复合希格斯粒子的味扇区

A Flavor Sector for the Composite Higgs

Luca Vecchi

摘要:

讨论了大N复合Higgs模型中的味破坏。我们专注于方案中的质量的标准模型费米子控制的分层混合参数,在模型的部分复合。我们认为,风味和希格斯动力学之间的尺度分离可以采用参数抑制偶极和企鹅运营商,从而有效地消除轻子部门和中子EDM所产生的实验约束。因此,超过标准模型的风味违反的主要来源是由4-费米子运营商,其威尔逊系数可以与提供的希格斯动力学方法的“行走”制度的IR数据兼容。模型符合所有的风味和电弱数据可以得到一个新的物理尺度在LHC的范围内。明确的情况下,可以实现在一个5D的框架,新的关键成分是味道膜的散装费米子结束的波函数的介绍。

英文摘要:

We discuss flavor violation in large N Composite Higgs models. We focus on scenarios in which the masses of the standard model fermions are controlled by hierarchical mixing parameters, as in models of Partial Compositeness. We argue that a separation of scales between flavor and Higgs dynamics can be employed to parametrically suppress dipole and penguin operators, and thus effectively remove the experimental constraints arising from the lepton sector and the neutron EDM. The dominant source of flavor violation beyond the standard model is therefore controlled by 4-fermion operators, whose Wilson coefficients can be made compatible with data provided the Higgs dynamics approaches a "walking" regime in the IR. Models consistent with all flavor and electroweak data can be obtained with a new physics scale within the reach of the LHC. Explicit scenarios may be realized in a 5D framework, the new key ingredient being the introduction of flavor branes where the wave functions of the bulk fermions end.
