我们计算了 LHC 的 2-希格斯双峰模型 (2HDM) 中希格斯玻色子与弱规范玻色子的相关产生的所有相关贡献​​,pp→ phi,其中 phi∈{h, H 0, A} 和 V∈{W, Z}。对于 W ψ 模式,这主要相当于标准模型 (SM) 横截面的简单重新缩放,而 Zψ 横截面取决于几个 2HDM 参数。因此,我们提出了目前最完整的 SM 预测的比率 σ W φ / σ Z φ 似乎是可能的新物理效应的敏感探针。我们研究了它对顶部和底部汤川耦合的数值依赖性,包括它们的符号。此外,我们考虑了示例性 2HDM 场景中的 Wψ/Zψ 比率,并简要讨论了增强状态下的影响。通过即将推出的包含 2HDM 效果的 vh@ nnlo 程序版本,对其他 2HDM 场景的类似研究将成为可能。
We present a calculation of all relevant contributions to associated production of a Higgs boson with a weak gauge boson in the 2-Higgs-doublet model (2HDM) at the LHC, pp→ ϕ, with ϕ∈{h, H 0, A} and V∈{W, Z}. While for the W ϕ mode, this mostly amounts to a simple rescaling of the Standard Model (SM) cross section, the Zϕ cross section depends on several 2HDM parameters. The ratio σ Wϕ/σ Zϕ, for which we present the currently most complete SM prediction, therefore appears to be a sensitive probe of possible New Physics effects. We study its numerical dependence on the top and bottom Yukawa couplings, including their sign. Furthermore, we consider the Wϕ/Zϕ ratio in exemplary 2HDM scenarios and briefly address the effects in the boosted regime. Analogous studies for other 2HDM scenarios will become possible with an upcoming version of the program vh@ nnlo which incorporates the 2HDM effects.
