The Fermi Coupling Constant constant (0.00001166364 1/GeV²) represents the strength of Fermi's interaction which explains beta decay.
- 1.1663787(6) x 10-5 GeV-2
- 4.5437957 x 1014 J-2
The Fermi Coupling Constant, GF. is defines as:
G0F = GF/(¯h⋅c)3 = √2⋅g28⋅(m2wc4)
where:
- G0F = Fermi Coupling Constant
- g = the coupling constant of the weak interaction
- mW = the mass of the W boson.
Notes
This constant is specified with a standard uncertainty (standard deviation) of: 0.000005 E-5 GeV−2
