A prominent detection strategy in leading direct dark matter searches, such as XENON and LUX, is based on scintillation in liquid xenon. The scintillation photons are used to reconstruct possible scattering events between the hypothesized weakly-interacting dark mater particles and the xenon targets, both by nuclear (possible signal) and by electronic (background) recoils. We still lack some fundamental understanding of these processes, and specifically of coherent effects such as super-radiance. At low recoil energies, current reconstruction and background rejection capabilities may be significantly improved by considering the anisotropic emission of scintillation photons, with prospects of constraining the incoming particle direction. The Direxeno experiment was designed and built to this end, with a scientific goal of measuring the direction of individually emitted scintillation photons. In this talk I will briefly review the latest advancements and future plans for Direxeno.
