The fine-structure constant 伪 [1] is a constant in physics that plays a fundamental role in the electromagnetic interaction. It is a dimensionless constant, defined as: (1) being q the elementary charge, 蔚0 the vacuum permittivity, h the Planck constant and c the speed of light in ...
Throughout his life, Pauli had been preoccupied with the question of why the fine structure constant, a dimensionless fundamental constant, has a value nearly equal to 1/137. 終其一生,泡利時常思考一個奇異的問題──為什麼精细结构常数(一個無量綱的基本常數)會近似於1/137。 LASER-wikipedia2 ...
Why is the value of the fine-structure constant what it is? Today, we have an apparently correct and essentially complete description of all of elementary particle physics in terms of a gauge theory 1 . If the underlying gauge group is simple 2,3 , all three elementary particle interactions...
The fine-structure constant was introduced in 1916 to quantify the tiny gap between two lines in the spectrum of colors emitted by certain atoms. The closely spaced frequencies are seen here through a Fabry-Pérot interferometer. As fundamental constants go, the speed of light, c, enjoys all ...
Time-variability of the fine-structure constant expected from the Oklo constraint and the QSO absorption lines The data from the QSO absorption lines indicating a nonzero time-variability of the fine-structure constant has been re-analyzed on the basis of a "damped-... Y Fujii - 《Physics Le...

Calculation of the Dirac hydrogen atom spectrum in the framework of dynamical fine structure constant (alpha) variability discloses a small departure in the laboratory from Sommerfeld's formula for the fine structure shifts, possibly measurable today. And for a distant object in the universe, the ...
A relativistic quantum mechanics is formulated in which all of the interactions are in the four-momentum operator and Lorentz transformations are kinematic. Interactions are introduced through vertices, which are bilinear in fermion and antifermion creat
