Two particle correlations are used to extract information about the\ncharacteristic size of the system in proton-proton and heavy ion collisions.\nThe size of the system can be extracted from the Bose-Einstein quantum\nmechanical effect for identical particles. However there are also long range\ncorrelations that shift the baseline of the correlation function from the\nexpected flat behavior. A possible source of these correlations is the\nconservation of energy and momentum, especially for small systems, where the\nenergy available for particle production is limited. A new technique, first\nused by the STAR collaboration, of quantifying these long range correlations\nusing energy-momentum conservation considerations is presented in this talk.\nUsing Monte Carlo simulations of proton-proton collisions at 900 GeV, it is\nshown that the baseline of the two particle correlation function can be\ndescribed using this technique.\n
