Laser Driving Highly Collimated $\gamma$-ray Pulses for the Generation of ${\mu }^{-}{\mu }^{+}$ and $e^{-}{e}^{+}$ Pairs in $\gamma -\gamma$ Collider

J. Q. Yu, R. H. Hu, Z. Gong +6

A scheme to generate highly collimated $\gamma$-ray pulse is proposed for the production of muon and electron pairs in $\gamma -\gamma$ collider. The $\gamma$-ray pulse, with high conversion efficiency…
