QCD中的广义Skyrmions和电弱扇区

Generalized Skyrmions in QCD and the Electroweak Sector

John Ellis, Marek Karliner, Michal Praszalowicz

摘要:

本文讨论了QCD中拓扑孤子的稳定性和质量,以及场空间导数中两个不等价的四阶Lagrange项任意组合的电弱对称破缺强相互作用模型。我们发现稳定的孤子只有一个有限的范围内的比例,这些组合,与以前的结果一致,我们计算相应的孤子质量。在QCD中,四阶项的实验约束迫使孤子类似于原始的Skyrmion解。然而,在弱对称性破缺的强相互作用模型中,情况并不一定如此,在这种模型中,非Skyrmion类孤子也是可能的。这种可能性将受到未来大型强子对撞机测量和暗物质实验的限制。电流上限的电弱孤子的质量范围在18和59 TeV之间,这将减少到4.6至8.1 TeV的LHC数据的四阶电弱拉格朗日参数的可能的敏感性。

英文摘要:

We discuss the stability and masses of topological solitons in QCD and strongly-interacting models of electroweak symmetry breaking with arbitrary combinations of two inequivalent Lagrangian terms of fourth order in the field spatial derivatives. We find stable solitons for only a restricted range of the ratio of these combinations, in agreement with previous results, and we calculate the corresponding soliton masses. In QCD, the experimental constraints on the fourth-order terms force the soliton to resemble the original Skyrmion solution. However, this is not necessarily the case in strongly-interacting models of electroweak symmetry breaking, in which a non-Skyrmion-like soliton is also possible. This possibility will be constrained by future LHC measurements and dark matter experiments. Current upper bounds on the electroweak soliton mass range between 18 and 59 TeV, which would be reduced to 4.6 to 8.1 TeV with the likely sensitivity of LHC data to the fourth-order electroweak Lagrangian parameters.
