Abstract:

Radiative transitions among heavy quarkonium systems are investigated in a general framework of the boosted LS-coupling (BLS) scheme, where mesons are treated in a manifestly covariant way and conserved effective currents are explicitly given. As a result it is shown that our theory reproduces the qualitative features of experiments remarkably well, giving evidence for the validity of the BLS scheme.
