چکیده
We demonstrate that a u − d quark mass difference (which we estimate to be about 4 MeV) within quantum loops, can reproduce the effects of the Coleman-Glashow electromagnetic tadpole operator. 13.40.Dk, 13.40.Ks, 12.50.Lr Typeset using REVTEX

متن کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملEffective Lagrangian approach to weak radiative decays of heavy hadrons.
Motivated by the observation of the decay B̄ → K̄∗γ by CLEO, we have systematically analyzed the two-body weak radiative decays of bottom and charmed hadrons. There exist two types of weak radiative decays: One proceeds through the short-distance b → sγ transition and the other occurs through W -exchange accompanied by a photon emission. Effective Lagrangians are derived for the W -exchange brems...

In the NRQCD factorization for productions and decays of a quakonium the difference between the quarkonium mass and the twice of the heavy quark mass is neglected. We attempt to interpret the difference in term of NRQCD matrix elements, and consider the effect introduced by the difference in quarkonium decays. The effect is significant in these decays. Similar effect in decays of heavy-flavor h...
متن کاملMass hierarchy of leptons and hadrons within the framework of electrodynamics
Structure of leptons and hadrons within the framework of electrodynamics is considered. Muon and tau-lepton have the structure of 3 electrons. The mass of muon is defined by the section of two-photon annihilation. The mass of tau-lepton is defined by the section of three-photon annihilation. Hadrons are characterized by the structure of 5 electrons. The masses of hadrons are defined via the mas...
