor: | Springer Nature | Citación: | Journal of High Energy Physics 03 (3): 009 - 22 (2016) | Resumen: | We present a supersymmetric left-right model which predicts gauge coupling unification close to the string scale and extra vector bosons at the TeV scale. The subtleties in constructing a model which is in agreement with the measured quark masses and mixing for such a low left-right breaking scale are discussed. It is shown that in the constrained version of this model radiative breaking of the gauge symmetries is possible and a SM-like Higgs is obtained. Additional CP-even scalars of a similar mass or even much lighter are possible. The expected mass hierarchies for the supersymmetric states differ clearly from those of the constrained MSSM. In particular, the lightest down-type squark, which is a mixture of the sbottom and extra vector-like states, is always lighter than the stop. We also comment on the model's capability to explain current anomalies observed at the LHC. | Descripción: | 21 pages.- 5 figures.- v2: references added, matches published version | Versión del editor: | http://dx.doi.org/10.1007/JHEP03(2016)009 | URI: | http://hdl.handle.net/10261/130749 | DOI: | 10.1007/JHEP03(2016)009 | ISSN: | 1029-8479 |
