轻CP奇Higgs粒子辐射$Υ$衰变的新约束

Updated constraints from radiative $Υ$ decays on a light CP-odd Higgs

F. Domingo

摘要:

在许多新物理学模型中,可能存在一个轻的CP奇希格斯态,这可能导致在底偶素扇区中可观察到的效应。辐射$Υ$衰变通过这样的赝标态和可能的混合与$η_b^0$状态的实验界限进行审查。结合这两种效应,我们在小光子能量$BR(Υ\toγ\,τ^+τ^-)$的极限下,即在赝标质量范围$\sim8-10$ GeV内,对CP奇希格斯粒子的性质进行了约束.

英文摘要:

The possible existence of a light CP-odd Higgs state in many new-physics models could lead to observable effects in the bottomonium sector. Experimental bounds on radiative $Υ$ decays through such a pseudoscalar state and possible mixings with the $η_b^0$ states are reviewed. Combining these two effects, we set constraints on the properties of the CP-odd Higgs in the limit of small photon energy of $BR(Υ\toγ\,τ^+τ^-)$, that is on the pseudoscalar mass-range $\sim8-10$GeV.
