A heavier version of the proton, has been discovered by a team at the nuclear research laboratory CERN
It was found using the newly upgraded Large Hadron Collider (LHC) as part of its latest โbeautyโ experiment, known as LHCb.
Scientists spotted the particle amid a spray of debris created by colliding particles at the facility near Geneva, Switzerland.
The particle has been called
Xi-cc-plus,
(written as ฮccโบ),
and is four times as heavy as a normal proton.
Its extra mass comes from the fact that it is made from heavier building blocks, known as quarks.
A regular proton contains two "up" quarks and one "down".
However, the Xi-cc-plus proton contains two โcharmโ quarks instead of the lighter "up" quarks.
Because of this, it has been dubbed a โdoubly charmed baryonโ.
(A baryon is a subatomic particle, including protons and neutrons, that is made of three quarks.)
Scientists were able to deduce its existence when they spotted three lighter particles created as by-products when the Xi-cc-plus proton decayed.
It is the first new particle detected by the upgraded LHC, whose first iteration astonished the scientific world with the discovery of the Higgs boson in 2012.
