Description
In this talk we will present the theoretical treatment of heavy quarkonia electric dipole transitions within an effective field theory formalism. Inside the effective field theory called potential nonrelativistic QCD (pNRQCD) we will account for the relativistic corrections to the decay rate in a systematic and model independent way. Former results from potential model calculations will be scrutinized and a phenomenological analysis in relation to the experimental data obtained by CLEO, BABAR & BELLE will be presented.
