这是 HL-LHC 物理研讨会最终报告 [1] 的五章中的第三章，以及 HE-LHC 的观点 [2]。它致力于研究在超越标准模型（BSM）物理过程中，LHC高光度（HL）相的潜力（定义为在14 TeV质心能量处获取的3 ab−1数据），以及未来可能升级的高能（HE）LHC（定义为在27 TeV质心能量处获取的15 ab−1数据）的潜力。我们考虑了各种各样的新物理模型，包括简化模型方式和更加依赖于模型的模型。来自理论和实验（ATLAS、CMS、LHCb）社区的一长串贡献已被收集并合并在一起，以对所考虑的对撞机上 BSM 物理的未来前景提供完整、广泛和一致的看法。除了考虑用于评估未来对撞机潜力的超对称简化模型和共振等通常的标准蜡烛之外，该报告还包含有关暗物质和暗扇区、长寿命粒子、轻夸克、惰性中微子、类轴子粒子、重标量、类矢量夸克等的结果。特别是在 HL-LHC 前景的研究中，特别关注探测器的升级、未来系统不确定性的评估以及新的实验技术。总体结论是，HL-LHC 除了允许在大多数新物理场景中将当前 LHC 质量和耦合范围扩展 20−50% 之外，还将能够约束并可能发现目前不受约束的新物理。此外，与 HL-LHC 相比，HE-LHC 的大多数可观测范围通常会增加一倍以上，这可能代表未来 TeV 规模新物理最终测试的良好候选设施。
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as 3 ab−1 of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as 15 ab−1 of data at a centre-of-mass energy of 27 TeV. We consider a large variety of new physics models, both in a simplified model fashion and in a more model-dependent one. A long list of contributions from the theory and experimental (ATLAS, CMS, LHCb) communities have been collected and merged together to give a complete, wide, and consistent view of future prospects for BSM physics at the considered colliders. On top of the usual standard candles, such as supersymmetric simplified models and resonances, considered for the evaluation of future collider potentials, this report contains results on dark matter and dark sectors, long lived particles, leptoquarks, sterile neutrinos, axion-like particles, heavy scalars, vector-like quarks, and more. Particular attention is placed, especially in the study of the HL-LHC prospects, to the detector upgrades, the assessment of the future systematic uncertainties, and new experimental techniques. The general conclusion is that the HL-LHC, on top of allowing to extend the present LHC mass and coupling reach by 20−50% on most new physics scenarios, will also be able to constrain, and potentially discover, new physics that is presently unconstrained. Moreover, compared to the HL-LHC, the reach in most observables will generally more than double at the HE-LHC, which may represent a good candidate future facility for a final test of TeV-scale new physics.
