Abstract
Historically important in the development of the Standard Model (SM) of particle physics, rare kaon decays are still a privileged tool for looking beyond it. The main reasons to continue the study of rare kaon decays are to test the CKM quark-mixing and CP-violation paradigm, to make quantitative comparisons with the B sector, and to search for explicit violations of the SM. Current research on rare kaon decays focuses mostly on decays, which are predicted with good accuracy within the SM and beyond. Experimentally, these decays, especially that of the charged kaon, have a long history. Their theoretical importance is matched only by their experimental difficulty. This article reviews the progress of the past 10 years, describes the state of the art, and looks toward future perspectives.
期刊介绍：
The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation.
One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
