Charmed baryons in lattice QCD
Masses of singly and doubly charmed baryons are calculated in quenched lattice QCD using an improved action of the D234 type on an anisotropic lattice. The mass differences between spin 3/2 and spin 1/2 baryon states are calculated and compared to mass differences between vector and pseudoscalar mesons. The suppression of spin splittings in mesons containing heavy quarks, characteristic of quen...

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...
متن کاملBaryon 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 ...

متن کاملHeavy Quark – Light Diquark Approach to a Heavy Baryon in the Heavy Quark Symmetry Limit
. Abstract— The masses and distance configurations of the ground and excited states of heavy – charmed and bottom baryons J =1/2 ,3/2,containing a single heavy quark and a light diquark are studied within HQS limit of the HQLD sector of NRQCD framework. We find how the average distances between the heavy quark and the center of mass of the light diquark are smaller than the size of the light di...
