An Electron Model Based on the Fine Structure Constant

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Fine Structure Constant Obtained from an Improved Calculation of the Electron G ? 2

A preliminary result is presented for an accurate determination of the ne structure constant based on an improved evaluation of the sixth-and eighth-order radiative corrections to the electron anomalous magnetic moment a e. In combination with a very precise measurement of a e , this leads to the most accurate value of obtained thus far, with an uncertainty of less than 0.004 parts per million.

A Variable Model of the Fine-Structure Constant

Recent evidence suggests that the fine-structure constant c e α h 2 = , a measure of the strength of the electromagnetic interaction between photons and electrons, is slowly increasing over cosmological timescales. High-resolution measurements of quasar spectra suggest that there has been a variation ∆α/α =-0.72 ± 0.18×10 over the past 6-10 Gyr.To model this, we propose variability in the speed...

The Meaning of the Fine Structure Constant

On the cosmological variation of the fine structure constant

A phenomenological model is proposed to explain the recent observed cosmological variation of the fine structure constant as an effect of the quantum vacuum, assuming a flat universe with cosmological constant Λ in the cases (ΩM ,ΩΛ) equal to (0.3, 0.7) and (1, 0). Because of the fourth Heisenberg relation, the lifetime of the virtual pairs of the zero-point radiation must depend on the gravita...
