Observation of the doubly charmed baryon $\it{\Xi}_{cc}^+$ with the LHCb Run 3 detector

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

The first observation of the doubly charmed baryon $\it{\Xi}_{cc}^+$ is reported through its decay to the $\it{\Lambda}_c^+ K^-\pi^+$ final state, with a statistical significance exceeding seven standard deviations. The observation is made using proton-proton collision data collected in 2024 with the LHCb …

Beam monitoring at the Large Hadron Collider beauty experiment

David Rolf

In particle physics, accelerators and detectors are continually improved to enhance the precision and functionality of experiments. An important part is to continue to ensure the safety of the experiment under the new conditions. The Large Hadron Collider beauty (LHCb) detector was …
