论文摘要
像颗粒(阿尔卑斯山)一样的轴突属于一个动机的颗粒类别,这是更完整的紫外线理论的一部分。在这项工作中,我们启动并介绍了在模型独立的有效拉格朗日方式中,在重子手性扰动理论(HHCHIPT)中包含此类阿尔卑斯山或常规轴。这样的框架非常适合研究重型至重夸克风味的过渡。对于轻型阿尔卑斯山,ALP耦合(或其组合)的极限结果与ALP质量无关。对相应的重型伪内膜中的重型媒介中的辐射和松弛衰变将能够在阿尔卑斯山,尤其是对角线耦合上提供一些最严格的约束。
Axion Like Particles (ALPs) belong to a well motivated class of particles which are part of a more complete UV theory. In this work, we initiate and present the inclusion of such ALPs or the conventional axions in the Heavy Hadron Chiral Perturbation Theory (HHChiPT) in a model independent effective lagrangian way. Such a framework is well suited for studying heavy to heavy quark flavour preserving transitions. For light ALPs, the limits on the ALP couplings (or their combinations) turn out to be independent of ALP mass. Radiative and leptonic decays of heavy vector mesons to corresponding heavy pseudoscalar mesons will be able to provide some of the most stringent constraints on ALPs, particularly the diagonal couplings.
