Both electroweak precision measurements and simple supersymmetric extensions of the standard model prefer a mass of the Higgs boson less than the experimental lower limit (on a standard-model-like Higgs boson) of 114 GeV. We show that supersymmetric models with R parity violation and baryon-number violation have a significant range of parameter space in which the Higgs boson dominantly decays to six jets. These decays are much more weakly constrained by current CERN LEP analyses and would allow for a Higgs boson mass near that of the Z. In general, lighter scalar quark and other superpartner masses are allowed. The Higgs boson would potentially be discovered at hadron colliders via the appearance of new displaced vertices.
电弱精确测量和标准模型的简单超对称扩展都倾向于希格斯玻色子的质量小于114 GeV(类标准模型希格斯玻色子的)实验下限。我们表明,具有R宇称破坏和重子数破坏的超对称模型有一个很大的参数空间范围,其中希格斯玻色子主要衰变为六个喷注。这些衰变受到当前欧洲核子研究中心大型正负电子对撞机(LEP)分析的限制要弱得多,并且将允许希格斯玻色子的质量接近Z玻色子的质量。一般来说,较轻的标量夸克和其他超对称伙伴的质量是允许的。希格斯玻色子可能会在强子对撞机上通过新的位移顶点的出现而被发现。
