Abstract

A novel approach is proposed to demonstrate the two-photon Breit-Wheeler process by using collimated and wide-bandwidth γ-ray pulses driven by 10-PW lasers. Theoretical calculations suggest that more than 3.2×108 electron-positron pairs with a divergence angle of 7° can be created per shot, and the signal-to-noise ratio is higher than 103. The positron signal, which is roughly 100 times higher than the detection limit, can be measured by using the existing spectrometers. This approach, which could demonstrate the ee+ pair creation process from two photons, would provide important tests for two-photon physics and other fundamental physical theories.
