Light-cone QCD Sum Rules for the Λ Baryon Electromagnetic Form Factors and its magnetic moment

Original · EN

We present the light-cone QCD sum rules up to twist 6 for the electromagnetic form factors of the Λ baryon. To estimate the magnetic moment of the baryon, the magnetic form factor is fitted by the dipole formula. The numerical value of our estimation is μΛ=-(0.64±0.04)μₙ, which is in accordance with the experimental data and the existing theoretical results. We find that it is twist 4 but not the leading twist distribution amplitudes that dominate the results.
