Physical Review D, 1976
The relation between the masses and mixing angle in a nonet of mesons is studied in a simple quark-gluon picture. We find that both the splitting of ${{\ensuremath{\mu}}_{\ensuremath{\eta}}}^{2}$ from ${{\ensuremath{\mu}}_{\ensuremath{\pi}}}^{2}$ and the departure of ${\ensuremath{\theta}}_{P}$ from ${\ensuremath{\theta}}_{\mathrm{ideal}}$ are due to ...

Mass formulae for Λ-hypernuclei
Pramana, 1982Simple considerations regarding the Hamiltonian and the ground state wavefunctions of Λ-hypernuclei are used to derive several mass formulae. The parameters that occur in the mass formulae are determined by fitting the experimental binding energies.

Dynamical Groups and Mass Formula
Physical Review, 1965The homogeneous Lorentz group and the 4+1 de Sitter group are interpreted as the dynamical groups of a nonrelativistic and a relativistic "rotator," respectively. In an irreducible representation of the latter group we obtain for certain states the mass formula ${m}^{2}={{m}_{0}}^{2}+{\ensuremath{\lambda}}^{2}j(j+1)$.

Quark masses using Barut-like mass formula
Journal of Physics G: Nuclear and Particle Physics, 1990An extension of Barut's (1979) lepton mass formula to quark masses, using lepton-quark symmetry is applied to obtain the masses of the third and fourth generation quarks. The t-quark mass is found to be quite a bit smaller than present estimates.

New global atomic mass formulas
International Journal of Modern Physics B, 2017We illustrate the improved empirical methods of estimating atomic masses using Garvey–Kelson like local relations and global equations using generic point functions.

Meson mass formula from duality
Physical Review D, 1975A general mass formula for meson levels in the symmetric-group dual resonance model is written in terms of the corresponding quark-model quantum numbers. (AIP)
