We determine the ground state and first excited state masses of singly and doubly charmed spin 1/2 and 3/2 baryons with positive and negative parity. Configurations with Nf=2+1 nonperturbatively improved Wilson-clover fermions were employed, with the same quark action also being used for the valence quarks, including the charm. The spectrum is calculated for pion masses in the range Mπ∼259–460  MeV at a lattice spacing a∼0.075  fm. Finite volume effects are studied comparing lattices with two… 
Axial charges of hyperons and charmed baryons using N f = 2 + 1 + 1 twisted mass fermions
The axial couplings of the low lying baryons are evaluated using a total of five ensembles of dynamical twisted mass fermion gauge configurations. The simulations are performed using the Iwasaki
Spectrum of Nonstrange Singly Charmed Baryons in the Constituent Quark Model
We study the masses of radial and orbital excited states of nonstrange singly charmed baryons in the framework of hypercentral Constituent Quark Model (hCQM). To obtain the mass spectra, the Coulomb
Low-energy constants from charmed baryons on QCD lattices
We study the light quark-mass dependence of charmed baryon masses as measured by various QCD lattice collaborations. A global fit to such data based on the chiral SU(3) Lagrangian is reported on. All
Strong Decays of Charmed Baryons in Heavy Hadron Chiral Perturbation Theory: An Update
We first give a brief overview of the charmed baryon spectroscopy and discuss their possible structure and spin-parity assignments in the quark model. With the new Belle measurement of the widths
Masses of $D$ mesons, $D_s$ mesons and charmonium states from twisted mass lattice QCD
We compute masses of D mesons, Ds mesons and charmonium states using Wilson twisted mass lattice QCD. We present results for spin J = 0,1,2,3, parity P = −,+ and in case of charmonium also charge
Excited and exotic charmonium, Ds and D meson spectra for two light quark masses from lattice QCD
A bstractWe present highly-excited charmonium, Ds and D meson spectra from dynamical lattice QCD calculations with light quarks corresponding to Mπ ∼ 240 MeV and compare these to previous results
Mass spectra of mesons containing charm quarks - continuum limit results from twisted mass fermions
We present results from an ongoing computation of masses of $D$ mesons, $D_s$ mesons and charmonium, including both ground states and several parity and angular momentum excitations. We employ 2+1+1
Mass spectra and Regge trajectories of , , and baryons
We calculate the mass spectra of the singly charmed baryons (, , and ) using the hypercentral constituent quark model (hCQM). The hyper color Coulomb plus linear potential is used to calculate the
Continuum limit of the D meson, Ds meson, and charmonium spectrum from Nf=2+1+1 twisted mass lattice QCD
We compute masses of $D$ meson, $D_s$ meson and charmonium states using $N_f=2+1+1$ Wilson twisted mass lattice QCD. All results are extrapolated to physical light quark masses, physical strange and
Study of bottom and charmed baryons in quark-diquark model
In this work, we study the properties of charm- and bottom-flavored baryons in the approximative quark-diquark modelin which the structure of baryons is considered as the bound states of
