论文摘要
具有Coleman-Weinberg类型有效电位的标量场在粒子物理的各种情况下都产生，并且是讨论宇宙膨胀的有用框架。根据基于马尔可夫链蒙特卡洛分析的最新研究，这种有效潜力的系数受到宇宙学数据的严重限制。我们调查了该观察结果对标准模型以外的物理的影响，重点是基于$ u（1）_x $扩展标准模型的通货膨胀模型，作为一个良好的示例。我们检查了在139 fb $ {}^{ - 1} $集成的光度的139 fb $ {}^{ - 1} $ Intemation Luminosity的参数区域，并表明该模型参数可以受到近来的高光度LHC实验的进一步限制。我们还评论了可能的再加热机制和这种情况的暗物质候选者。
A scalar field having the Coleman-Weinberg type effective potential arises in various contexts of particle physics and serves as a useful framework for discussing cosmic inflation. According to recent studies based on the Markov chain Monte Carlo analysis, the coefficients of such an effective potential are severely constrained by the cosmological data. We investigate the impact of this observation on the physics beyond the Standard Model, focusing on an inflationary model based on the $U(1)_X$-extended Standard Model as a well-motivated example. We examine the parameter region that is not excluded by the Large Hadron Collider (LHC) Run-2 at 139 fb${}^{-1}$ integrated luminosity, and show that the model parameters can be further constrained by the High-Luminosity LHC experiments in the near future. We also comment on the possible reheating mechanism and the dark matter candidates of this scenario.
