重子形变SQCD的树级亚稳性和规范介导
Tree Level Metastability and Gauge Mediation in Baryon Deformed SQCD
摘要：
我们研究了具有SU（2）规范群的超对称QCD和一个超势的重子形变。证明了在具有树级亚稳性的起源处存在抬升的真空。当这个模型是在一个直接规范调解方案实施，因此，我们发现高根质量是可比的sfermion质量和参数化的有效信使数1/8。所有的变形都是由电理论和R对称性引起的。这种R对称性被负责超对称性破缺的同一项明确破缺。此外，该模型不受朗道极点问题，我们发现，它可以描述在只有两个尺度：弱尺度和高尺度，如普朗克或大统一体尺度。该模型可以通过寻找新的粒子在TeV尺度下的可视扇区规范组充电进行测试。
英文摘要：
We investigate supersymmetric QCD with gauge group SU(2) and a baryon deformation to the superpotential. The existence of an uplifted vacuum at the origin with tree level metastability is demonstrated. When this model is implemented in a direct gauge mediation scenario we therefore find gaugino masses which are comparable to sfermion masses and parameterised by an effective number of messengers 1/8. All deformations are well motivated by appealing to the electric theory and an R-symmetry. This R-symmetry is explicitly broken by the same term responsible for supersymmetry breaking. Moreover, the model does not suffer from the Landau pole problem and we find that it can be described in terms of just two scales: the weak scale and a high scale like the Planck or GUT scale. The model can be tested by searching for new particles at the TeV scale charged under the visible sector gauge group.
