Why quarkonium hybrid coupling to two S-wave heavy-light mesons is not suppressed
R. Bruschini
We examine the couplings of quarkonium hybrids to heavy-light meson pairs in the Born-Oppenheimer approximation for QCD. The lowest hybrid multiplets consist of bound states of the…

Heavy-Quark spin symmetry breaking in the Born-Oppenheimer approximation
R. Bruschini
Heavy-quark spin symmetry is explicitly broken by the mass splitting between a heavy-light pseudoscalar meson and its vector partner. This fact plays a pivotal role in the physics…
