Constraints on the NMSSM from the Oblique Parameters

Figure 2

(a): Oblique parameters 𝑆 and 𝑇 in the NMSSM in the constrained case with central parameters tan(𝛽)=1.7, 𝑀₀=𝑀_1/2=500 GeV, 𝐴₀=−800 GeV, 𝐴_𝜅=−1500 GeV, sgn(𝜇)=+, and 𝜆=0.5 (second row in Table 1) with successive variations of the parameters 𝑀₀=250 GeV, 300 GeV,…,500 GeV, 𝑀_1/2=450 GeV, 500 GeV,…,650 GeV, 𝐴₀=−800 GeV,  −700 GeV,…,−100 GeV, as indicated in the figure. (b): Same as (a) but with central parameters tan(𝛽)=5, 𝑀₀=100 GeV, 𝑀_1/2=200 GeV, 𝐴₀=−700 GeV, 𝐴_𝜅=−75 GeV, sgn(𝜇)=+, and 𝜆=0.2 with successive variations of the parameters tan(𝛽)=2,3,…,15, 𝑀₀=0 GeV,  100 GeV,…,800 GeV, 𝑀_1/2=200 GeV,  225 GeV,…,400 GeV.
