根据新的CDMS结果对Higgs不可见宽度的影响

Implication on Higgs invisible width in light of the new CDMS result

Kingman Cheung, Tzu-Chiang Yuan

摘要:

在假设暗物质粒子自旋无关截面的超对称性支配图是由希格斯玻色子交换引起的情况下,基于CDMSII合作组的新结果,得到了Higgs-暗物质耦合的上限.然后我们得到了希格斯玻色子不可见宽度的上限,数值上对于$m_h \simeq 120 - 180$ GeV,它小于20-120 MeV.对希格斯玻色子搜索的影响也进行了讨论。

英文摘要:

With the assumption that the dominant diagram in supersymmetry for the spin-independent cross section of the dark matter particle is due to Higgs boson exchange, we obtain an upper limit on the Higgs-dark-matter coupling based on the new result of the CDMSII Collaborations. We then obtain an upper limit on the invisible width of the Higgs boson, numerically it is less than 20-120 MeV for $m_h \simeq 120 - 180$ GeV. Implications for Higgs boson search are also discussed.
