In order for this CHY formalism to describe the complete Yang-Mills theory, a similar formula must be found for off-shell gluons, namely, all tree-level Green's functions in momentum space. This is a non-trivial task because space-time local interaction and its propagation, as well as local gauge invariance demanded by the Yang-Mills theory, must be directly incorporated into a Mobius-invariant integral of momenta and polarization. I will discuss how this can be done. | | Contact Person 所内联系人 | Song He | |
