Direct CP violation in: Standard Model status
H Gisbert, A Pich - Reports on Progress in Physics, 2018 - iopscience.iop.org
In 1988 the NA31 experiment presented the first evidence of direct CP violation in the decay
amplitudes. A clear signal with a statistical significance was later established with the full …
