We analyze 8 sources with strong mid-infrared excesses in the 13 Myr-olddouble cluster h and chi Persei. New optical spectra and broadband SEDs (0.36-8mu_m) are consistent with cluster membership. We show that material with T ~300-400 K and Ld/Lstar ~ 10^-4-10^-3 produces the excesses in these sources.Optically-thick blackbody disk models - including those with large inner holes- do not match the observed SEDs. The SEDs of optically-thin debris disksproduced from terrestrial planet formation calculations match the observationswell. Thus, some h and chi Persei stars may have debris from terrestrial zoneplanet formation.
