By applying color criteria to deep Spitzer IRAC and MIPS mosaics, we have identified 17 possible mid-infrared-selected counterparts to the submillimeter galaxies in the CUDSS 14 hour field.Ten of the 17 counterparts are not the same as those previously identified at shorter wavelengths. We argue that 8.0 micron selection offers a better means for identifying counterparts to submillimeter galaxies than near-infrared or optical selection. Based on the panchromatic SEDs, most counterparts appear to be powered by ongoing star formation, but power-law fits to the SEDs suggest that five objects in the 8.0 micron-selected counterpart sample harbor dominant AGNs; a sixth object is identified as a possible AGN.The 3.6-8.0 micron colors of the infrared-selected counterparts are significantly redder than the general IRAC galaxy population in the CUDSS 14 hour field.Support for this work was provided by NASA through Contract Number 1256790 issued by JPL/Caltech.
