Electromagnetic structure of charmed baryons in Lattice QCD
(Springer Science+Business Media, 2014-05)
As a continuation of our recent work on the electromagnetic properties of the doubly charmed (sic)(cc) baryon, we compute the charge radii and the magnetic moments of the singly charmed Sigma(c), Omega(c) and the doubly ...
Radiative transitions of doubly charmed baryons in lattice QCD
(American Physical Society, 2018-12-13)
We evaluate the spin-3/2→spin-1/2 electromagnetic transitions of the doubly charmed baryons on 2+1 flavor, 323×64 PACS-CS lattices with a pion mass of 156(9) MeV/c2. A relativistic heavy quark action is employed to minimize ...
Pseudoscalar-meson octet-baryon coupling constants from two-flavor lattice QCD
(Elsevier, 2010-04-01)
We evaluate the pseudoscalar-meson octet-baryon coupling constants and the corresponding axial charges in eight channels (πNN, πΣΣ, πΛΣ, KΛN, KΣN, πΞΞ, KΛΞ and KΣΞ) in lattice QCD with two flavors of dynamical quarks. The ...
Pseudoscalar-meson-octet-baryon coupling constants in two-flavor lattice QCD
(American Physical Society, 2009-04-01)
We evaluate the πΝΝ, π∑∑, πΛ∑, KΛN and K∑N coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters representing the SU(3)-flavor symmetry are computed ...
Axial charges of octet baryons in two-flavor lattice QCD
(Elsevier, 2010-03-15)
We evaluate the strangeness-conserving NN, ΣΣ, ΞΞ, ΛΣ and the strangeness-changing ΛN, ΣN, ΛΞ, ΣΞ axial charges in lattice QCD with two flavors of dynamical quarks and extend our previous work on pseudoscalar-meson–octet-baryon ...
Isovector axial-vector form factors of octet baryons in QCD
(American Physical Society, 2011-06-01)
We compute the diagonal isovector axial-vector as well as induced pseudoscalar form factors of nucleon, Σ, and ≡ baryons by employing the light-cone QCD sum rules to leading order in QCD and including distribution amplitudes ...
Tensor form factors of nucleon in QCD
(Elsevier, 2011-10-25)
We extract the isovector tensor nucleon form factors, which play an important role in understanding the transverse spin structure of the nucleon when related to the quark helicity-flip generalized parton distributions via ...
QCD sum rules for the coupling constants of vector mesons to octet baryons
(Springer Science+Business Media, 2013-05)
The QCD sum rules on the light cone proposed by Wang for the coupling constants of the ρ meson are generalized to the vector mesons ω and φ and all octet baryons, the Λ-hyperon included. A comparison with other results is given.
Meson-baryon coupling constants in two-flavor lattice QCD
(American Institute of Physics, 2010)
We evaluate the pseudoscalar-meson coupling constants and the strangeness-conservingand the strangeness-changing axial charges of octet baryons in lattice QCD with two flavors ofdynamical quarks.We find that the coupling ...
Electromagnetic structure of charmed hadrons
(IOP Publishing, 2014)
We compute the electromagnetic structures of D and D* mesons, the singly charmed Σc, Ωc and the doubly charmed Ξcc, Ωcc baryons in 2+1 flavor Lattice QCD. We extract the charge radii and the magnetic moments of these ...
