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…
Exotic Baryons in Two-Dimensional QCD
John Ellis, Yitzhak Frishman
Two-dimensional QCD has often been used as a laboratory for studying the full four-dimensional theory, providing, for example, an explicit realization of baryons as solitons. We re…
Meson-Baryon Scattering in QCD_2 for any Coupling
John Ellis, Yitzhak Frishman, Marek Karliner
Extending earlier work on strong-coupling meson-baryon scattering in QCD_2, we derive the effective meson-baryon action for any value of the coupling constant, in the large-N_c lim…
Scattering and Resonances in QCD_2
Yitzhak Frishman, Marek Karliner
Extending previous works on the spectrum of QCD_2, we now investigate the 2D analogue of meson-baryon scattering. We use semi-classical methods, perturbing around classical soliton…
The Rule in the Light of Two-Dimensional QCD
John Ellis, Yitzhak Frishman, Amihay Hanany +1
We calculate in QCD the ratios of baryonic matrix elements of and four-fermion operators, with a view to understanding better the mechanism of enha…
On the Stability of Quark Solitons in QCD
Yitzhak Frishman, Amihay Hanany, Marek Karliner
We critically re-examine our earlier derivation of the effective low energy action for QCD in 4 dimensions with chiral fields transforming non-trivially under both color and flavor…
