TL;DR: In this article, the relation between the symmetry energy coefficient asym(A) of finite nuclei with mass number A in the semi-empirical mass formula and the nuclear matter symmetry energy Esym(ρA) at refere...
Abstract: We analyze the relation between the symmetry energy coefficient asym(A) of finite nuclei with mass number A in the semi-empirical mass formula. The nuclear matter symmetry energy Esym(ρA) at refere...

TL;DR: In this paper, the mass spectrum of BPS solitons with one kind of R-R charges was analyzed based on the Dirac-Born-Infeld (DBI) action and the fact that BPS states correspond to SUSY cycles with minimal volumes.

TL;DR: In this paper, the contribution of magnetic charges in the generalized Smarr mass formula was taken into account by using the Tomimatsu's representation of Komar integrals, and it was shown that the sum of the two electromagnetic terms in Smarr's formula can be cast into the form of a complex charge and a complex extension of the electric potential.
Abstract: The present paper clarifies how to consistently take into account the contribution of magnetic charges in the generalized Smarr mass formula by using properly the Tomimatsu's representation of Komar integrals. It is shown in particular that in all three examples of the dyonic solutions considered by us, the sum of the two electromagnetic terms in Smarr's formula can be cast into the form $\bar{\cal Q}\Phi^H_{ext}$, where ${\cal Q}$ is the complex charge and $\Phi^H_{ext}$ the complex extension of the electric potential.

TL;DR: In this paper, a simple theory of the elementary particle mass spectrum is proposed, which originates from the Dirac idea of the free electron motion and from the transformed Klein-Gordon equation, based on an equation that includes the squared mass operator having an infinite sequence of orthogonal eigenfunctions and a discrete spectrum of eigenvalues.
Abstract: A simple theory of the elementary particle mass spectrum is proposed. It originates from the Dirac idea of the free electron motion and from the transformed Klein-Gordon equation. The theory is based on an equation that includes the squared mass operator having an infinite sequence of orthogonal eigenfunctions and a discrete spectrum of eigenvalues. A discrete mass formula is derived. It yields values of mass that are in agreement with present-day empiric data for elementary particles.
