Meet Ξcc+, a new charming proton-like particle discovered by smashing particles at CERN’s Large Hadron Collider beauty (LHCb) experiment.
Pronounced Xi-c-c-plus, the new fleeting particle contains 2 heavy charm quarks and 1 down quark, while the more familiar proton contains 2 up and 1 down quark.
Mass: ~4x that of the proton
Mean lifetime τ: 45 femtoseconds (4.5e-14 seconds)
Charge: +1
Of interest to: Theorists in quantum chromodynamics

1/nThe LHCb (Large Hadron Collider beauty) experiment is a particle physics detector at the Large Hadron Collider at CERN.
The 5600-tonne LHCb detector sits 100 metres below ground in the LGC tunnel near the town of Ferney-Voltaire, France.
The LHCb experiment uses a series of subdetectors to detect mainly forward particles – those thrown forwards by the collision in one direction.
