The 'Doubly Strange' particle is a type of subatomic particle called Xi-cc++, which is composed of two charm quarks and one up quark.
The particle was discovered by scientists at CERN's Large Hadron Collider using data from the LHCb experiment. They analyzed collisions between protons at high energies and observed the decay of Xi-cc++ particles in the resulting debris.
The 'Doubly Strange' particle is unique because it is the first particle to be discovered that contains two charm quarks, which are one of the six types of quarks that make up all known matter. It is also the first time that scientists have observed particles containing two different types of quarks, known as double charm baryons.
This discovery provides further evidence for the standard model of particle physics, which describes the fundamental particles and forces that make up the universe. It also opens up new avenues for research and could potentially lead to a better understanding of the strong nuclear force that binds quarks together.
The discovery of the 'Doubly Strange' particle adds to our understanding of the building blocks of matter and the forces that govern them. It also helps to confirm the existence of predicted particles and provides valuable information for future studies in particle physics.
