  "abstract": "We study the possibility that the $\\gamma$-ray loud active galactic nuclei (AGN) are the sources of ultra-high energy cosmic rays (UHECR), through the correlation analysis of their locations and the arrival directions of UHECR. We use the $\\gamma$-ray loud AGN with $d\\le 100 {\\rm Mpc}$ from the second Fermi Large Area Telescope AGN catalog and the UHECR data with $E\\ge 55 {\\rm EeV}$ observed by Pierre Auger Observatory. The distribution of arrival directions expected from the $\\gamma$-ray loud AGN is compared with that of the observed UHECR using the correlational angular distance distribution and the Kolmogorov-Smirnov test. We conclude that the hypothesis that the $\\gamma$-ray loud AGN are the dominant sources of UHECR is disfavored unless there is a large smearing effect due to the intergalactic magnetic fields.",
