TL;DR: The low energy effective Lagrangian for SU(2) supersymmetric Yang-Mills theory coupled to N_F < 4 massless matter fields is derived from the BPS mass formula using asymptotic freedom and assuming that the number of strong coupling singularities is finite.

TL;DR: In this paper, the effect of a possible isotensor γ N Δ coupling on the isobaric-multiplet mass equation was investigated and it was found that discrepancies between theory and experiment for the d -term cannot be explained by the contribution from isotensor electromagnetic currents.

TL;DR: In this paper, the effect of vacuum polarization on the ground-state mass systematics of nuclei is considered and its contribution to the ground state energy of heavy nuclei was found to be a few MeV and can be simulated using an effective nuclear radius in the Coulomb energy term of the mass formula.

TL;DR: In this article, the subatomic particle mass spectrum in the 100 MeV to 7,000 MeV range was retrodicted to a first approximation using the Kerr solution of General Relativity.
Abstract: Representative members of the subatomic particle mass spectrum in the 100 MeV to 7,000 MeV range are retrodicted to a first approximation using the Kerr solution of General Relativity. The particle masses appear to form a restricted set of quantized values of a Kerr-based angular momentum-mass relation: m = (sqrt n)(M), where values of n are a set of discrete integers and M is a revised Planck mass. A fractal paradigm manifesting global discrete self-similarity is critical to a proper determination of M, which differs from the conventional Planck mass by roughly 19 orders of magnitude. This exceedingly simple and generic mass equation retrodicts the masses of a representative set of 27 well-known particles with an average relative error of 1.6%. A more rigorous mass formula, which includes the total spin angular momentum rule of Quantum Mechanics, the canonical spin values of the particles, and the dimensionless rotational parameter of the Kerr angular momentum-mass relation, is able to retrodict the masses of the 8 dominant baryons in the 900 MeV to 1700 MeV range at the 99.7% level, on average.
