Title: Dyons and Helicity Amplitudes
Host: Markus Luty
Room: 430
Abstract: Historically, the theory of monopoles and dyons has been plagued with nonlocality and broken Lorentz covariance, leading to difficulty in calculations of amplitudes involving magnetic currents. We present the Zwanziger 2-gauge formalism that addresses these problems, and use the spinor helicity method with twistors to greatly simplify results, such as in light-by-light scattering.
