Tensor form factors of nucleon in QCD
Erkol, Güray; Ozpineci, A. (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 ... -
Theoretical determination of K(1)(1270,1400) mixing angle in QCD
Dağ, Hüseyin; Ozpineci, A.; Çağıl, A.; Erkol, Güray (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 ... -
Vector and axial-vector couplings of D and D⁎ mesons in 2+1 flavor lattice QCD
Can, Kadir Utku; Erkol, Güray; Oka, M.; Ozpineci, A.; Takahashi, T. T. (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 ... -
ΛcΣcπ coupling and Σc → Λcπ decay in lattice QCD
Can, K. U.; Erkol, Güray; Oka, M.; Takahashi, T. T. (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 ... -
Ξcγ→Ξc ′ transition in lattice QCD
Bahtiyar, H.; Can, K. U.; Erkol, Güray; Oka, M.; Takahashi, T. T. (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 ... -
Ωcγ → Ω∗ transition in lattice QCD
Bahtiyar, H.; Can, K. U.; Erkol, Güray; Oka, M. (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 ...
