Research in elementary particle physics is one of the most rewarding areas of research. It studies and discovers the laws
of Nauture. It is a field full of unknowns, excitments and new discoveries. The major goal of this course is to teach students
to use the Standard Model of strong and electroweak interactions
as the framework to analyze various problems related to particle Physics, with emphasison perspectives of future research in this field.
This course is a continuation of Particle physicsⅠ. Students interested in researches in theoretical or experimental particle physics are encouraged to take this course.
