Effective description of general extensions of the Standard Model: the complete tree-level dictionary Blas Mateo, Jorge de Criado Álamo, Juan Carlos Pérez-Victoria, Manuel Santiago Pérez, José Beyond Standard Model Effective Field Theories We thank Nuria Rius and Arcadi Santamaria for an interesting discussion that motivated this work. We also thank Paco del Águila and Toni Pich for useful comments. We compute all the tree-level contributions to the Wilson coefficients of the dimension-six Standard-Model effective theory in ultraviolet completions with general scalar, spinor and vector feld content and arbitrary interactions. No assumption about the renormalizability of the high-energy theory is made. This provides a complete ultraviolet/ infrared dictionary at the classical level, which can be used to study the low-energy implications of any model of interest, and also to look for explicit completions consistent with low-energy data 2018-05-30T08:37:28Z 2018-05-30T08:37:28Z 2018-03-19 info:eu-repo/semantics/article Blas Mateo, Jorge de; et. al.
