新矢量玻色子衰变到Higgs的共形势垒

Conformal Barrier for New Vector Bosons Decay to the Higgs

Hidenori S. Fukano, Shinya Matsuzaki, Koichi Yamawaki

摘要:

ATLAS合作最近报告了在diboson通道中质量约为2 TeV的2.5 sigma的过量,这可以用新的矢量玻色子来识别,作为新物理学的提示。它示出,自发破共形/规模对称性禁止新的矢量玻色子衰变到希格斯玻色子,这是对比流行的“等效定理”有效,只在一个特殊的限制不一定相关的2 TeV的质量。如果衰变$V\to WH/ZH$在LHC正在进行的运行II中没有被观察到,那么125 GeV的希格斯粒子可能是一个玻色子。

英文摘要:

The ATLAS collaboration has recently reported excesses about 2.5 sigma at mass around 2 TeV in the diboson channels, which can be identified with new vector bosons as a hint for the new physics. It is shown that spontaneously broken conformal/scale symmetry prohibits new vector bosons decay to the Higgs, which is contrasted to the popular "equivalence theorem" valid only in a special limit not necessarily relevant to the 2 TeV mass. If the decay $V\to WH/ZH$ is not observed in the ongoing Run II of the LHC, then the 125 GeV Higgs can be a dilaton.
