论文摘要
我们提出了从Quark和Lepton风味物理学寻找类似轴的颗粒（ALP）的新观点：与时间相关的CP不对称的测量值$ B^0 \至K_S^0π^0γ$，以及$ b_s \ to e^\pmμ^\ mp $ decAy的分支比例的分支率，以及MOM and and and and。 In the mass range of sub-GeV, accessible by the flavorful ALPs search, the experimental sensitivity for these flavor observables reaches the maximum at around the pion mass scale (called the {\it sweetest} spots), where a couple of loopholes (unexplored regions) for the ALP parameter space have heretofore been present, because of an unavoidable contamination with pion background events.所提出的互补探针可以精确地确定在这些{\ it最甜的}斑点/漏洞上与光子与光子的耦合，并将大大帮助覆盖ALP搜索中的整个参数空间，包括将来的当前漏洞。
We propose new perspective in searching for axion-like particles (ALPs) from quark and lepton flavor physics: measurements of the time-dependent CP asymmetry in $B^0 \to K_S^0 π^0 γ$ and the branching ratio of $B_s \to e^\pm μ^\mp$ decay possess, along with the anomalous magnetic moment of muon. In the mass range of sub-GeV, accessible by the flavorful ALPs search, the experimental sensitivity for these flavor observables reaches the maximum at around the pion mass scale (called the {\it sweetest} spots), where a couple of loopholes (unexplored regions) for the ALP parameter space have heretofore been present, because of an unavoidable contamination with pion background events. The proposed complementary probes can precisely determine the ALP coupling to photon at these {\it sweetest} spots/loopholes, and will significantly help cover whole parameter spaces in the ALP search including the present loopholes in the future.
