Abstract :
We consider the embedding method of the superconformal group in four dimensions in the case of extended supersymmetry, hence generalizing the recent work of Goldberger, Skiba and Son which was restricted at image. Moreover, we work out explicitly the case of image chiral superfields in four dimensions, putting the component fields in correspondence with Pascalʼs pyramid at layer image. This correspondence is a generic property of the image-extended chiral sector.
