The magnetic moments of the low lying, negative parity, spin-3/2 baryons, including the Lambda* baryon, are calculated within the light cone QCD sum rules method. The contributions coming from the positive parity, spin -3/2 baryons, as well as from the positive and negative parity spin -1/2 baryons are eliminated by constructing combinations of various invariant amplitudes corresponding to the coefficients of the different Lorentz structures. We also present the results for the magnetic moments of the positive parity, spin -3/2 baryons.

Sigma(Q)Lambda(Q) transition magnetic moments in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2002-05-01) Using the general form of Sigma(Q) and Lambda(Q) (Q=b or c) currents, Sigma(Q)Lambda(Q) transition magnetic moments are calculated in the framework of the light cone QCD sum rules method. In this approach nonperturbative effects are described by the photon wave functions and only two-particle photon wave functions are taken into account. Our predictions of the transition magnetic moments are mu(Sigmac)Lambda(c)=-(1.5+/-0.4)mu(N) and mu(Sigmab)Lambda(b)=-(1.6+/-0.4)mu(N). A comparison of our results with the...
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 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 Moments of 70-Plet Baryons in Quark Model and QCD Sum Rules Alıyev, Tahmasıb (2015-01-01) Magnetic moments of the positive parity 70-plet baryons are estimated in the framework of the nonrelativistic quark model and QCD sum rules method. It is found that the magnetic moments of the 70-plet baryons can be expressed in terms of the F and D couplings and exhibit unitary symmetry. The QCD sum rules for the magnetic moments of the 70-plet octet baryons are formulated. A comparison of our results on magnetic moments of 56-plet and 70-plet baryons predicted from QCD sum rules is presented.
Diagonal and transition magnetic moments of negative parity heavy baryons in QCD sum rules Alıyev, Tahmasıb; Barakat, T.; Savcı, Mustafa (2015-08-06) Diagonal and transition magnetic moments of the negative parity, spin-1/2 heavy baryons are studied in the framework of the light cone QCD sum rules. By constructing the sum rules for different Lorentz structures, the unwanted contributions coming from negative-to-positive (positive-to-negative) parity transitions are removed. It is obtained that the magnetic moments of all baryons, except Lambda(0)(b), Sigma(+)(c), and Xi(c)'(+), are quite large. It is also found that the transition magnetic moments betwee...
