Sorry, I don't have access to an English edition of G&S, but, in my previous answer, I gave an explicit reference for the formulas and the appendix to the Russian edition where they can be found. | |
| May 22, 2013 at 9:48 | comment | added | Anirbit | @Igor Khavkine You know of a reference with Feynman parameters with 3 factors as here? Its hard to find such examples in text-books. (..also looking at the 1964 Gelfand-Shillof edition I couldn't locate the identities you used the last time..) | |
| May 21, 2013 at 12:03 | comment | added | Igor Khavkine | The obvious generalization does not work, since this is no longer a pure convolution integral. In the standard literature, such integrals are handled using Feynman or Schwinger parameters. Have you tried to work those out yourself? | |
