On bound-states of the Gross Neveu model with massive fundamental fermions
Yitzhak Frishman, Jacob Sonnenschein
In the search for QFT's that admit boundstates, we reinvestigate the two dimensional Gross-Neveu model, but with massive fermions. By computing the self-energy for the auxiliary bo…
Large N Chern-Simons with massive fundamental fermions - A model with no bound states
Yitzhak Frishman, Jacob Sonnenschein
In a previous paper, we analyzed the theory of massive fermions in the fundamental representation coupled to a U(N) Chern-Simons gauge theory in three dimensions at level K. It was…
Breaking conformal invariance- Large N Chern-Simons theory coupled to massive fundamental fermions
Yitzhak Frishman, Jacob Sonnenschein
We analyze the theory of massive fermions in the fundamental representation coupled to a U(N) Chern-Simons gauge theory at level K. It is done in the large N, large K limits where…
Tetraquarks, their Masses and Decays in QED_2
Yitzhak Frishman, Marek Karliner
Recent observations by Belle and BESIII of charged quarkonium-like resonances give new stimulus for theoretical investigation of exotic hadrons in general and heavy tetraquarks in…
Non-Perturbative Field Theory - From two dimensional conformal field theory to QCD in four dimensions
Yitzhak Frishman, Jacob Sonnenschein
This note is based on the summary of our book entitled "Non-perturbative field theoryfrom two dimensional conformal field theory to QCD in four dimensions", published recently by C…
The Adjoint Vacuum Sector of Massless QCD2
A. Abrashkin, Y. Frishman, J. Sonnenschein
We consider a "one current" state, obtained by appication of a color current on the "adjoint" vacuum, in , with quarks in fundamental representation. The quarks are taken to…
