The Heavy Quarkonium Spectrum at Order mαs5 αs
N. Brambilla, A. Pineda, J. Soto, A. Vairo
Abstract
We compute the complete leading-log terms of the next-to-next-to-next-to-leading-order corrections to potential NRQCD. As a by-product we obtain the leading logs at O(mαs5) in the heavy quarkonium spectrum. These leading logs, when ΛQCD mαs2, give the complete O(mαs5 αs) corrections to the heavy quarkonium spectrum.
