Abstract
Elementary mass difference of baryon and boson is discussed on fundamental triplet model, taking into account the electromagnetic self energy of fundamental triplet (Δm), Coulomb force and magnetic hyperfine interaction between triplets. Electromagnetic mass difference is successfully explained by taking Δm = -1.9 Mev for baryon (Δm = -7 Mev for boson), the mean separation ≪r> = 0.4 × 10-13 cm between triplets, and the anomalous magnetic moment of triplet µ= 2.6 e/2 Mp. Baryons and bosons are described by 56 and 35 representation of SU(6). In our model electromagnetic mass difference K+ - K0 is easily explained by the electromagnetic mass difference of fundamental triplet, while this cannot be explained from the conventional field theory, where K meson is assumed to be elementary. In our model the electromagnetic mass difference π+ - π0 is due to Coulomb force and hyperfine interaction between triplet and antitriplet. The electromagnetic mass difference of boson is also discussed from the model where bosons are compound state of baryon and antibaryon, but this model is found to be implausible.Keywords
