The effects of charmonium on the properties of the 1++ hidden charm poles in effective field theory
Cincioglu, E.; Özpineci, Altuğ; Yildirim Yilmaz, D. (2021-10-01)
© 2021 Elsevier B.V.In this study, the properties of the JPC=1++ hidden charm poles are analyzed under the variation of the bare 2P charmonium mass within the effective field theory proposed in Ref. [1]. The main focus of ...
On the calculation of covariant expressions for Dirac bilinears
Olpak, M. A.; Özpineci, Altuğ (2021-09-01)
In this article, various approaches to calculate covariant expressions for the bilinears of Dirac spinors are presented. For this purpose, algebraic equations defining Dirac spinors are discussed. Following that, a covaria...

B -> T transition form factors in light-cone sum rules
Aliev, T. M.; Dag, H.; Kokulu, A.; Özpineci, Altuğ (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 = D-2*, K-2*, a(2), f(2) (J(P) = 2(+)). We employ the QCD light...
Radiative decay of the X(3872) as a mixed molecule-charmonium state in effective field theory
Cincioglu, E.; Özpineci, Altuğ (Elsevier BV, 2019-10-10)
Assuming that X(3872) is a mixture between 2P charmonium and (D) over barD* molecular states with J(PC) = 1(++), an analysis of X(3872) radiative decays into J/psi gamma and psi(2S)gamma is presented. The modification of t...
X(3872) and its heavy quark spin symmetry partners in QCD sum rules
Mutuk, Halil; Sarac, Yasemin; Gumus, Hasan; Özpineci, Altuğ (Springer Science and Business Media LLC, 2018-11-08)
X(3872) presents many surprises after its discovery more than ten years ago. Understanding its properties is crucial to understand the spectrum of possible exotic mesons. In this work, X(3872) meson and its heavy quark spi...
Light cone distribution amplitudes of excited p-wave heavy quarkonia at leading twist
Olpak, M. A.; Özpineci, Altuğ; Tanriverdi, V. (American Physical Society (APS), 2017-07-26)
Leading twist light cone distribution amplitudes (LCDAs) are key ingredients in calculating various hadronic amplitudes using light cone QCD sum rules. This work concentrates on calculating the leading twist LCDAs of p-wav...

Axial vector transition form factors of N -> Delta in QCD
Küçükarslan, Ayşe; Özdem, Ulaş; Özpineci, Altuğ (Elsevier BV, 2016-12)
The isovector axial vector form factors of N -> Delta transition are calculated by employing Light-cone QCD sum rules. The analytical results are analyzedby both the conventional method, and also by a Monte Carlo based app...
Tensor form factors of the octet hyperons in QCD
Küçükarslan, Ayşe; Özdem, Ulaş; Özpineci, Altuğ (American Physical Society (APS), 2016-11-11)
Light-cone QCD sum rules to leading order in QCD are used to investigate the tensor form factors of the Sigma-Sigma,Xi-Xi, and Sigma-Lambda transitions in the range 1 GeV2 <= Q(2) <= 10 GeV2. The DAs of Sigma,Xi, and. bary...
