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 ...
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 ...
B → T transition form factors in light-cone sum rules
(American Physical Society, 2019-11-11)
We present a new calculation of the semileptonic tree-level and flavor-changing neutral current form
factors describing B-meson transitions to tensor mesons T ¼ D2, K2, a2, f2 (JP ¼ 2þ). We employ the QCD light-cone sum ...
