Summary

Story summary

Researchers at CERN's Large Hadron Collider discovered a particle, ?cc+, with two charm quarks and one down quark.
The ?cc+ is four times heavier than a proton.
The discovery was presented at the Moriond conference using the upgraded Large Hadron Collider beauty (LHCb) detector.
The LHCb Collaboration confirmed the finding at 7 sigma, surpassing the five sigma discovery threshold.
The University of Manchester played a significant role in this research.
