I and some classmates are recently teaching ourselves the famous book Foundations of Perturbative QCD by John Collins via a form of regular peer reading group. We find that exercises in this book are really worth working on. But, as a group of relatively junior students, we are hesitating to go deeper before finding a way to verify our answers. One obvious solution must be to consult some more senior researchers. But, other than that we want to know whether there exists a document of solutions to this book, so that at least we can self-verify even if we fail to find such a senior mentor.
