Abstract

We study the initial properties and positron annihilation within a small electron-positron plasma drop formed by intense laser pulse energy. Such QED cascade generated plasma is, 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 life span of the plasma drop.
