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:

GF0 = GF/(h¯c)= 2g28(mw2c4)  

where:

  • GF0 = 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
