Origin of "strong coupling constant" and "Fermi's weak coupling constant" can be understood.
Alternatively its value can be estimated form the famous Fermi weak coupling constant [F.
In a Z0 = 60 ohms system for weak coupling
(such as k = 0.
The temperature gradient term in the Richards equation provides a weak coupling
between water and heat flow processes.
2312 ), where "g" is the other force that couples to produce the weak coupling
Nucleon-structure effects not encoded in the weak coupling
A measurement at the < 1 % level could reveal the contributions from weak vertex and provide an alternative determination of the weak coupling
Because the weak boson range is so small, it can be taken to occur at a point allowing the interaction to be described by the exchange of a light meson with a weak coupling
at one end and a strong coupling at the other.
Because free neutron decay is unencumbered by the many-nucleon effects present in all other nuclear decays, measurements of the parameters that describe neutron decay can be related to the fundamental weak couplings
in a straightforward fashion.
The second step is to use this effective theory to calculate electroweak effects in the NN interaction and to determine the weak couplings from experiment.
It is clear from this table that a measurement of the weak pion coupling is required to extract information on the other weak couplings from neutron measurements.
Desplanques, Donoghue, and Holstein (DDH) estimated the nucleon-nucleon-meson weak couplings
using quark model and symmetries arguments and determined a reasonable range of values including their "best guess" values for each of the seven coupling amplitudes .
