ΣQΛQ transition magnetic moments in light cone QCD sum rules
Using the general form of ΣQ and ΛQ (Q = b or c) currents, ΣQΛQ transition magnetic moments are calculated in 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 on transition magnetic moments are μΣcΛc = −(1.5±0.4)μN and μΣbΛb = −...

متن کاملMagnetic dipole moment of the light tensor mesons in light cone QCD sum rules
The magnetic dipole moments of the light tensor mesons f2, a2 and strange K∗0 2 (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 f2 and a2 tensor mesons, while it has a sm...
