Properties of excited B-c states in QCD
Alıyev, Tahmasıb; Barakat, T.; Bilmiş, Selçuk (Elsevier BV, 2019-10-01)
The mass and leptonic decay constants of recently observed two new excited B-c states at LHC are studied within the QCD sum rules. Considering the contributions of the ground and radially excited states, the mass and resid...
N*(1535) -> N transition form-factors due to the axial current
Alıyev, Tahmasıb; Barakat, T.; Simsek, K. (American Physical Society (APS), 2019-09-24)
The form-factors for the transition N* (1535) -> N induced by isovector and isoscalar axial currents within the framework of light cone QCD sum rules by using the most general form of the interpolating current are calculat...
Radiative decays of the p-wave charmed heavy baryons
Alıyev, Tahmasıb; Barakat, T.; Savcı, Mustafa (Springer Science and Business Media LLC, 2019-05-23)
The radiative decays of the p-wave charmed heavy baryons to the ground state baryon states are studied in the framework of the light cone QCD sum rules method. Firstly, the transition form factors that describe these trans...
Determination of the quantum numbers of Sigma(b)(6097)(+/-) via their strong decays
Alıyev, Tahmasıb; Azizi, K.; Sarac, Y.; Sundu, H. (2019-05-08)
Recent experimental progress has led to the detection of many new hadrons. Very recently, the LHCb Collaboration announced the observation of two new Sigma(b)(6097)(+/-) states in the Lambda(0)(b)pi(+/-) invariant mass dis...
Study of the Lambda(b) -> N*l(+)l(-) decay in light cone sum rules
Alıyev, Tahmasıb; Barakat, T.; Savcı, Mustafa (Springer Science and Business Media LLC, 2019-05-03)
The form factors of the bN+- decay are calculated in the framework of the light cone QCD sum rules. In the calculations the contribution of the negative parity b baryon is eliminated by constructing the sum rules for diffe...
The mass and residues of radially and orbitally excited doubly heavy baryons in QCD
Alıyev, Tahmasıb; Bilmiş, Selçuk (Elsevier BV, 2019-04-01)
The mass and residues of the first radial and orbital excitations of J = 1/2 baryons containing two heavy quarks (b or c) are calculated within the QCD sum rules method. In calculations, the general forms of the interpolat...
Radiative decays of the heavy tensor mesons in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2019-01-11)
The transition form factors of the radiative decays of the heavy tensor mesons to heavy pseudoscalar and heavy vector mesons are calculated in the framework of the light-cone QCD sum rules method at the point Q(2) = 0. Usi...
Structure of the Xi(b)(6227)(-) resonance
Alıyev, Tahmasıb; AZİZİ, KAZEM; SARAÇ OYMAK, YASEMİN; SUNDU PAMUK, HAYRİYE (2018-11-16)
We explore the recently observed Xi(b)(6227)(-) resonance to fix its quantum numbers. To this end, we consider various possible scenarios: It can be considered as either a 1P or 2S excitation of the Xi(b) and Xi'(b)(5935) ...
Nature of the Omega (2012) through its strong decays
Alıyev, Tahmasıb; AZİZİ, KAZEM; SARAÇ OYMAK, YASEMİN; SUNDU PAMUK, HAYRİYE (Springer Science and Business Media LLC, 2018-11-03)
We extend our previous analysis on the mass of the recently discovered Omega (2012) state by investigation of its strong decays and calculation of its width employing the method of light cone QCD sum rule. Considering two ...
On the nature Xi(c) (2930)
Alıyev, Tahmasıb; AZİZİ, KAZEM; SUNDU PAMUK, HAYRİYE (Springer Science and Business Media LLC, 2018-09-26)
The single charmed excited Xi(c)(2930) state was discovered many years ago by the BABAR Collaboration and recently confirmed by Belle experiment. However, both these experiments, unfortunately, could not fix the quantum nu...
