具有非泛Gaugino质量的自然性和焦点

Naturalness and Focus Points with Non-Universal Gaugino Masses

D. Horton, G. G. Ross

摘要:

已经证明,高吉诺质量之间的关系,以减轻在MSSM微调的程度。在本文中,我们考虑特定的模型与重力调解的超对称性破缺,并证明,在大统一理论和字符串结构,它是可能的,以自然的方式产生这些关系。我们已经数值研究了这些模型中的微调程度,包括单循环校正,并找到了参数空间区域,可以满足所有已知的对撞机的约束与微调小于20%。我们讨论了一些现象学的功能,这些模型内的区域减少微调。

英文摘要:

Relations between the gaugino masses have been shown to alleviate the degree of fine-tuning in the MSSM. In this paper we consider specific models of supersymmetry breaking with gravity mediation and demonstrate that within both GUT and string constructions it is possible to generate these relations in a natural way. We have numerically studied the degree of fine-tuning in these models, including one-loop corrections, and have found regions of parameter space that can satisfy all known collider constraints with fine-tunings less than 20%. We discuss some of the phenomenological features of these models within the regions of reduced fine-tuning.
