Radiative correction of the correlator for (0++,1-+) light hybrid
H. Y. Jin, J. G. Körner
Abstract
We calculate the radiative corrections to the current-current correlator of the hybrid current g q(x)γνiGμνaTaq(x). Based on this new result we use the QCD sum rule approach to estimate lower bounds on the masses of the JPC=1-+ and 0++ light hybrids.
