MEASUREMENT OF THE MAGNETIC AND ELECTRIC DIPOLE MOMENTS OF THE $\LAMBDA$ BARYON AT LHCB
… most profound and unresolved questions in modern physics is why the Universe is composed predominantly of matter, with negligible antimatter. This imbalance suggests the existence of processes that violate the fundamental symmetry between matter and antimatter, the so-called CP symmetry. However, …
