We consider kinetic theory with spin (or helicity) degrees of freedom and its application. The spin plays an important role when particles are in a large magnetic or rotational field. This is the case in heavy-ion collision experiments, where the peripheral collision is expected to produce these large fields. In such a situation, anomalous transport phenomena (e.g., chiral magnetic and vortical effects) will occur due to the coupling between the spin and the magnetic field or the vorticity of fluid. We construct the kinetic theory for massless and massive particles based on quantum field theory and show the novel transport phenomena caused by interactions.
