An allegedly complete calculation of the neutron-proton mass difference in the Skyrme model reported recently, claiming a correct sign and a 16% agreement with experiment, is re-examined. After analytical and numerical inaccuracies in the reportes calculation are eliminated, it gives a value for the mass difference which, both in magnitude and sign, is different from that reported, and is consistent with the expectation that the calculation merely represents the electromagnetic contribution to, and not a complete calculation of, the neutron-proton mass difference in the Skyrme model.

TAU-MU-E NONUNIVERSALITY AS INDICATION OF ORDINARY AND EXOTIC LEPTON MIXING Alıyev, Tahmasıb; YILMAZ, O (1992-09-17) Possible deviations from the tau-mu-e universality are discussed in the framework of the standard model with four families and in that of the E6 model. It is shown that the experimental study of spin asymmetry in the process e+e- --> Z --> tau+tau- will give direct information on the real tau-nonuniversality due to the mixing of the usual and exotic fermions.
Electromagnetic mass differences of nucleons and Δ-baryons in the skyrme model Ebrahim, A. ; Savcı, Mustafa (1989-08-17) The numerical values predicted for the electromagnetic mass differences of nucleons and Δ-baryons in the Skyrme model are obtained and inaccuracies in previously reported values are pointed out.
Energy distribution of the universe in the Bianchi type II cosmological models Aydogdu, O (Wiley, 2006-04-01) Using the energy-momentum complexes of Tolman, Papapetrou and Weinberg, the total energy of the universe in Locally Rotationally Symmetric (LRS) Bianchi type II models is calculated. The total energy is found to be zero due to the matter plus field. This result supports the viewpoint of Tryon, Rosen and Albrow. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
Charged lepton flavor physics and extra dimensions Iltan, E. I. (World Scientific Pub Co Pte Lt, 2007-06-28) We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero-mode profile. We observe that the numerical values of the physical quantities studied enhance with the ...
FORM-FACTOR OF RADIATIVE PION DECAY IN QCD Alıyev, Tahmasıb (World Scientific Pub Co Pte Lt, 1991-08-20) Axial form-factor of the radiative decay of charged pion is calculated using QCD sum rules method for non-diagonal correlator. For the ratio gamma = F(A)(0)/F(V)(0) we find gamma = 0.6 +/- 0.15.
