论文摘要
我们研究Cp-浓度中性的Higgs玻色子衰变$ h \ to c \ bar {c}，b \ bar {b}，b \ bar {s}，γγ，γγ，g g $在最小的超对称标准模型（MSSM）中，带有一般夸张的风味蛋白（qfv），识别h等于higs gs a higs higs higs boson boson。我们将H衰变的宽度计算为$ c \ bar c，b \ bar b，b \ bar s（s \ bar b）$在完整的一环级别上。对于循环诱导的H衰变至光子光子和Gluon Gluon，我们计算NLO QCD水平的宽度。 {\ it第一次}，我们执行系统的MSSM参数扫描，包括超对称（SUSY）QFV参数，尊重所有相关约束，即来自真空稳定性条件和实验性约束的理论约束，例如来自K-和B-Meson Data，Electoweak Precimision Data和125 GIM的实验，以及bos的实验，以及125 GIM的bos bos bos bos bos bos bos bos bos bos bos。随着LHC实验的SUSY粒子质量的限制。我们还考虑了未来HL-LHC实验中预期的SUSY粒子质量限制。 {\与}与夸克风味的MSSM中的常规研究相反，我们发现这些MSSM衰减宽度与标准模型（SM）值的偏差可能相当大，并且这些偏差之间存在显着的相关性。 ILC，CLIC，CEPC，FCC-EE和MUC等未来的Lepton Colliders可以观察到与SM在HL-LHC处发现SUSY粒子发现的失败的高信号意义的SM偏差。如果此处显示的偏差模式确实是在Lepton Collider上观察到的，那么它将强烈建议发现QFV SUSY（具有一般QFV的MSSM）。
We study the CP-even neutral Higgs boson decays $h \to c \bar{c}, b \bar{b}, b \bar{s}, γγ, g g$ in the Minimal Supersymmetric Standard Model (MSSM) with general quark flavor violation (QFV), identifying the h as the Higgs boson with a mass of 125 GeV. We compute the widths of the h decays to $c \bar c, b \bar b, b \bar s (s \bar b)$ at full one-loop level. For the loop-induced h decays to photon photon and gluon gluon we compute the widths at NLO QCD level. {\it For the first time}, we perform a systematic MSSM parameter scan including Supersymmetric (SUSY) QFV parameters respecting all the relevant constraints, i.e. theoretical constraints from vacuum stability conditions and experimental constraints, such as those from K- and B-meson data, electroweak precision data, and the 125 GeV Higgs boson data from recent LHC experiments, as well as the limits on SUSY particle masses from the LHC experiment. We also take into account the expected SUSY particle mass limits from the future HL-LHC experiment in our analysis. {\it In strong contrast to} the usual studies in the MSSM with quark flavor conservation, we find that the deviations of these MSSM decay widths from the Standard Model (SM) values can be quite sizable and that there are significant correlations among these deviations. Future lepton colliders such as ILC, CLIC, CEPC, FCC-ee and MuC can observe such sizable deviations from the SM at high signal significance {\it even after} the failure of SUSY particle discovery at the HL-LHC. In case the deviation pattern shown here is really observed at the lepton colliders, then it would strongly suggest the discovery of QFV SUSY (the MSSM with general QFV).
