弱电真空稳定性和上升拐点的次-次领先阶分析
Next-to-Next-Leading Order analysis of electroweak vacuum stability and rising inflection point
摘要:
我们分析了与规范无关的观测量与两个固定配置的标准模型(SM)的潜力(外推到高能量在下一个到下一个到领先的顺序(NNLO)):i)的顶部质量的值,确保稳定的SM电弱真空和ii)希格斯势的值在一个上升的拐点。我们详细研究和重新评估的实验和理论的不确定性,困扰他们的决心,保持活着的可能性SM是稳定的,并研究应用这种配置的模型原始通货膨胀。
英文摘要:
We show an analysis on the gauge-independent observables associated with two stationary configurations of the Standard Model (SM) potential (extrapolated to high energy at Next-to-Next-to-Leading-Order (NNLO)): i) the value of the top mass ensuring stability of the SM electroweak vacuum and ii) the value of the Higgs potential at a rising inflection point. We examine in detail and reappraise the experimental and theoretical uncertainties which plague their determination, keeping alive the possibility for the SM of being stable and studying applications of such configuration to models of primordial inflation.
