摘要: We study Higgs production and decays in the context of natural SUSY, allowing for an extended sector to account a 125 GeV lightest boson. Under broad assumptions, observables at LHC depend on most four free parameters with restricted numerical ranges. Two suffice describe MSSM particle loops. The loop contribution diphoton rate is constrained from above by direct stop chargino searches electroweak precision tests. Naturalness, particular demanding that rare B remain consistent experiment without fine-tuned cancellations, provides lower (upper) bound Higgs-gluon coupling (Higgs mass). mixing, even presence induced non-holomorphic Yukawa couplings. Generic classes extensions, address fine-tuning problem, predict sizable modifications effective bottom y b . Non-decoupling gauge extensions enhance , while heavy SM singlet reduces A factor 4–6 enhancement LHC, compared prediction, can be accommodated. ratio enhancements vs. WW ZZ channels cannot exceed 1.4. h → $ b\overline{b} $ associated more than 50%.
