Noun
any particle that obeys Fermi-Dirac statistics and is subject to the Pauli exclusion principle
Source: WordNetDirac concludes with the prophetic words "We have boson variables appearing automatically in a theory that starts with only fermion variables, provided the number of fermion variables is infinite. Source: Internet
He suggested that beta decay could be explained by a four- fermion interaction, involving a contact force with no range. citation citation However, it is better described as a non-contact force field having a finite range, albeit very short. Source: Internet
If multiple fermions have the same spatial probability distribution, then at least one property of each fermion, such as its spin, must be different. Source: Internet
More precisely, because of the relation between spin and statistics, a particle containing an odd number of fermions is itself a fermion. Source: Internet
Most GUT models also fail to explain the little hierarchy between the fermion masses for different generations. Source: Internet
One of the few possible experimental tests of certain GUT is proton decay and also fermion masses. Source: Internet
