Abstract

The QED scattering amplitude in a chiral medium characterized by a constant chiral chemical potential μ₅ and chiral magnetic conductivity b₀ is analyzed. We show the emergence of the resonant behavior in 1 → 2, 2 → 2, and 2 → 3 processes. We compute the rates of paradigm 1 → 2 processes that determine the widths of quasi-stationary fermion and photon states in the medium. We elucidate the origin of these resonances, the conditions of their emergence, and the physical principles of their regularization.

具有手性化学势和手性导电性的QED散射振幅和共振过程

分析了具有恒定手性化学势μ5和恒定手性导电性b0的手性介质中的QED散射振幅。我们展示了在1→2、2→2和2→3过程中共振行为的出现。我们计算了模式1→2过程的速率，该过程决定了介质中准稳态费米子和光子态的宽度。我们阐明了这些共振的起源，它们出现的条件，以及它们正则化的物理原理。

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
