作为邻近效应的电弱对称性破缺

Electroweak symmetry breaking as a proximity effect

S. Khlebnikov

摘要:

凝聚态物理中的邻近效应是自然产生弱超导电性的机制。我们认为,braneworld可以类似地产生一个低能量破缺的电弱对称性,只要除了“正常”的区域,由QCD的常规阶段占据,有一个散装区域的颜色是在一个各向异性(分层)状态具有较大的限制规模。W玻色子和Z玻色子,以及夸克,通过散射离开层状区域而获得质量。这种情况下的一个独特的特点是,负责对称性破缺的强相互作用部门可以比传统的1 TeV轻得多。

英文摘要:

The proximity effect in condensed matter physics is a mechanism that naturally produces weak superconductivity. We argue that a braneworld can similarly produce a low-energy breaking of the electroweak symmetry, provided that in addition to the "normal" region, occupied by the conventional phase of QCD, there is a bulk region where the color is in an anisotropic (layered) state with a larger confinement scale. The W and Z bosons, as well as the quarks, acquire masses by scattering off the layered region. A peculiar feature of this scenario is that the strongly interacting sector responsible for the symmetry breaking can be much lighter than the conventional 1 TeV.
