Abstract
We consider a supersymmetric model with a new strong interacting sector. The model is built on a strongly interacting N=4 Super Yang Mills sector, broken explicitly to N=1 supersymmetry by embedding within the Minimal Supersymmetric Standard Model (MSSM). Due to cancellation of global and gauge anomalies, the model additionally features a fourth lepton superfamily. We propose a scenario where all elementary scalars, gauging and higgsinos are decoupled at an energy scale substantially higher than the electroweak (EW) scale, thereby avoiding the little hierarchy problem of MSSM.We construct a low energy effective model, where EW symmetry breaking and viable mass spectrum are produced dynamically. To test further the viability of the model, we work out the Higgs couplings as well as the EW precision parameters and then perform a goodness of fit analysis using LHC and EW precision data. The model fits the given experimental data at a level comparable to that of the Standard Model.
Highlights
The data collected at the LHC experiments during the 7 and 8 TeV runs, with the epochal discovery of the Higgs boson [1, 2] and the measurement of its couplings [3, 4], seem to have provided the experimental verification of the Standard Model (SM) in its entirety
We started from the ultraviolet complete model obtained by coupling Minimal Walking Technicolor and the SM with two Higgs doublets and supersymmetrizing the entire theory
We considered a situation where the supersymmetry breaking occurs at scales much higher than the electroweak scale, leading to decoupling of all elementray scalars, gauginos, and higgsinos
Summary
The data collected at the LHC experiments during the 7 and 8 TeV runs, with the epochal discovery of the Higgs boson [1, 2] and the measurement of its couplings [3, 4], seem to have provided the experimental verification of the Standard Model (SM) in its entirety. If the ETC gauge group breaks sequentially, such ETC model may explain the observed mass hierarchies of the SM fermions [19, 20] Another framework for extending TC with couplings to SM matter fields is bosonic TC (BTC). In MSCT the low energy effective theory is Minimal Walking Technicolor (MWT) [11, 30, 31] whose global symmetry is SU(4). We show that even though the particle content of the model is large, the low energy mass spectrum required by phenomenological viability can be simple: All the elementary scalars and gauginos are assumed heavy and integrated out.
