Charmonium spectroscopy and mixing with light quark and open charm states from nF=2 lattice QCD

Gunnar S. Bali, Sara Collins, Christian Ehmann

We study the charmonium spectrum including higher spin and gluonic excitations. We determine an upper limit on the mixing of the eta_c ground state with light pseudoscalar flavour-…

Mixing of S-Wave Charmonia with Molecule States

Gunnar Bali, Christian Ehmann

Charmonium states can decay into pairs of and mesons if their masses are above the allowed decay thresholds. In general states near threshold will als…

--mixing with improved stochastic estimators

Christian Ehmann, Gunnar Bali

Charmonia are flavour singlet mesons and thus in principle contributions from disconnected quark line diagrams might affect their masses, either directly or via mixing with other f…

Charmonium spectrum including higher spin and exotic states

Christian Ehmann, Gunnar Bali

We study the charmonium spectrum including higher spin and exotic states. We use the Sheikholeslami-Wilson (clover) action for sea quarks as well as for the charm valence q…

Couplings of hybrid operators to ground and excited states of bottomonia

Tommy Burch, Christian Ehmann

We analyze the overlap of local color-octet meson operators with the and the and their low-lying excited states, especially the first radial excitations. Our analysis is…

Investigation of the overlap of excited bottomonium states with hybrid operators

C. Ehmann, T. Burch, A. Schaefer

We analyze the overlap of color-octet meson operators with the and the and their excited states, especially the first radial excitations. Our analysis is based on NRQCD a…
