Dual coherent particle emission as generalized Cherenkov - like effect in high-energy particle collisions

In this paper we introduce a new kind of nuclear/hadronic coherent particle production mechanism in high-energy collisions called \emph{dual coherent particle emission (DCPE)} which takes place when the phase velocities of the emitted particle v_{Mph} and that of particle source v_{B_1ph} satisfy the dual coherence condition: v_{Mph} <= v_{B_1ph}^-1. The general signatures of the DCPE in the nuclear and hadronic media are established and some experimental evidences are given.
