متن کاملTwo-dimensional Qcd and Strings *
A review is given of recent research on two-dimensional gauge theories, with particular emphasis on the equivalence between these theories and certain string theories with a two-dimensional target space. Some related open problems are discussed.
متن کاملQCD strings with spinning quarks
A consistent description of spin within a QCD string theory has been sought for many years. The addition of dynamical spin to the bosonic string led to the development of supersymmetry and superstring theory [1]. Such theories are more realistic as unified theories of elementary particle physics than as phenomenological descriptions of hadronic states. A more realistic description of hadronic s...
متن کاملActions for Qcd-like Strings
We introduce a random lattice corresponding to ordinary Feynman diagrams, with 1/p propagators instead of the Gaussians used in the usual strings. The continuum limit defines a new type of string action with two worldsheet metrics, one Minkowskian and one Euclidean. The propagators correspond to curved lightlike paths with respect to the Minkowskian worldsheet metric. Spacetime dimensionality o...
متن کاملWhen QCD strings can break ∗
Most of the observed properties of the string breaking in lattice gauge models in presence of charged dynamical matter can be simply understood in terms of a topological property of the loop expansion in the underlying string description of confinement. Similar considerations apply also to the breaking of the adjoint string. The naive string picture of quark confinement is very simple: in the c...
