层次软术语与风味物理

Hierarchical Soft Terms and Flavor Physics

Gian F. Giudice, Marco Nardecchia, Andrea Romanino

摘要:

我们研究了层次软条款的框架,其中前两代的squarks和slepton比其余的超对称谱更重。该计划提供了独特的预测的味道违反的模式,我们比较的情况下,几乎退化的平方。风味物理学的实验已经开始探索最有趣的参数区域,特别是在$b\leftrightarrow s$转变中,其中分层软项可以预测比标准模型大得多的$B_s$混合相。

英文摘要:

We study the framework of hierarchical soft terms, in which the first two generations of squarks and sleptons are heavier than the rest of the supersymmetric spectrum. This scheme gives distinctive predictions for the pattern of flavor violations, which we compare to the case of nearly degenerate squarks. Experiments in flavor physics have started to probe the most interesting parameter region, especially in $b\leftrightarrow s$ transitions, where hierarchical soft terms can predict a phase of $B_s$ mixing much larger than in the Standard Model.
