The entire world is composed of elementary particles known as leptons and quarks. These particles will combine to form other particles like atoms, protons, and neutrons. Now, the researchers found a new type of particle, the pentaquark, thanks to the Large Hadron Collider.
Researchers are fascinated by the fact that these particles can interact with each other in exciting ways. By harnessing the power of the Large Hadron Collider, CERN researchers were able to detect a new type of particle. Named pentaquark this particle could play a significant role in future research, by allowing scientist to refine the theory of quarks, which is an essential part of the standard model of particle physics.
The theory of quarks was established in the middle of the 20th century as a way to explain the chaotic particles which were found in cosmic ray and collider experiments. The growing number of fundamental particles caused issues among physicists since they were forced to learn several names and principles.
Scientists discovered a new type of particle, the pentaquark
In the 1960s an American physicist named Murray Gell-Mann discovered several patterns which could be traced in the particle zoo. They were similar to the patterns observed by Dimitri Mendeleev during the elaboration of the periodic table of chemical elements. Gell-Mann created a new theory which inferred the existence of a new class of fundamental particles. As time passed, particle physicists learned more about a large number of particles which exist and concluded that smaller particles named quarks formed them.
At this point, there are six types of quarks which can be observed in the standard model. They are classified as up, down, strange, charm, bottom, and top. Antimatter equivalents called antiquarks usually accompany them. Quarks and antiquarks which are linked will form particles known as hadrons.
The new data expands the first pentaquark theory that appeared in 2015. The new study has shown that the first pentaquark was composed of two smaller pentaquarks which were so similar as they seemed to be a single particle.
