M5brane and Dbrane scattering amplitudes
Abstract
We present treelevel nparticle onshell scattering amplitudes of various brane theories with 16 conserved supercharges. These include the worldvolume theory of a probe D3brane or D5brane in 10D Minkowski spacetime as well as a probe M5brane in 11D Minkowski spacetime, which describes self interactions of an abelian tensor supermultiplet with 6D (2, 0) supersymmetry. Twistorstringlike formulas are proposed for treelevel scattering amplitudes of all multiplicities for each of these theories. The R symmetry of the D3brane theory is shown to be SU(4) × U(1), and the U(1) factor implies that its amplitudes are helicity conserving. Each of 6D theories (D5brane and M5brane) reduces to the D3brane theory by dimensional reduction. As special cases of the general M5brane amplitudes, we present compact formulas for examples involving only the selfdual B field with n = 4, 6, 8.
