Spectroscopy of triply-charmed baryons from lattice QCD

Excited-state spectroscopy of singly, doubly and triply-charmed baryons from lattice QCD

We present the ground and excited state spectra of singly, doubly and triply-charmed baryons by using dynamical lattice QCD. A large set of baryonic operators that respect the symmetries of the lattice and are obtained after subduction from their continuum analogues are utilized. These operators transform as irreducible representations of SU(3)F symmetry for flavour, SU(4) symmetry for Dirac sp...

Baryon Masses in Lattice QCD with Exact Chiral Symmetry

We investigate the baryon mass spectrum in quenched lattice QCD with exact chiral symmetry. For 100 gauge configurations generated with Wilson gauge action at β = 6.1 on the 20×40 lattice, we compute (point-to-point) quark propagators for 30 quark masses in the range 67 MeV ≤ mq ≤ 1790 MeV. For baryons only composed of strange and charm quarks, their masses are extracted directly from the time ...

Charmed Baryon Spectroscopy from lattice QCD for N f = 2 + 1 flavours

Constituent-quark model description of triply heavy-baryon nonperturbative lattice QCD data

This paper provides results for the spectra of triply charmed and bottom baryons based on a constituent quark model approach. We take advantage of the assumption that potential models are expected to describe triply heavy baryons to a similar degree of accuracy as the successful results obtained in the charmonium and bottomonium sectors. The high precision calculation of the ground state and po...

We present results for masses of spin-1/2 and spin-3/2 double-charm baryons in quenched lattice QCD, from an exploratory study using a non-perturbatively improved clover action at β = 6.2. We have studied local operators and we observe, after appropriate projections, a good signal for the ground states. We also present results for single-charmed baryons and spin-splittings for both double-and s...
