The magnetic moments of Λb and Λc baryons in light cone QCD sum rules
نویسنده
چکیده
Using the most general form of the interpolating currents of heavy baryons, the magnetic moments of heavy baryons ΛQ (Q = b, c) are calculated in 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 are presented.

متن کاملMagnetic Dipole, Electric Quadrupole and Magnetic Octupole Moments of the ∆ Baryons in Light Cone QCD Sum Rules
Due to the very short life time of the ∆ baryons, a direct measurement on the electromagnetic moments of these systems is almost impossible in the experiment and can only be done indirectly. Although only for the magnetic dipole moment of ∆++ system there is some experimental data, the theoretical, phenomenological and lattice calculations could play crucial role. In present work, by calculatin...
متن کاملMagnetic and quadrupole moments of light spin–1 mesons in light cone QCD sum rules
The magnetic and quadrupole moments of the light–vector and axial–vector mesons are calculated in the light cone QCD sum rules. Our results for the static properties of these mesons are compared with the predictions of lattice QCD as well as other approaches existing in the literature.
متن کاملSemileptonic Λ b decay to excited Λ c baryons at order Λ QCD
Exclusive semileptonic Λb decays to excited charmed Λc baryons are investigated at order ΛQCD/mQ in the heavy quark effective theory. The differential decay rates are analyzed for the Jπ = 1/2− Λc(2593) and the J π = 3/2− Λc(2625). They receive 1/mc,b corrections at zero recoil that are determined by mass splittings and the leading order Isgur-Wise function. With some assumptions, we find that ...
