Possible generation of $\pi$-condensation in a free space by collisions between photons and protons

Abstract

A sharply peaked structure is found in the angular distribution of emitted ${\pi }^{+}$ mesons from the photon-proton collisions. It offers a possible way for generating a ${\pi }^{+}$-condensation in free space. To make the stimulated emission of ${\pi }^{+}$-mesons efficient, a ring resonator is designed.
