标题： Vector-like Strong Coupling Theory with Small S and T Parameters

摘要： 我们讨论一种机制，可以在动态电弱对称性破缺情景中减少S和T参数。 有趣的是，即使存在大的同位旋破坏，不仅T参数而且S参数也可以变得很小，这可以实现重的顶夸克。 关键是如果具有规范不变质量的大量矢量样费米子能够凝聚并打破电弱对称性，由于解耦定理，S和T参数可以变得很小。 此外，该模型预测了一个更重的希格斯玻色子，这可能在大型强子对撞机中被发现。 该演示基本上遵循原始论文。 显示英文摘要

摘要： We discuss a mechanism which can reduce the S and T parameters in dynamical electroweak symmetry breaking scenario. It is interesting that not only T but also S parameters can be made small even if large isospin violation exists, which can realize the heavy top quark. The point is that if massive vector-like fermions, which have gauge invariant masses, can condense and break the electroweak symmetry, the S and T parameters can be small because of the decoupling theorem. Moreover, the model predicts a heavier Higgs boson, which may be found in LHC. The presentation basically follows the original papers.
