Hadron
Hadron
Hadron (/ˈhædrɒn/; from Greek: ἁδρός, hadrós, 'stout, thick') is a term used in Particle Physics to describe any of the composite particles made of quarks, antiquarks, and gluons.
Etymology
The term "Hadron" was coined by Lev Okun in a 1962 conference in Geneva. The name is derived from the Greek word "hadrós", which means "stout" or "thick". This is in reference to the 'strong' interaction between the particles that make up a hadron.
Types of Hadrons
There are two types of hadrons: Baryons and Mesons. Baryons, such as protons and neutrons, are made up of three quarks. Mesons, on the other hand, are made up of a quark and an antiquark.
Baryons
Baryons are a type of hadron that are made up of three quarks. The most well-known baryons are the proton and the neutron, which make up the nuclei of atoms.
Mesons
Mesons are a type of hadron that are made up of a quark and an antiquark. They are often produced in high-energy collisions, such as those in particle accelerators.
