Tetraquark

The tiniest conceivable pieces of matter, quarks, are the easiest way to understand them. Iron atoms make up an iron object. These atoms are composed of protons and electrons. However, even if you dismantled those, all that would be left would be quarks. They exist in six different varieties and are amusingly referred to as "flavors." They have mass and spin. As well as being paired up and down, top and bottom, and charm and weird, these flavors are also grouped together. Crazy, huh? Actually, it gets stranger.

The tetraquark, a rare hadron composed of two quarks and two antiquarks, was discovered by scientists in 2021. Before its discovery, it was commonly believed to be impossible. Evidence from the Large Hadron Collider disproved the notion that the particles could ever form bonds with one another. The identification of the tetraquark will provide scientists with fresh resources to help them comprehend the strong interaction, which connects quarks to form neutrons and protons.
