abstract

I explore the possibility of finding an equivalent string representation of two dimensional QCD. I develop the large N expansion of the ${\rm QCD_2}$ partition function on an arbitrary two dimensional Euclidean manifold. If this is related to a two-dimensional string theory then many of the coefficients of the ${1\over N}$ expansion must vanish. This is shown to be true to all orders, giving strong evidence for the existence of a string representation.

    hep-th 2019-08 conditional novelty 8.0 of 10

    Two-dimensional adjoint QCD has mixed 't Hooft anomalies that force spontaneous chiral symmetry breaking for most N and partial deconfinement of N-ality N/2 charges for even N.

  2. The String Dual to Two-dimensional Yang-Mills Theory Revisited

    hep-th 2025-02 conditional novelty 6.0 of 10

    Chiral two-dimensional Yang-Mills theory at large N is proposed to be dual to a stationary subsector of Gromov-Witten theory deformed by an area-dependent transposition interaction and an Omega-point compactification ...

  3. Topological effects in continuum 2d $U(N)$ gauge theories

    hep-th 2019-08 conditional novelty 6.0 of 10

    For 2d U(N) gauge theory on a sphere, the large-N topological susceptibility vanishes below the Douglas-Kazakov transition and becomes nonzero above it, unlike the pure U(1) value.

  4. Bosonization, BTZ Black Hole Microstates, and Logarithmic Correction to Entropy

    hep-th 2025-08 conditional novelty 4.0 of 10

    BTZ black hole microstates under collective-field boundary conditions are labeled by Young diagrams, and the logarithmic correction to their entropy is -1/2, one-loop exact and identical for two boundary Hamiltonians.
