B → T transition form factors in lightcone sum rules
Aliev, T. M.; Dağ, Hüseyin; Kokulu, A.; Ozpineci, A. (American Physical Society, 20191111)We present a new calculation of the semileptonic treelevel and flavorchanging neutral current form factors describing Bmeson transitions to tensor mesons T ¼ D2, K2, a2, f2 (JP ¼ 2þ). We employ the QCD lightcone sum ... 
Electromagnetic structure of charmed hadrons
Erkol, Güray; Can, K. U.; Işıldak, Bora; Oka, M.; Ozpineci, A.; Takahashi, T. T. (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 ... 
Isovector axialvector form factors of octet baryons in QCD
Erkol, Güray; Ozpineci, A. (American Physical Society, 20110601)We compute the diagonal isovector axialvector as well as induced pseudoscalar form factors of nucleon, Σ, and ≡ baryons by employing the lightcone QCD sum rules to leading order in QCD and including distribution amplitudes ... 
QCD coupling constants and VDM
Erkol, Güray; Ozpineci, A.; Zamiralov, V. S. (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 vectormesondominance model ... 
QCD sum rules for the coupling constants of vector mesons to octet baryons
Zamiralov, V. S.; Ozpineci, A.; Erkol, Güray (Springer Science+Business Media, 201305)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 Λhyperon included. A comparison with other results is given. 
Tensor form factors of nucleon in QCD
Erkol, Güray; Ozpineci, A. (Elsevier, 20111025)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 helicityflip 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 axialvector 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, 20130212)Using the axialvector 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 ...
