Description

In the early 1970's, evidence that the masses of strongly interacting particles increased without limit as their internal angular momentum increased led the Japanese theorist Yoichiro Nambu to propose that the quarks inside of these particles are ''tied'' together by strings. Today the string theories which emerged from this idea are being examined as candidates for the ultimate theory of nature, while we know that the strong interactions are instead described by quantum chromodynamics (QCD), the field theory in which quarks interact through a ''color'' force carried by gluons. Though it is therefore not fundamentally a string theory, numerical simulations ... continued below

Description

In the early 1970's, evidence that the masses of strongly interacting particles increased without limit as their internal angular momentum increased led the Japanese theorist Yoichiro Nambu to propose that the quarks inside of these particles are ''tied'' together by strings. Today the string theories which emerged from this idea are being examined as candidates for the ultimate theory of nature, while we know that the strong interactions are instead described by quantum chromodynamics (QCD), the field theory in which quarks interact through a ''color'' force carried by gluons. Though it is therefore not fundamentally a string theory, numerical simulations of QCD (''lattice QCD'') have demonstrated that Nambu's conjecture was essentially correct: in chromodynamics, a string-like chromoelectric flux tube forms between distant static charges, leading to quark confinement and a potential energy between a quark and the other quarks to which it is tied which increases linearly with the distance between them. The phenomenon of confinement is the most novel and spectacular prediction of QCD - unlike anything seen before.
