Ωcγ → Ω∗ transition in lattice QCD
(Elsevier, 2015-07-30)
We study the electromagnetic View the MathML sourceΩcγ→Ωc⁎ transition in 2+12+1 flavor lattice QCD, which gives access to the dominant decay mode of View the MathML sourceΩc⁎ baryon. The magnetic dipole and the electric ...
A look inside charmed-strange baryons from lattice QCD
(American Physical Society, 2015-12-01)
The electromagnetic form factors of the spin-3/2 Ω baryons, namely Ω, Ω∗c, Ω∗cc and Ωccc, are calculated in full QCD on 323×64 PACS-CS lattices with a pion mass of 156(9) MeV. The electric charge radii and magnetic moments ...
QCD coupling constants and VDM
(AIP, 2012)
QCD sum rules for coupling constants of vector mesons with baryons are constructed.The corresponding QCD sum rules for electric charges and magnetic moments are also derived and with the use of vector-meson-dominance model ...
First lattice calculation of charmed hadrons' electromagnetic form factors
(IOP Publishing, 2014)
Electromagnetic form factors of D and D* mesons and Ξcc, Σc, Ωc and Ωcc baryons are calculated in 2+1 flavor lattice QCD. As a by product of this calculation electric/magnetic charge radii and magnetic moments are extracted. ...
Theoretical determination of K(1)(1270,1400) mixing angle in QCD
(IOP Publishing, 2012)
In quark model, the strange axial vector mesons K1(1270) and K1(1400) are defined as the mixtures of orbital angular momentum states K1A and K1B. In this work, by using the orthogonality of the mass eigenstates, we have ...
ΛcΣcπ coupling and Σc → Λcπ decay in lattice QCD
(Elsevier, 2017-05-10)
We evaluate the Lambda(c)Sigma(c)pi coupling constant (G(Lambda c)Sigma(c)pi) and the width of the strong decay Sigma(c) -> Lambda(c)pi in 2 + 1flavor lattice QCD on four different ensembles with pion masses ranging from ...
Vector and axial-vector couplings of D and D⁎ mesons in 2+1 flavor lattice QCD
(Elsevier, 2013-02-12)
Using the axial-vector coupling and the electromagnetic form factors of the D and D⁎ mesons in 2+1 flavor lattice QCD, we compute the D⁎Dπ , DDρ and D⁎D⁎ρ coupling constants, which play an important role in describing ...
Electromagnetic structure of charmed baryons - extended to spin-3/2
(2015)
The electromagnetic form factors of the spin-3/2 Ω baryons, namely the Ω, Ω∗c , Ω∗ cc and Ωccc, are calculated in full QCD on 323 x 64 PACS-CS lattices with a pION mass of 156(9) MeV. The electric charge radii and magnetic ...
Ξcγ→Ξc ′ transition in lattice QCD
(Elsevier, 2017-09-10)
We evaluate the electromagnetic Ξcγ→Ξc ′ transition on 2+1 flavor lattices corresponding to a pion mass of ∼156 MeV. We extract the magnetic Sachs and Pauli form factors which give the Ξc–Ξc ′ transition magnetic moment ...
Electromagnetic structure of charmed baryons
(Proceedings of Science, 2013)
We compute the electromagnetic form factors of charmed baryons (∑ c, (ξcc, ω c and ω cc) in 2+1 Lattice QCD and extract their electric and magnetic charge radii as well as their magnetic mo-ments. Such observables are ...
