“…Since tan β ∼ 50, LHC searches for A, H → τ + τ − will access a significant range of m A in this case. It is also possible for some range of m A 1 TeV for LHC to access bA → bµ + µ − production [48].…”

Previous work on t − b − τ Yukawa-unified supersymmetry, as expected from SUSY GUT theories based on the gauge group SO(10), tended to have exceedingly large electroweak fine-tuning (EWFT). Here, we examine supersymmetric models where we simultaneously require low EWFT ("natural SUSY") and a high degree of Yukawa coupling unification, along with a light Higgs scalar with m h ∼ 125 GeV. As Yukawa unification requires large tan β ∼ 50, while EWFT requires rather light third generation squarks and low µ ≈ 100 − 250 GeV, B-physics constraints from BR(B → X s γ) and BR(B s → µ + µ − ) can be severe. We are able to find models with EWFT ∆ 50 − 100 (better than 1-2% EWFT) and with Yukawa unification as low as R yuk ∼ 1.3 (30% unification) if B-physics constraints are imposed. This may be improved to R yuk ∼ 1.2 if additional small flavor violating terms conspire to improve accord with B-constraints. We present several Yukawa-unified natural SUSY (YUNS) benchmark points. LHC searches will be able to access gluinos in the lower 1 − 2 TeV portion of their predicted mass range although much of YUNS parameter space may lie beyond LHC14 reach. If heavy Higgs bosons can be accessed at a high rate, then the rare H, A → µ + µ − decay might allow a determination of tan β ∼ 50 as predicted by YUNS models. Finally, the predicted light higgsinos should be accessible to a linear e + e − collider with √ s ∼ 0.5 TeV.

“…pp → bA, bH production. It may also be possible to detect bA, bH production with A, H → µ + µ − [48], since the production and decay are enhanced at large tan β. In this case, the A, H mass and width may be determined by reconstructing m(µ + µ − ).…”

Recently, it has been argued that various measures of SUSY naturalness-electroweak, Higgs mass and EENZ/BG-when applied consistently, concur with one another and make very specific predictions for natural supersymmetric spectra. Highly natural spectra are characterized by light higgsinos with mass not too far from m h and well-mixed but TeV-scale third generation squarks. We apply the unified naturalness measure to the case of heavy Higgs bosons A, H and H ± . We find that their masses are bounded from above by naturalness depending on tan β: e.g. for 10% fine-tuning and tan β ∼ 10, we expect m A < ∼ 2.5 TeV whilst for 3% fine-tuning and tan β as high as 50, then m A < ∼ 8 TeV. Furthermore, the presence of light higgsinos seriously alters the heavy Higgs boson branching ratios, thus diminishing prospects for usual searches into Standard Model (SM) final states, while new discovery possibilities arise due to the supersymmetric decay modes. The heavy SUSY decay modes tend to be H, A, H ± → W, Z, or h+ E T + soft tracks so that single heavy Higgs production is characterized by the presence of high p T W , Z or h bosons plus missing E T . These new heavy Higgs boson signatures seem to be challenging to extract from SM backgrounds. *
