Abstract

In this paper, we perform an analysis of the large set of microlensing events detected so far toward the galactic center, with the purpose of investigating whether some of the dark lenses are located in galactic globular clusters. We found that in four cases some events might have occurred due to lenses located in the globular clusters themselves. We also give a rough estimate for the average lens mass of the subset of events being highly aligned with galactic globular-cluster centers and find that, under reasonable assumptions, the deflectors could possibly be either brown dwarfs, M-stars, or stellar remnants.
