We study four point loop amplitudes at an arbitrary point in the Coulomb
branch of N=4 super-Yang-Mills theory. We study two particle
unitary cuts up to four loop order. We explicitly verify that bubble and
triangle graphs do not contribute at one loop level and show that the results
hold at higher loop level as well. We also write down an all loop recursion
relation for two particle reducible graphs for four point amplitudes.Comment: Two references are added. One footnote is added in the discussion
