A SUM RULES CALCULATION IN THE LIGHT-CONE REPRESENTATION

摘要

In the light-cone representation, vacuum effects are correctly introduced intothe dynamics by the inclusion of induced operators. Recently, some of the induced operators in QCD have been derived. The knowledge of these operators makes it possible to perform calculations of the propertied of QCD resonances using essentially the QCD sum rules approach; but with the inclusion of the induced operators providing the nonperturbative physics rather than the operator product expansion that is used in the standard sum rules approach.
