Abstract EN
We estimate a possible η′ gluonic contribution to the self-energy of a nucleon in an effective theory.
The couplings of the topological charge density to nucleons give rise to OZI violating η′-nucleon interactions.
The one-loop self-energy of nucleon arising due to these interactions is studied using a heavy baryon chiral perturbation theory.
The divergences have been removed using appropriate form factors.
The nontrivial structure of the QCD vacuum has also been taken into account.
The numerical results are sensitive to the choice of the regulator to a nonnegligible extent.
We get the total contribution to the nucleon mass coming from its interaction with the topological charge density δmtot≅-(2.5–7.5)% of the nucleon mass.
