Hadrons mean particles on which strong force acts. Hadrons are grouped to baryons and mesons. Most of the visible mass in our universe is due to the hadron mass.
In the lecture, quarks which constitute hadrons are explained. Baryons and mesons are grouped based on the symmetry. Explanation is given on what roles gluons play in quantum chromodynamics which is the theory of strong interaction. Partons and structure functions in high energy reaction are also explained. Weak interaction of hadrons is described in the framework of standard model of particle physics. Symmetry breaking is explained. Origin of hadron mass and quark-gluon plasma are also explained.
The purpose of the lecture is to let the students understand hadrons which constitute the present universe. It is also important to understand Quantum Chromo Dynamics which is the theory of strong interaction. Another purpose is to let the students understand which kinds of experiments have contributed to the hadron physics.
[Objectives] By taking this course, students will understand the basics of hadron physics. Students will understand the features of strong interaction, the description of hadrons based on quarks, and features of quantum chromodynamics.
[Topics] The topics are strong interaction, quark flavors, generations, quark model and description of hadrons, strange quarks and hyperons, gluons, elastic scattering, deep inelastic scattering, structural functions, parton model, weak interaction, source of mass, quark- gluon plasma, etc.
