NMSSM中Higgs到Higgs衰变的基准面

Benchmark Planes for Higgs-to-Higgs Decays in the NMSSM

Ulrich Ellwanger, Cyril Hugonie

摘要:

在次极小超对称标准模型中,我们给出了具有胶子熔合截面的基准面(或线),这些基准面包括$H\to h+H_{S}$、共振Higgs对和三重Higgs产生、$A \to h+(A_S \to γγ)$、$A \to Z+ h$和$A \to Z+ H_{S}$过程.此外,我们提出了新的搜索$H\to h+(H_{S} \to t\bar{t})$,$A \to Z+ (H_{S}\to h+h)$和$A \to Z+ (H_{S}\to t\bar{t})$可能的截面。这些允许实验合作在未来验证哪些搜索通道覆盖参数空间的尚未探索的区域。三线性希格斯耦合和Higgs-Z耦合的主要贡献的表达式进行了讨论,它允许确定一个给定的最终状态的主导过程。

英文摘要:

We present benchmark planes (or lines) with cross sections via gluon fusion for the processes $H\to h+H_{S}$, resonant Higgs pair and triple Higgs production, $A \to h+(A_S \to γγ)$, $A \to Z+ h$ and $A \to Z+ H_{S}$ within the Next-to-Minimal Supersymmetric Standard Model. Moreover we propose new searches for $H\to h+(H_{S} \to t\bar{t})$, $A \to Z+ (H_{S}\to h+h)$ and $A \to Z+ (H_{S}\to t\bar{t})$ for which possible cross sections are given. These allow the experimental collaborations to verify in the future which search channels cover yet unexplored regions of the parameter space. Expressions for the dominant contributions to trilinear Higgs couplings and Higgs--Z couplings are discussed which allow to identify the dominant processes contributing to a given final state.
