Abstract Supersymmetry allows a D 4 R 4 interaction in M-theory. but such an interaction is inconsistent with string theory dualities and so is known to be absent. We provide a novel proof of the absence of the D 4 R 4 M-theory interaction by calculating 4-point scattering amplitudes of 11d supergravitons from ABJM theory. This calculation extends a previous calculation performed to t... https://allfixelectricales.shop/product-category/rangehood-vent-adaptor/
