论文摘要
超越SM的主要动机之一是理论预测和观察到哑光的异常磁矩之间的差异。减轻理论与实验之间的这种张力，并同时满足Lepton风味侵犯数据的界限是一项艰巨的任务。在本文中，我们将具有Yukawa结构的两个Higgs Doublet模型考虑为X型X型Higgs Doublet模型的扰动。鉴于该模型，我们探索了穆恩异常和轻子味违规，以及来自B物理学，理论约束，Electroweak可观察数据和对撞机数据的约束，这些数据可以显着限制模型参数空间。我们发现，在该模型的框架内，可以通过所有约束获得允许的区域，该区域可以为观察到的MUON异常提供解释，同时也可以预测Lepton风味违规的有趣特征。此外，我们认为违反低质量CP-ODD标量的风味衰减，以探测LHC将来运行时允许的参数空间。通过简单的基于切割的分析，我们表明该参数空间的一部分可以用显着性$>5σ$进行探测。我们还提供人工神经网络分析，无疑可以显着改善我们的基于剪切的结果。
One of the main motivations to look beyond the SM is the discrepancy between the theoretical prediction and observation of anomalous magnetic moment of muon. Alleviating this tension between theory and experiment and satisfying the bounds from lepton flavor violation data simultaneously is a challenging task. In this paper, we consider generalised Two Higgs Doublet Model, with a Yukawa structure as a perturbation of Type X Two Higgs Doublet Model. In view of this model, we explore muon anomaly and lepton flavor violation along with constraints coming from B-physics, theoretical constraints, electroweak observables and collider data which can restrict the model parameter space significantly. We find that within the framework of this model it is possible to obtain regions allowed by all constraints, that can provide an explanation for the observed muon anomaly and at the same time predicts interesting signatures of lepton flavor violation. Furthermore, we consider the flavor violating decay of low-mass CP-odd scalar to probe the allowed parameter space at future runs of the LHC. With simple cut-based analysis we show that part of that parameter space can be probed with significance $> 5 σ$. We also provide Artificial Neural Network analysis which definitely improves our cut-based results significantly.
