论文摘要
自发崩溃模型旨在通过将波功能的崩溃作为一种抑制宏观叠加的本体客观机制来解决量子力学的测量问题。特别是，崩溃的强度取决于系统的质量。风味振荡系统（例如中性介子）具有不同质量状态的叠加，因此可以使用自发崩溃模型的有效性来测试。最近，已经表明，质量比例的CSL模型会导致中性介子振荡的指数阻尼，然而，在当前的加速器设施中不足以观察到。在这封信中，我们研究了混合$ \ MATHCAL {CP} $对称性的违规会改变对风味振荡及其可观察性的自发崩溃影响。
Spontaneous collapse models aim at solving the measurement problem of quantum mechanics by introducing collapse of wave function as an ontologically objective mechanism that suppresses macroscopic superpositions. In particular, the strength of collapse depends on the mass of the system. Flavor oscillating systems such as neutral mesons feature superpositions of states of different masses and, hence, could be used to test the validity of spontaneous collapse models. Recently, it has been shown that the mass-proportional CSL model causes exponential damping of the neutral meson oscillations which, however, is not strong enough to be observed in the present accelerator facilities. In this Letter, we study how the violation of the $\mathcal{CP}$ symmetry in mixing changes the spontaneous collapse effect on flavor oscillations and its observability.
