Fermi Paradox (album)
Fermi Paradox is the 2002 (see 2002 in music) album by the band Tub Ring named after Enrico Fermi's Fermi Paradox.
Fermi's interaction
Fermi's four-fermion theory describes the weak interaction remarkably well. Unfortunately, the calculated cross-section, or probability of interaction, grows as the square of the energy formula_106. Since this cross section grows without bound, the theory is not valid at energies much higher than about 100 GeV. Here is the Fermi coupling constant, which denotes the strength of the interaction. This eventually led to the replacement of the four-fermion contact interaction by a more complete theory (UV completion)—an exchange of a W or Z boson as explained in the electroweak theory.
