在LHC处的Radio-higgs混合态与KK对产生和衰变的贡献

Radion-higgs mixing state at the LHC with the KK contributions to the production and decay

Hirohisa Kubota, Mihoko Nojiri

摘要:

本文研究了Randall-Sundum模型中物质和规范场共存的Higgs-Radion系统。我们考虑到Kalza-Klein(KK)环修正的希格斯和raidion耦合的规范玻色子。受2011年大型强子对撞机数据的启发,在125 GeV处发现了希格斯玻色子的信号,我们将希格斯玻色子混合态的质量本征态之一固定在125 GeV处,并扫描了2011年数据中没有排除的所有其他参数。我们发现125 GeV标量粒子的分支比明显大于或小于标准模型希格斯粒子的分支比的参数区域。预测的比值Br(ZZ)/Br(gamma gamma)也可能与SM希格斯玻色子的不同。

英文摘要:

In this paper we study the higgs-radion system of the Randall-Sundum model where matter and gauge fields live in the bulk. We take into account the Kalza-Klein(KK) loop correction for the higgs and the raidion coupling to the gauge bosons. Inspired by the LHC data in 2011 where a sign of the higgs boson has been seen at 125 GeV, we fix the one of the mass eigenstate of the higgs-radion mixed state at 125 GeV, and scan over all the other parameters which have not been excluded by the 2011's data. We find the region of parameters where the scalar particle at 125 GeV have branching ratio larger or smaller than that of the Standard Model(SM) higgs significantly. The predicted ratio Br(ZZ)/Br(gamma gamma) also may be different from that of the SM higgs boson.
