Three new Exotic subatomic particles discovered with the Large Hadron Collider
Tags: Science and Technology
The Large Hadron Collider beauty (LHCb) experiment has discovered three never-before-seen particles.
What is the discovery?
CERN, (European Organization for Nuclear Research) was investigating the slight differences between matter and antimatter by studying a type of particle called the “beauty quark”, or “b quark”.
The three “exotic” particles, a new kind of “pentaquark” and the first-ever pair of “tetraquarks” were found.
These are a kind of new hadrons.
The discovery will help physicists understand how quarks bind together in these composite particles.
What are Quarks?
Quark is a fundamental component of matter and is defined as an elementary particle.
These quarks combine to produce composite particles called hadrons.
They usually combine together in groups of twos and threes to form hadrons.
The most stable of these are neutrons and protons which are components of the atomic nucleus.
They can also combine into four-quark and five-quark particles, called tetraquarks and pentaquarks.
These exotic hadrons were predicted by theorists nearly six decades ago.
Tetraquarks and Pentaquarks
Atoms contain smaller particles called neutrons and protons, which are made up of three quarks each.
Most of the exotic hadrons discovered in the past two decades are tetraquarks or pentaquarks.
They contain a charm quark and a charm antiquark.
