We present a Spitzer archival project to search for infrared excess due to debris disks around 67 main-sequence stars for which planets have been found using radial velocity methods. We used MIPS 24 and 70 micron measurements, since the contrast between the emission of the stellar photosphere and the cold dust is highest in the far infrared. Our sample includes all planet-bearing stars for which MIPS measurements are available in the Spitzer archive to date, and thus uses a considerably larger sample than in previously published studies. We compare the results with a sample of 77 field stars without any known planets (published by Beichman et al. 2006). We analyse whether the frequency and magnitude of infrared excess is different for planet-bearing stars and field stars and whether the metallicity distribution of stars with planets and excess is different from that of field stars with excess. In our study we also take advantage of the non-detections by using statistical methods especially developed for datasets with upper limits.
