Low momentum expansion of one loop amplitudes in heterotic string theory
Abstract We consider the low momentum expansion of the four graviton and the two graviton-two gluon amplitudes in heterotic string theory at one loop in ten dimensions, and analyze contributions upto the D2ℛ4 $$ {D}^2{\mathrm{\mathcal{R}}}^4 $$ interaction from the four graviton amplitude, and the D...
