狄拉克-高吉诺超对称模型为标准模型之外的物理学提供了一个有吸引力的场景。对撞机上的“超软”辐射修正和被抑制的超对称性产生提供了更自然的理论,并解释了为什么没有看到新的状态。不幸的是,这些模型是由一个快子,这是自然存在于现有的狄拉克gauginos模型的障碍。我们认为,这种快子是不存在的,与保留的模型的现象学上的成功,如果右手的高吉诺是一个(伪)戈德斯通场的自发打破异常味对称。
Models of supersymmetry with Dirac gauginos provide an attractive scenario for physics beyond the standard model. The "supersoft" radiative corrections and suppressed supersymmetry production at colliders provide for more natural theories and an understanding of why no new states have been seen. Unfortunately, these models are handicapped by a tachyon which is naturally present in existing models of Dirac gauginos. We argue that this tachyon is absent, with the phenomenological successes of the model preserved, if the right-handed gaugino is a (pseudo-)Goldstone field of a spontaneously broken anomalous flavor symmetry.
