Electron-Positron Plasma Drop Formed by Ultra-Intense Laser Pulses    [PDF]

Inga Kuznetsova, Johann Rafelski
We study the initial properties, and positron annihilation within a small electron-positron plasma drop formed by intense laser pulse energy initiated QED cascade in general far below the chemical (particle yield) equilibrium. We find that the available electrons and positrons equilibrate kinetically, yet despite relatively high particle density the electron-positron annihilation is very slow suggesting a rather long lifespan of the plasma drop.
