D=10 supersymmetric Yang-Mills theory at alpha'⁴

الأصل · EN

The α'² deformation of D=10 SYM is the natural generalisation of the F⁴ term in the abelian Born-Infeld theory. It is shown that this deformation can be extended to α'⁴ in a way which is consistent with supersymmetry. The latter requires the presence of higher-derivative and commutator terms as well as the symmetrised trace of the Born-Infeld α'⁴ term.
