Charmonium content of χc1(3872) in light-cone sum rules at twist 3 AKAN, TARIK; Olpak, Mehmet Ali; Özpineci, Altuğ (2025-10-01) In this study, we utilize light-cone QCD sum rules at twist-3 accuracy to compute the coupling parameters of the chi c1(2P) state with D and D* mesons. The analysis reveals that the observed chi c1(3872) meson incorporates...
Reanalysis of rare radiative Ξb- → Ξ-γ decay in QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Sarac, Y. (2024-03-01) The upper limit of the branching ratio of the rare Ξb-→Ξ-γ decay is obtained as BR(Ξb-→Ξ-γ)<1.3×10-4 by the LHCb. In the present work we study this decay within the light cone QCD sum rules employing the Ξb distribution am...
FCNC decays of spin-1/2 double heavy baryons to spin-3/2 single heavy baryons Alıyev, Tahmasıb; Aşkan, Emre; Özpineci, Altuğ; SARAÇ OYMAK, YASEMİN (2024-01-01) In recent years, there have been many discoveries in the spectroscopy of hadrons containing heavy quarks. Almost all baryons containing a single heavy quark are discovered in experiments. The quark model predicts the exist...
Radiative decays of the spin- 3/2 to spin- 1/2 doubly heavy baryons in QCD Alıyev, Tahmasıb; Aşkan, Emre; Özpineci, Altuğ (2023-09-01) The spin-3/2 to spin-1/2 doubly heavy baryon transition magnetic dipole GM and electric quadrupole GE form factors are calculated in the framework of the light cone sum rules method. Moreover, the decay widths of correspon...
Semileptonic Bc decays to P-wave charmonia in the light-cone QCDSR AKAN, TARIK; Cincioglu, Elif; Özpineci, Altuğ; TEĞMEN, ADNAN (2023-06-01) Bc mesons are laboratories for probing heavy quark physics. Furthermore, they decay into charmonia and hence their decays can be used to analyze possible exotic charmonium. In this work, the semileptonic decays of Bc meson...
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) 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 the current work is ...
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...
Teorik Parçacık Fizikçisi Gözüyle Açık Veri Özpineci, Altuğ (2021-05-26)
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...
