Electric dipole transitions of heavy quarkonium — •Piotr Pietrulewicz — Universität Wien

In this talk we will present the theoretical treatment of electric dipole transitions of heavy quarkonia 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 will be presented.
