TL;DR: In this article, an energy-dependent formula was used to evaluate the superheavy-nuclei mass defect by using both the KTUY05 and WS4 nuclear mass formulae, which reproduced successfully the value of 212 P o calculated from a combined microscopic shell and cluster model and described satisfactorily the alpha decay of heavy nuclei.
Abstract: The calculations were carried out using an energy-dependent formula, where the superheavy-nuclei mass defect was evaluated by using both the KTUY05 and WS4 nuclear mass formulae. This formula reproduced successfully the value of 212 P o calculated from a combined microscopic shell and cluster model and described satisfactorily the alpha decay of heavy nuclei. The values of the preformation probability and the cluster formation energy, and their dependence on the neutron number, confirmed the shell and subshell closures and the similarities of alpha clustering between heavy and superheavy nuclei. The calculations carried out with the WS4 mass formula showed larger alpha-clustering effects than the KTUY05.

TL;DR: In this paper, it was shown that the masses of a light pseudoscalar and a very light U-boson, the gauge particle of a U1′-group are related to each other in the Higgs sector via a simple mass formula.
Abstract: We show that the masses of a possible representant of the pseudotensor term, a light pseudoscalar and a very light U-boson, the gauge particle of a U1′-group are related to each other in the Higgs sector via a simple mass formula.

TL;DR: In this article, the mass formula for the compound partieies in the Sakata model was investigated and it was shown that the B-mauer has a charge-like character similar to the electric charge.
Abstract: Recently a unified model [) for the elementary partieies (called "the Nagoya Model") has been proposed in which the basic baryons in the Sakata model are assumed to be composed of the leptons and a new kinel of matter, B. Through the investigation of the mass formula for the compound partieies in the Sakata model, it is shown that the B-mauer has a charge like character similar to the electric charge (c= - n. On the basis of this character of the B matter, i) the mass formula (the bond character and the mass-bond relation) is reproduced, ii) the physical ground is given to Taketani's iclea,2) and his idea is developed. A dynamical law of the basic baryons within the compound particle is discussed. Remarks on new boson baryon family and photon are given.

TL;DR: In this article, it was shown that singularities at t = 0 in the Regge amplitude for unequal mass, spinless particle scattering can be cancelled by a single series of daughters, provided that the k th daughter trajectory α k ( t ) is given implicity as a function of k and t by an expansion of a certain form.

TL;DR: In this paper, the B-S equation for mesons is solved assuming that the bare mass of the straton is very large and that the interaction of straton and antistraton is instantaneous in the rest frame of the meson.
Abstract: Assuming that the bare mass of the straton is very large and that the interaction of the straton and antistraton is instantaneous in the rest frame of the meson and taking the form of V_0 γ,×γ_5+V_1γ_4×γ_4×V_2γ×γ, we solve the B-S equation for mesons. The mass formula m~2=(m_1+m_2)~2+2(m_1+m_2)E is obtained, where m_1 (m_2) is the effective mass of the straton (antistraton) inside the meson and E is the eigenvalue of the Schrdinger equation. The obtained mass spectra including both light mesons and heavy mesons agrce with experimental data. Our model may provide a possille explanation for the question why the nonrelativistic Schrdinger equation can be used even for hadronic systems composed of u, d, s stratons, though their effective mass is very small.
