论文摘要
我为$ h \ to \ ell^{+ell^{ - }γ$的标准模型预测的标准模型预测提供了新的结果，其中$ \ ell = e，μ$，以及以与Lepton Momenta相对应的光子方向定义的前进远不对称。结果取决于最终状态颗粒的能量和不变质量的切割。对于这些标准选择，降低了分支比率$ b（h \ to e \ bareγ）= 5.8 \ cdot 10^{ - 5} $和$ b（h \ toμ\ barμγ）= 6.4 \ cdot 10^{ - 5} $ \ Mathcal {a}^{（e）} _ {\ text {fb}} = 0.343 $和$ \ MathCal {a}^{（μ）} _ {\ text {fbe text {fb}} = 0.255 $。
I present new results for the Standard-Model predictions of the differential decay rates for $H\to \ell^{+} \ell^{-} γ$, where $\ell=e, μ$, and the forward-backward asymmetries defined in terms of the flight direction of the photon corresponding to the lepton momenta. The results dependend on the cuts on energies and invariant masses of the final state particles. For standard choices of these cuts the branching ratios $B(H\to e \bar e γ)=5.8\cdot 10^{-5}$ and $B(H\to μ\bar μγ)=6.4\cdot 10^{-5}$ as well as the forward-backward asymmetries $\mathcal{A}^{(e)}_{\text{FB}}=0.343$ and $\mathcal{A}^{(μ)}_{\text{FB}}=0.255$ have been found.
