Baryons in the large N limit of the massive two-dimensional Nambu-Jona-Lasinio model
Christian Boehmer, Felix Karbstein, Michael Thies
Baryons in the massive Nambu-Jona-Lasinio model in 1+1 dimensions (the massive chiral Gross-Neveu model) are studied in the limit of an infinite number of flavors. The baryon mass…

Integrating out the Dirac sea: Effective field theory approach to exactly solvable four-fermion models
Felix Karbstein, Michael Thies
We use 1+1 dimensional large N Gross-Neveu models as a laboratory to derive microscopically effective Lagrangians for positive energy fermions only. When applied to baryons, the Eu…

Divergence of the axial current and fermion density in Gross-Neveu models
Felix Karbstein, Michael Thies
The divergence of the axial current is used to relate the spatial derivative of the fermion density to the bare fermion mass and scalar/pseudoscalar condensates in 1+1 dimensional…
