Abstract
This project mainly describe the introduction to chiral perturbation theory for strong
interaction at low energy level and deals with quantum chromodynamics and its global
symmetry in the concept of chiral limit.
This project also describe the commutator and anti commutator of charge operators of
quarks in hadron spectrum. Then we will construct e ective Lagrangian for both global
and local symmetry and it show e ective Lagrangian is invariant under Su(3)L Su(3)R
symmetry transformation.Then we calculate currents from e ective Lagrangian.
Finally, by discussing e ective Lagrangian and weingers power counting scheme we
will see application of quantum chromodynamics,especially pion decay
