我们研究了各种对撞机搜索中产生的光赝标量的界限。因此，要特别注意质量区域 [3, 5] GeV 和 [9, 11] GeV，其中有意义的理论描述必须包括非微扰效应的估计，例如赝标量与 QCD 束缚态的混合。提供了允许处理相关更正的公式概要。它应该被证明对于解释未来 LHC 搜索光 CP 奇自旋 0 态是有用的。
We investigate the bounds on light pseudoscalars that arise from a variety of collider searches. Special attention is thereby devoted to the mass regions [3, 5] GeV and [9, 11] GeV, in which a meaningful theoretical description has to include estimates of non-perturbative effects such as the mixing of the pseudoscalar with QCD bound states. A compendium of formulas that allows to deal with the relevant corrections is provided. It should prove useful for the interpretation of future LHC searches for light CP-odd spin-0 states.
