Higher-order condensate corrections to ϒ masses, leptonic decay rates and sum rules

Higher-order condensate corrections to ϒ masses, leptonic decay rates and sum rules

Abstract With the recent completion of NNNLO results, the perturbative description of the ϒ system has reached a very high level of sophistication. We consider the non-perturbative corrections as an expansion in terms of local condensates, following the approach pioneered by Voloshin and Leutwyler....
