  The crown jewel of particle physics, the Standard Model (SM), has withstood
numerous experimental trials. However, there are still some observations it
cannot explain. Examples such as dark matter and the matter-antimatter
imbalance in the Universe come to mind. The SM may be extended, by including
additional particles and interactions, so as to explain such phenomena. These
new particles and interactions are collectively referred to as "new physics"
(NP), and the results covered by this article provide a promising lead for
their discovery.
