Seminar topic: “Chiral Magnetic Effect and Heisenberg-Landau Lagrangian”

Speaker: D. A. Shohonov

Abstract:

The connection between effective Heisenberg-Euler lagrangian at the order 1/m⁴ and Chiral Magnetic Effect known for massless particles is investigated. We consider the generalization of Heinseberg-Euler lagrangian incorporating both QED and QCD and calculate the induced vector current. Considering this current we establish a way to connect the obtained perturbative result with the Chiral Magnetic Effect. We formulate the transition rule from perturbative to non-perturbative regime leading to the correspondence with the well-known result for massless particles.
