Heavy chi(Q) (2) tensor mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2010-06-14) The masses and decay constants of the ground state heavy chi(Q2) (Q = b, c) tensor mesons are calculated in the framework of the QCD sum rules approach. The obtained results on the masses are in good consistency with the experimental values. Our predictions on the decay constants can be verified in the future experiments.
Strong Coupling Constants of Negative Parity Heavy Baryons with pi and K Mesons Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2017-01-01) The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light pi and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-sextet, sextet-antitriplet, and antitriplet-antitriplet transitions can be described by only one corresponding function. The pollution arising from the positive to positive, positive to negative, and negative to positive parity baryons transitions is eliminated by...
Vector meson dominance and radiative decays of heavy spin-3/2 baryons to heavy spin-1/2 baryons Alıyev, Tahmasıb; Savcı, Mustafa (2012-04-10) Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light vector mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.
Magnetic dipole moment of the light tensor mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2010-07-01) The magnetic dipole moments of the light tensor mesons f(2), a(2) and the strange K-2*(0)(1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f(2) and a(2) tensor mesons, while it has a small nonzero value for the neutral strange K-2*(0)(1430) tensor meson.
Vector meson-baryon strong coupling constants in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (American Physical Society (APS), 2009-07-01) Using the most general form of the interpolating current of the baryons, the strong coupling constants of the light vector mesons with the octet baryons are calculated within the light cone QCD sum rules. The SU(3)(f) symmetry breaking effects are taken into account in the calculations. It is shown that each of the electric and magnetic coupling constants can be described in terms of three universal functions. A detailed comparison of the results of this work on aforementioned couplings with the existing th...
