The resulting CHY formula gives rise to the Parke-Taylor formula for all n, which is difficult to get in the original CHY momentum-polarization representation. A complication encountered in trying to derive the BCFW factorization in the spinor representation will also be discussed. | | Contact person 所内联系人 | Song He | |
