An empirical hadron mass formula based on the rishon hypothesis of Harari is proposed. The calculated masses for 1/sup -/ mesons and 3/2/sup +/ baryons are found to be in good agreement with available data. We predict m/sub( Upsilont/t-bar) = 39.06 GeV and if a fourth generation exists, m/sub( Upsilonb//sup prime/b-bar/sup prime/) = 103.80 GeV and m ...

Generalized Algebraic Mass Formulas. I
Journal of Mathematical Physics, 1970It is shown that the SL(2, C)-Poincaré associative algebraic model of Böhm can be extended without essential difficulty to an SL(2, C)-de Sitter model which gives rise to a meson mass formula with both spin and isospin dependence.

Mass Extrapolation and Mass Formulae
1972For several reasons, the interest of nuclear physicists is continuously shifting towards nuclei further and further removed from stability. In low mass nuclides one wants to study nuclei with high values of the isospin. For very heavy ones, the matter of the possible existence of an island of stability near at mass number 300 is a popular subject.

Semiempirical atomic mass formula
Nuclear Physics A, 1975Abstract An atomic mass formula based on the liquid-drop model with shell and deformation energies determined from the Nilsson model and BCS pairing energy has been adjusted simultaneously to ground-state binding energies and to fission barrier heights. A short table of calculated values is included, and additional calculations are available.

Critical remarks are made concerning mass tables in general and the mass table based on mass relationships in particular. Specific criteria for acceptability of a table are formulated. Two methods — which form a logical sequence — of using these relationships to predict masses, are described.

Physical Review C, 2014
In this paper we improve an empirical mass formula constructed by J\"anecke and collaborators. This formula is enlightened by the Garvey-Kelson mass relations. The new version of the J\"anecke formula reproduces 2275 atomic masses with neutron number $N\ensuremath{\ge}10$ and proton number $Z\ensuremath{\ge}6$, at an average accuracy of 128 keV, by ...

Nuclear Physics A, 1973
Abstract A mass fit of the droplet model is presented 1 ). To gain more confidence in the values of the thirteen coefficients used, we fitted in addition the best-known isobar parabolae. By this procedure the position and the width of the β-valley are fitted and the symmetry J and the surface stiffness Q proved to be the only relevant parameters.

General mass formula in broken supersymmetry
Physical Review D, 1979The mass formula summation/sub J/(- 1)/sup 2J/(2J + 1) m/sub J/ /sup 2/ = 0 is derived for a very general class of interactions with spontaneously broken supersymmetry. It shows the vanishing of the graded trace of the square of the mass operator, with m/sub J/ the mass associated with a (real) field of spin J.

The irreducible mass of Christodoulou-Ruffini-Hawking mass formula
The Sixteenth Marcel Grossmann Meeting, 2022We reveal three new discoveries in black hole physics previously unexplored in the Hawking era. These results are based on the remarkable 1971 discovery of the irreducible mass of the black hole by Christodoulou and Ruffini, and subsequently confirmed by Hawking. (1) The Horizon Mass Theorem states that the mass at the event horizon of any black hole

Physical Review C, 2014
A simple formula for ground state nuclear masses based on the microscopic-macroscopic approach is proposed. Considering a set of 2353 nuclei with $Z\ensuremath{\ge}8$ and $N\ensuremath{\ge}8$, the formula yields an rms deviation of just 266 keV. A few applications, including the loosely bound proton rich nuclei, superheavy nuclei, and cluster emitters,
