Pulsar Kick by the Chiral Anisotropy Conversion

We discuss a novel mechanism for the proto-neutron star acceleration assisted by the chiral separation effect which induces an axial vector current in a dense medium. We consider the process of neutrinos scattering off the background axial vector cur

Implications of the helicity conservation for on-shell and off-shell chirality production

Autor: Fukushima, Kenji, Yu, Chengpeng

We analyze the helicity conservation following from the axial Ward identity for the massless fermion. We discuss the pair production of a fermion, $\ell$, and an anti-fermion, $\bar{\ell}$, from the annihilation process of photons, $\gamma$'s and con

Evolution of chirality in a multiphoton pair production process

Autor: Yu, Chengpeng

Publikováno v: Phys.Rev.D 108 (2023) 11, 116009

Recent years, multiphoton pair production has become one of the most promising approaches to investigate the Schwinger effect. However, the production and evolution of chirality, a key topic in the study of this effect, has not been thoroughly consid
