QCD spin effects in the heavy hybrid potentials and spectra

14 Feb 2020 Brambilla Nora Lai Wai Kin Segovia Jorge Castellà Jaume Tarrús

The spin-dependent operators for heavy quarkonium hybrids have been recently obtained in a nonrelativistic effective field theory approach up to next-to-leading order in the heavy-quark mass expansion. In the effective field theory for hybrids several operators not found in standard quarkonia appear, including an operator suppressed by only one power of the heavy-quark mass... (read more)
