A New Particle Discovered at CERN!
A New Discovery Announced Might Help Understand What formed Our Universe.
Scientists at the European Organization for Nuclear Research (CERN) this week announced their discovery of a new particle dubbed Xicc++. This discovered particle is a baryon. And a baryon is a subatomic particle consisting of quarks. The most familiar baryons known by the public are protons and neutrons. However, this baryon differs from others since it includes 2 charm quarks and one up quark. Moreover, scientists observed Xicc++ at an energy of 13 TeV and its mass is 3621 MeV. That’s four times heavier than a proton.
Nevertheless, Xicc++ was predicted before. But scientists never observed it experimentally until the last experiment performed at the Large Hadron Collider (LHC). It is an unstable particle which exists only for a fraction of a second before decaying into lighter particles.
What is the LHC?
LHC is a particle accelerator built by CERN. This ring-shaped accelerator is located in a 27 km tunnel beneath the French-Swiss border. The role of the LHC is to smash protons together at approximately the speed of light and then analyze the nature of the particle resulted in that collision. According to scientists, this helps them discover the building blocks of the universe and what matter formed it. Moreover, the LHC is famous for observing the Higgs Boson, a particle that gives mass to other particles.
What does the newly discovered particle mean to physicists?
Concerning the new observed particle, the new spokesperson of the LHCb collaboration Giovanni Passaleva says: “Finding a doubly heavy-quark baryon is of great interest as it will provide a unique tool to further probe quantum chromodynamics, the theory that describes the strong interaction, one of the four fundamental forces.” He also adds that “Such particles will thus help us improve the predictive power of our theories.” – source.
Moreover, the former spokesman of the collaboration, Guy Wikinson says: “In contrast to other baryons, in which the three quarks perform an elaborate dance around each other, a doubly heavy baryon is expected to act like a planetary system, where the two heavy quarks play the role of heavy stars orbiting one around the other, with the lighter quark orbiting around this binary system.” – source.
How LHC discoveries contribute to Science?
The purpose from the LHC is to understand the Universe: What was it like at the time of the Big Bang. More aims are to analyze results to uncover mysteries about the possibility of the existence of other universes, dark matter, String Theory, monopole magnets, new subatomic particles, supersymmetry, and many other hidden facts that contribute to the explanation of life and how it came to exist.
