v5 v6 15 15 We suggest to proceeed in steps. 16 16 17 === First Step : getting a code for pp>X + n gluons exact at all 1/Nc^n^and compiling. ===17 === First Step : getting a code for pp>X + n gluons exact at all orders in 1/Nc and compiling. === 18 18 19 19 This should be achieved rather easily, if we don't worry about SPEED (which we will in the next step, of course). 20 Anyway is mandatory to have a code that can do |M|^2^ EXACTLY (at all orders in 1/Nc ^n^). Note that the current20 Anyway is mandatory to have a code that can do |M|^2^ EXACTLY (at all orders in 1/Nc). Note that the current 21 21 algorithm that gets the color matrix is already able to select powers in 1/Nc so this is not an issue. 22 22 … … 35 35 and getting all the others by applying the same permutations. Finally, if one is able to generate the permutations instead of listing them in the code, one could really write a small code. 36 36 37 === Third Step : Expand the results in powers and MC over flows 1/Nc^2===37 === Third Step : Expand the results in powers of 1/Nc and MC over color flows === 38 38 39 39 More about this to come...
