ON CHIRAL AND NONCHIRAL 1D SUPERMULTIPLETS

摘要

In this talk I discuss and clarify some issues concerning chiral and nonchiral properties of the one-dimensional supermultiplets of the -Extended Supersymmetry. Quaternionic chirality can be defined for = 4, 5, 6, 7, 8. Octonionic chirality for = 8 and beyond. Inequivalent chiralities only arise when considering several copies of = 4 or = 8 supermultiplets.
