Tree Level Gauge Mediation

Marco Nardecchia, Andrea Romanino, Robert Ziegler

摘要:

我们提出了一个新的方案,其中超对称性破缺的沟通MSSM sfermions的GUT规范相互作用在树的水平。MSSM场对$\text{Str}(\mathcal{M}^2)$的(正)贡献由重场的(负)贡献自动补偿。斯费米子质量是味普适的,从而解决了超对称味问题。在最简单的SO(10)嵌入中,不同sfermion质量的比率被预测,并且与mSugra和其他方案不同,因此使这个框架在LHC上可测试。高吉诺群众产生的循环水平,但增强模型相关因素。

英文摘要:

We propose a new scheme in which supersymmetry breaking is communicated to the MSSM sfermions by GUT gauge interactions at the tree level. The (positive) contribution of MSSM fields to $\text{Str}(\mathcal{M}^2)$ is automatically compensated by a (negative) contribution from heavy fields. Sfermion masses are flavour universal, thus solving the supersymmetric flavour problem. In the simplest SO(10) embedding, the ratio of different sfermion masses is predicted and differs from mSugra and other schemes, thus making this framework testable at the LHC. Gaugino masses are generated at the loop level but enhanced by model dependent factors.
