味破坏和等级化的费米子

Flavor Violation and Hierarchical Sfermions

Marco Nardecchia

摘要:

自然性论证并不排除前两族的方子和slepton比超对称谱的其余部分重的可能性。在这个框架下,我们研究了与味物理相关的现象学,给出了味违反参数的界,并与近简并方的情况进行了比较。层次结构的特殊结构,使我们能够作出明确的预测,并建议也自然大小的味道违反参数。

英文摘要:

Naturalness arguments do not forbid the possibility that the first two families of squarks and sleptons are heavier than the rest of the supersymmetric spectrum. In this framework, we study the phenomenology related to the flavor physics and we give bounds on the flavor violating parameters that we compare with the case of nearly degenerate squarks. The peculiar structure of the hierarchical scheme allows us to make definite predictions and suggests also a natural size for the flavor violating parameters.
