强电弱对称性破缺(或者,如果没有SM希格斯粒子,那又怎样?)

Strong electroweak symmetry breaking (or, if no SM Higgs, then what?)

Anna Kaminska

摘要:

虽然大型强子对撞机承担了实验探索电弱对称破缺扇区的挑战,但探索具有基本标量希格斯玻色子玻色子的标准模型方案的替代方案不仅有趣,而且至关重要。讨论了由某些新的强动力学引起的电弱对称性破缺。介绍了一种简单、通用、自洽的无Higgsless模型的低能有效描述。这个有效的理论研究的角度来看,延长微扰么正性的WW散射的自旋-1共振起源于强相互作用的部门。LHC现象和发现这些自旋-1共振的潜力也进行了讨论。自旋-1共振的作用,然后被认为是复合希格斯模型的理由。明确列入这些模型的有效拉格朗日描述的共振的一般处方。

英文摘要:

While the LHC takes on the challenge of experimentally exploring the electroweak symmetry breaking sector, it is not only interesting but also crucial to explore alternatives to the Standard Model scenario with an elementary scalar Higgs boson. The idea of electroweak symmetry breaking by some new strong dynamics is discussed. A simple, general and self-consistent low energy effective description of Higgsless models is introduced. This effective theory is studied from the point of view of prolonging perturbative unitarity of WW scattering by spin-1 resonances originating from the strongly interacting sector. The LHC phenomenology and the discovery potential for these spin-1 resonances is also discussed. The role of spin-1 resonances is then considered on the grounds of composite Higgs models. A general prescription for the explicit inclusion of such resonances in the effective Lagrangian description of these models is presented.
