Extended Supersymmetry and Extended Supergravity Theories

摘要: The failure of quantized gravity in interaction with matter fields (whether scalar, spinor vector fields) to provide renormalizable results even at the one loop level [1] has led a situation analoguous puzzle V-A theory weak interactions before advent gauge theories. was known be correct tree approximation, but having coupling constant whose dimension inverse mass squared (GF = 1. 01 10−5GeV−2) it giving divergent and non answers level. In similar fashion, classical general relativity is describe accurately, quantum leads results, except case for pure [l]. analogy stronger if remarks that also \(\left( {K \sim \,\left( {{G_N}} \right)\frac{1}{2}\, \,.8\,{{10}^{ - 19}}\,Ge{V^{ 1}}} \right)\). One can think trouble due perturbative approach rather than itself. other possibility look alternative theories which would free divergences.
