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 between neutral negative parity heavy Xi('0)(Q) and Xi(0)(Q) baryons are very small. Magnetic moments of the Sigma(Q) -> Lambda(Q) and Xi(Q)'(+/-) -> Xi(+/-)(Q) transitions are quite large and may be measured in further experiments.

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 J(P)=3/2-baryons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2014-12-29)
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 posit...
Radiative decays of the heavy flavored baryons in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ (2009-03-01)
The transition magnetic dipole and electric quadrupole moments of the radiative decays of the sextet heavy flavored spin 3/2 to the heavy spin 1/2 baryons are calculated within the light cone QCD sum rules approach. Using the obtained results, the decay rate for these transitions are also computed and compared with the existing predictions of the other approaches.
Magnetic moments of Lambda(b) and Lambda(c) baryons in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2002-03-01)
Using the most general form of the interpolating currents of heavy baryons, the magnetic moments of heavy baryons Lambda(Q) (Q = b,c) are calculated in the framework of the light cone QCD sum rules. A comparison of our results on magnetic moments with the existing theoretical results calculated in various other frameworks 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.
