Abstract

Abstract A class of general finite-energy sum rules not necessarily derived from analyticity and crossing property of the amplitude is discussed. An example is given of a sum rule which has over the continuous-moment sum rules the advantages of a more equilibrated participation of low-energy data and a better separation of two nearby Regge-pole contributions.
