Infrared identification of SiO maser sources toward the Sgr B2 molecular cloud

J, H, and K imaging observations have been made in order to identify infrared counterparts for 6 new SiO maser sources toward the Sgr B2 molecular cloud. Only two of these 6 new sources were previously identified with known objects in other catalogues: one with an OH/IR object, another with an IRAS point source. With the imaging observations, we find infrared counterparts for four of the objects: #1, #2, #4, and #7. These are late-type stars either nearby or near to the galactic center. The remaining two sources of which we could not find counterparts can be candidates of young stellar objects with SiO masers. However, it is highly possible that these two are late-type stars located behind the galactic-center molecular cloud, suffering from very high dust extinction.
