Higgs EFT for 2HDM and beyond
We discuss the validity of the Standard Model Effective Field Theory (SM EFT) as the low-energy effective theory for the two-Higgs-doublet Model (2HDM). Using the up-to-date Higgs signal strength measurements at the LHC, one can obtain a likelihood function for the Wilson coefficients of dimension-6 operators in the EFT Lagrangian. Given the matching between the 2HDM and the EFT, the constraint...
متن کاملNaturalness Reach of the Large Hadron Collider in Minimal Supergravity
We re-analyse the prospects of discovering supersymmetry at the LHC, in order to re-express coverage in terms of a fine-tuning parameter and to extend the analysis to scalar masses (m0) above 2 TeV. We use minimal supergravity (mSUGRA) unification assumptions for the SUSY breaking parameters. Such high values of m0 have recently been found to have a focus point, leading to relatively low fine-t...
متن کاملDirect, Indirect and Collider Detection of Neutralino Dark Matter In SUSY Models with Non-universal Higgs Masses
In supersymmetric models with gravity-mediated SUSY breaking, universality of soft SUSY breaking sfermion masses m0 is motivated by the need to suppress unwanted flavor changing processes. The same motivation, however, does not apply to soft breaking Higgs masses, which may in general have independent masses from matter scalars at the GUT scale. We explore phenomenological implications of both ...
متن کاملIndirect Collider Tests for Large Extra
We review the capability of colliders to detect the virtual exchange of Kaluza-Klein towers of gravitons within the low scale quantum gravity scenario of Arkani-Hamed, Dimopoulos and Dvali.
متن کاملIndirect Collider Signals for Extra Dimensions
A recent suggestion that quantum gravity may become strong near the weak scale has several testable consequences. In addition to probing for the new large (submillimeter) extra dimensions associated with these theories via gravitational experiments, one could search for the Kaluza Klein towers of massive gravitons which are predicted in these models and which can interact with the fields of the...
