Dual coherent particle emission as generalized two-component Cherenkov-like effect

In this paper we introduce a new kind of coherent particle production mechanism called dual coherent particle emission (DCPE) as the generalized two-component Cherenkov-like effect, which takes place when the phase velocity of emitted particle νMph and the particle source phase velocity νB1ph satisfy a specific DCPE condition: νMphνB1ph ≤ 1. The general signatures of the DCPE in dielectric, nuclear and hadronic media are established and experimental evidence is presented. (authors)
