Quark

Physicists at CERN have discovered an exotic new particle that’s quite charming. Known as Tcc+, the particle belongs to a rare class called tetraquarks, and its unusual composition makes it the longest-lived exotic hadron found so far.

A subatomic particle has been found switching between matter and antimatter, in Large Hadron Collider data. It turns out an unfathomably tiny weight difference between two particles could have saved the universe from annihilation soon after it began.

CERN’s Large Hadron Collider probes the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s early days, the discovery hints at the existence of new particles or forces beyond the Standard Model.

Astrophysicists have found evidence of quark matter at the heart of compact stars. Combining recent theoretical calculations with astrophysical observations, the researchers found that the most massive neutron stars most likely have “quark cores.”

​Researchers at CERN have discovered a doubly charming new particle, which has long been theorized to exist. Named Ξcc++(Xicc++), the particle is the first found to contain two heavy quarks, and its confirmation should pave the way to a better understanding of the fundamental forces of physics.

​Glueballs are long sought-after exotic particles, created from pure force. Researchers at TU Wien claim to have discovered this mysterious particle in the remnants of collisions in particle accelerators.

A study of 5.02 TeV proton-lead collisions at the Large Hadron Collider suggest that a new form of matter is being created.
