Scientists using the Large Hadron Collider accelerator at CERN have discovered 5 new sub-atomic particles. These particles are baryons i.e. they are made up of three quarks (2 strange and 1 charm quarks). These particles decays from their class i.e. Omega-c-zero to another class of baryons i.e. Xi-c-plus and kaon.
 

Baryons: It is a composite subatomic particle made up of 3 quarks.

• It belongs to the hadron family and some of the most common examples are protons and neutrons.
• Baryons forms the majority of mass in the universe.

Other set of family members of hadron family are the mesons which are made up of 2 quarks and are called biquarks.
