Constraining natural SUSY via the Higgs coupling and the muon anomalous magnetic moment measurements

AbstractWe use the Higgs coupling and the muon anomalous magnetic moment measurements to constrain the parameter space of the natural supersymmetry in the generalized minimal supergravity (GmSUGRA) model. We scan the parameter space of the GmSUGRA model with small electroweak fine-tuning measure (Delta(EW) <= 100). The parameter space after applying various sparticle mass bounds; Higgs mass bounds; B-physics bounds; the muon magnetic moment constraint; and the Higgs coupling constraint from measurements at HL-LHC, ILC, and CEPC is shown in the planes of various interesting model parameters and sparticle masses. Our study indicates that the Higgs coupling and muon anomalous magnetic moment measurements can constrain the parameter space effectively. It is shown that Delta(EW) similar to 30, consistent with all constraints, and having supersymmetric contributions to the muon anomalous magnetic moment within 1 sigma can be achieved. The precision of k(b) and k(tau) measurements at CEPC can bound m(A) to be above 1.2 TeV and 1.1 TeV respectively. The combination of the Higgs coupling measurement and muon anomalous magnetic moment measurement constrain the (e) over tilde (R) mass to be in the range from 0.6 TeV to 2 TeV. The range of both (e) over tilde (L) and (v) over tilde (e) masses is 0.4 TeV-1.2 TeV. In all cases, the (X) over tilde (0)(1) mass needs to be small (mostly <= 400 GeV). The comparison of bounds in the tan beta - m(A) plane shows that the Higgs coupling measurement is complementary to the direct collider searches for heavy Higgs when constraining the natural SUSY. A few mass spectra in the typical region of parameter space after applying all constraints are shown as well.
