在LHC上的异常调解测试

Test of Anomaly Mediation at the LHC

Shoji Asai, Takeo Moroi, T. T. Yanagida

摘要:

在反常介导的超对称破缺模型中,假设Kahler势的一般形式,高吉诺是LHC唯一运动学上可接近的超粒子。我们认为这样一个模型的LHC现象,假设胶子是轻于1 TeV。我们表明,一个显着数量的收费Winos,这可能会旅行O(10厘米)之前的衰变,产生的胶子生产过程。因此,在这类模型中,利用内探测器寻找短的带电径迹将是非常重要的。我们还表明,如果大量的带电威诺轨道被确定,带电威诺的寿命可以测量,这为我们提供了一个测试异常调解。

英文摘要:

In the anomaly-mediated supersymmetry breaking model with the assumption of the generic form of Kahler potential, gauginos are the only kinematically accessible superparticles to the LHC. We consider the LHC phenomenology of such a model assuming that the gluino is lighter than 1 TeV. We show that a significant number of charged Winos, which may travel O(10 cm) before the decay, are produced from the gluino production processes. Thus, in this class of model, it will be very important to search for short charged tracks using inner detectors. We also show that, if a large number of the charged Wino tracks are identified, the lifetime of the charged Wino can be measured, which provides us a test of anomaly mediation.
