Why in News?
● In March 2017, Scientists of Large Hadron Collider accelerator at CERN (European Organisation for Nuclear
Research) found five new sub-atomic particles.
More on the News
●The newly discovered particles are high-energy versions of the omega-c baryon, a particle made up of two
strange quarks and one charm quark
●Omega-c-zero is a part of the same family of protons and neutrons, the so-called baryons, because they have
three quarks, the fundamental building blocks of matter.
●These particle states are named, according to the standard convention, Omega-c-zero (3000), Omega-c-zero
(3050), Omega-c-zero (3066), Omega-c-zero (3090) and Omega-c-zero (3119). The numbers indicate their
masses in megaelectronvolts (MeV).
● Characteristic numbers are used to identify the properties of a specific particle and the determination of
their theoretical significance.
