Mixing angle between P1 3 and P1 1 states in heavy axial vector mesons within the QCD sum rules framework Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2025-01-01) In this study, we calculate the mixing angles between the axial-vector mesons D1(s1)-D1(s1)′ and B1(s1)-B1(s1)′ using the QCD sum rules approach. Our results are θ1=28.2±0.6°, θ2=26.6±0.6°, θ3=38.6±0.1°, and θ4=38.5±0.1°. ...
Determination of the multipole moments of the JP=3- mesons via QCD sum rules Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2024-12-01) The multipole moments of the JP=3- tensor mesons are obtained using light-cone sum rules. Our results are compared with the predictions of the light-cone helicity formalism within the framework of SU(3) flavor symmetry. We...
Analysis of strong decays of SU(3) partners of Ω(2012) baryon Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2024-08-01) We estimate the coupling constants and decay widths of the SU(3) partners of the Omega(2012) hyperon, as discovered by the BELLE Collaboration, using the distribution amplitudes of the octet baryons within the light cone s...
QCD sum rule study of JP = 1± exotic states with two heavy quarks in the molecular picture Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, M. (2024-06-01) In this study, the spectroscopic parameters of exotic molecular states composed of mesons containing two heavy quarks (scalar - axial and pseudoscalar - axial meson combinations) are investigated within the QCD sum rules. ...
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...
The study of weak decays induced by [Formula presented] transition in light-cone sum rules Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2023-12-10) In this study, we analyzed the weak decays induced by [Formula presented] transitions within the light-cone sum rules. Specifically, semileptonic decays of the bottom baryons into the P-wave baryons Λb→Λc(2625)ℓνl and Ξb→Ξ...
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...
Constraining nonminimal dark sector scenarios with the COHERENT neutrino scattering data Elpe, Altuğ; Akyumuk, E.; Alıyev, Tahmasıb; SELBUZ, LEVENT; Turan, İsmail (2023-04-01) Abelian dark sector scenarios embedded into the two-Higgs doublet model are scrutinized within the coherent elastic neutrino-nucleus scattering experiment, which was first measured by the COHERENT Collaboration in 2017 wit...
Looking for heavy axial tensor mesons via their strong decays in light cone QCD Alıyev, Tahmasıb; Bilmiş, Selçuk; Çiftci, Ruken Asya; Savcı, Mustafa (2023-03-15) In this study, the strong coupling constants of the unobserved heavy axial tensor mesons to the heavy vector and pseudoscalar π and K mesons, D2D∗π, Ds2D∗K, B2B∗π, Bs2B∗K as well as a heavy axial tensor to axial vector and...
Weak Xi (QQ) -> Sigma(Q)l(+)l(-) decays induced by FCNC in QCD Alıyev, Tahmasıb; Savcı, Mustafa; Bilmiş, Selçuk (2022-10-01) With the discovery of the doubly heavy Xi(cc) baryon, comprehensive studies of the properties of the doubly heavy baryons are started. In the present work, we examine the Xi(bb) -> Sigma(b)l(+)l(-) and Xi(cc) -> Sigma(c)l(...
