甜蜜点超对称与复合信息
Sweet Spot Supersymmetry and Composite Messengers
摘要：
甜蜜点超对称是实现近距离超对称世界的唯象和宇宙学的完美框架。我们讨论了一类超对称破缺及其中介的动力学模型，其低能有效描述属于这个框架。动力学模型中的强子场扮演着超对称破缺信使的角色。在甜蜜点超对称模型中，信使尺度被预测为10^5 GeV < M_mess < 10^{10} GeV。信使字段的有效数量N_mess的各种值是可能的，这取决于规范组的选择。
英文摘要：
Sweet spot supersymmetry is a phenomenologically and cosmologically perfect framework to realize a supersymmetric world at short distance. We discuss a class of dynamical models of supersymmetry breaking and its mediation whose low-energy effective description falls into this framework. Hadron fields in the dynamical models play a role of the messengers of the supersymmetry breaking. As is always true in the models of the sweet spot supersymmetry, the messenger scale is predicted to be 10^5 GeV < M_mess < 10^{10} GeV. Various values of the effective number of messenger fields N_mess are possible depending on the choice of the gauge group.
