  We propose a realistic regime to detect the light-induced topological band
gap in graphene via time-resolved angle-resolved photoelectron spectroscopy
(trARPES), that can be achieved with current technology. The direct observation
of Floquet-Bloch bands in graphene is limited by low-mobility,
Fourier-broadening, laser-assisted photoemission (LAPE), probe-pulse
energy-resolution bounds, space-charge effects and more. We characterize a
regime of low driving frequency and high amplitude of the circularly polarized
light that induces an effective band gap at the Dirac point that exceeds the
Floquet zone. This circumvents limitations due to energy resolutions and band
broadening. The electron distribution across the Floquet replica in this limit
allow for distinguishing LAPE replica from Floquet replica. We derive our
results from a dissipative master equation approach that gives access to
two-point correlation functions and the electron distribution relevant for
trARPES measurements.
