    "abstract": "The violation of local uncertainty relations is a valuable tool for detecting\nentanglement, especially in multi-dimensional systems. The orbital angular\nmomentum of light provides such a multi-dimensional system. We study quantum\ncorrelations for the conjugate variables of orbital angular momentum and\nangular position. We determine an experimentally testable criterion for the\ndemonstration of an angular version of the EPR paradox. For the interpretation\nof future experimental results from our proposed setup, we include a model for\nthe indeterminacies inherent to the angular position measurement. For this\nmeasurement angular apertures are used to determine the probability density of\nthe angle. We show that for a class of aperture functions a demonstration of an\nangular EPR paradox, according to our criterion, is to be expected.",
