Using the most general form of the interpolating current for the octet baryons, the magnetic moments of the negative-parity baryons are calculated within the light-cone sum rules. The contributions coming from diagonal transitions of the positive-parity baryons and also from a nondiagonal transition between positive-and negative-parity baryons are eliminated by considering the combinations of different sum rules corresponding to the different Lorentz structures. A comparison of our results on magnetic moments of the negative- parity baryons with the other approaches existing in the literature is presented.

Electromagnetic form factors of octet baryons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2013-06-10) The electromagnetic form factors of octet baryons are estimated within light cone QCD sum rules method, using the most general form of the interpolating current for baryons. A comparison of our predictions on the magnetic dipole and electric form factors with the results of other approaches is performed.
Magnetic dipole moments of the negative parity J(PC)=2(--) mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2018-04-18) Magnetic dipole moments of the negative parity light and heavy tensor mesons are calculated within the light cone QCD sum rules method. The results are compared with the positive parity counterparts of the corresponding tensor mesons. The results of the analysis show that the magnetic dipole moments of the negative parity light mesons are smaller compared to those of the positive parity mesons. Contrary to the light meson case, magnetic dipole moments of the negative parity heavy mesons are larger than the ...
Magnetic moment of the rho meson in QCD light cone sum rules Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2003-09-01) The magnetic moment mu of the rho meson is studied in QCD light cone sum rules, and it is found that mu=(2.3+/-0.5), in units of e/2m(rho). A comparison of our result on the magnetic moment of the rho meson with the predictions of the other approaches is presented.
Magnetic moments of Delta baryons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-10-23) We calculate the magnetic moments of Delta baryons within the framework of QCD sum rules. A comparison of our results on the magnetic moments of the Delta baryons with the predictions of different approaches is presented.
Magnetic moment for the negative parity Lambda -> Sigma(0) transition in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (2016-07-10) The magnetic moment of the Lambda -> E transition between negative parity baryons is calculated in framework of the QCD sum rules approach by using the general form of the interpolating currents. The pollution arising from the positive-to-positive, and positive-to-negative parity baryons is eliminated by constructing the sum rules for different Lorentz structures. A comparison of our result with the predictions of the results of other approaches for the positive parity baryons is presented. (C) 2016 Publish...
