heal.abstract |
We calculate the three-loop function for the Gross-Neveu model, showing explicitly the techniques used to minimize the number of diagrams needed to be evaluated. The lack of a term quadratic in N suggests that an N-independent coupling rescaling could possibly eliminate all but the first two terms of the function. © 1991 The American Physical Society. |
