CERN scientists have discovered a new kind of particle called pentaquark.
American physicists Murray Gell-Mann and Georg Zweig first proposed the existence of pentaquarks in the 1964. Prof. Gell-Mann who received the Nobel Prize in 1969 coined the term “quark”.
The discovery was made by a team working on one of the four experiments at the Large Hadron Collider
- Quarks are a group of subatomic particles that acted as building blocks for another form of matter existed. These particles were thought to exist in varied states.
- One of these alternative states was the pentaquark, which was made up of four quarks and an antiquark, or a quark’s anti-matter.
- Studying pentaquarks may help scientists to understand better how ordinary matter is constituted, from which we’re all made.
- This discovery may provide hints as to what happens when giant stars collapse.
- The European Organization for Nuclear Research or CERN s a European research organization that operates the largest particle physics laboratory in the world.
- At CERN most experiments are conducted at Large Hadron Collider (LHC) which is world’s largest and powerful particle collider. It lies in tunnel which is 27 km in circumference.
- CERN provides the particle accelerators and other infrastructure needed for high-energy physics research
- CERN is also the birthplace of the World Wide Web
