Ξc → Ξ semileptonic decays: A light cone sum rules view on the experiment-lattice tension Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2026-01-09) We present a light-cone QCD sum rule (LCSR) analysis of the semileptonic decays of Ξc baryons, focusing on the channels Ξ0c → Ξ−lþνl, and Ξþc → Ξ0lþνl. The transition form factors are calculated within the light-cone quant...
Semileptonic Λc→Λℓνℓ decays in light-cone QCD sum rules with Λc distribution amplitudes Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2026-01-01) We study the semileptonic decay of its SU(3) partner, the Λc→Λℓ+νℓ (ℓ=e,μ) transition, within the framework of light-cone QCD sum rules (LCSR) by using the distribution amplitudes of heavy Λc baryon. The numerical analysis...
Explaining Belle data on B→K(*)vv decays via dark Z resonances Alıyev, Tahmasıb; Elpe, A.; SELBUZ, LEVENT; Turan, I. (2025-07-01) The Belle II Collaboration reported the first measurement on Br(B+-* K+vv), which lies 2.76 away from the Standard Model expectation. This result may be manifestation of new physics beyond the Standard Model. In present wo...
Analysis of the B(s) → T(JP=2-) transition in light cone QCD sum rules Alıyev, Tahmasıb; Sarac, Y. (2025-03-01) The semileptonic B(s) → T(JP=2-)l+l- decays induced by flavor changing neural currents are investigated within the light cone quantum chromodynamics (QCD) sum rule method in the leading order of O(αs). We apply the B meson...
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...
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...
