Charged gravitational instantons: extra CP violation and charge quantisation in the Standard Model
arXiv:1808.01796 · doi:10.1140/epjc/s10052-019-6577-y
Abstract
We argue that quantum electrodynamics combined with quantum gravity results in a new source of CP violation, anomalous non-conservation of chiral charge and quantisation of electric charge. Further phenomenological and cosmological implications of this observation are briefly discussed within the standard model of particle physics and cosmology
