The fermion mass hierarchy does not have an explanation in the Standard Model (SM). Moreover, an inverted hierarchy of the sfermion masses is suggested by the constraints from LHC data. To explain these known and expected hierarchies, we consider a supersymmetric model that uses partial-compositeness. The Higgs and third-generation matter superfields are elementary while the first two matter...
Supersymmetric models are subject both to direct constraints from collider searches and to indirect limits from electroweak observables such as the Higgs mass and flavor-changing processes. A minimal scenario consistent with current experimental data suggests a supersymmetric spectrum with a split sfermion sector. Such a spectrum can naturally be realized when supersymmetry is broken in a...
We present best-fit constraints on three different dark energy models. We analyzed 31 measurements of the Hubble expansion rate, as well as 11 distance measurements scaled to the sound horizon set by baryon acoustic oscillations. Our analysis finds that the data favor a slightly closed Lambda-CDM model (as opposed to the conventional flat Lambda-CDM model), although not above the 1-sigma level.
