强模镇定与唯象

Strong moduli stabilization and phenomenology

Emilian Dudas, Andrei Linde, Yann Mambrini, Azar Mustafayev, Keith A. Olive

摘要:

我们描述了强模稳定的弦论/超引力模型的现象学。具有F项抬升的KL模型就是这样一个例子。这种类型的模型预测普适标量质量等于引力子质量。相比之下,A-术语接收高度抑制的重力介导的贡献。在一定条件下,同样的结论对高吉诺质量也是有效的,高吉诺质量就像A项一样,由反常决定。在这样的模型中,我们被迫相对较大的引力子质量(30-1000 TeV)。我们计算低能谱作为m_{3/2}的函数。我们看到希格斯粒子的质量自然地取125-130 GeV之间的值。下限是从要求的电荷质量大于104 GeV,而上限是由遗迹密度的暗物质(酒状)。

英文摘要:

We describe the resulting phenomenology of string theory/supergravity models with strong moduli stabilization. The KL model with F-term uplifting, is one such example. Models of this type predict universal scalar masses equal to the gravitino mass. In contrast, A-terms receive highly suppressed gravity mediated contributions. Under certain conditions, the same conclusion is valid for gaugino masses, which like A-terms, are then determined by anomalies. In such models, we are forced to relatively large gravitino masses (30-1000 TeV). We compute the low energy spectrum as a function of m_{3/2}. We see that the Higgs masses naturally takes values between 125-130 GeV. The lower limit is obtained from the requirement of chargino masses greater than 104 GeV, while the upper limit is determined by the relic density of dark matter (wino-like).
