In the quasistatic regimes of nonlinear Breit-Wheeler and trident paircreation, the rates can exhibit a non-analytic dependency on the fundamentalcoupling of quantum electrodynamics (QED), in a form similar to Schwingervacuum pair creation. To reach this tunneling regime requires satisfyingcompeting requirements: high intensity but low strong-field parameter withsufficient pair creation to be observed. Using a locally monochromaticapproach, we identify the parameter regime where tunneling pair-creation couldbe measured for the first time in experiment. Studying several scenarios ofcollisions with focussed Gaussian pulses, including a bremsstrahlung and aninverse Compton source for nonlinear Breit-Wheeler and a Gaussian electron beamfor nonlinear trident, we find the position of the tunneling parameter regimeto be well-defined and robust.
