Let $n\geq 5$ and consider stringy on-shell Ward identities associated with the $SL(K+3,\mathbb{C})$ symmetry. The nonlinear Ward identities are obtained through the reduction of s…

Let $t^j_\ell$ be parameters interpolating between the twistor-string integrand at $t^j_\ell=1$ and the BCFW expansion at $t^j_\ell=0$. Parameter-independence conjecture. The resul…
