The symbol and alphabet of two-loop NMHV amplitudes from Q ¯ $$ \overline{Q} $$ equations
Abstract We study the symbol and the alphabet for two-loop NMHV amplitudes in planar N $$ \mathcal{N} $$ = 4 super-Yang-Mills from the Q ¯ $$ \overline{Q} $$ equations, which provide a first-principle method for computing multi-loop amplitudes. Starting from one-loop N2MHV ratio functions, we explai...
