Strange S--Wave Excitation of the NJL Soliton
H. Weigel, R. Alkofer, H. Reinhardt
The recently developed method to investigate mesonic fluctuations off the chiral soliton in the Nambu--Jona--Lasinio model is applied to kaons in the S--wave channel. It is shown t…
Hyperons in the Bound State Approach to the Nambu--Jona-Lasinio Chiral Soliton
H. Weigel, R. Alkofer, H. Reinhardt
For the Nambu--Jona--Lasinio (NJL) model in the proper time regularization scheme the chiral soliton is investigated for the case of three flavors within the framework of the bound…
Non-Trivial SU(N) Instantons and Exotic Skyrmions
H. Reinhardt, K. Langfeld
The classical Yang-Mills equations are solved for arbitrary semi-simple gauge groups in the Schwinger-Fock gauge. A new class of SU(N) instantons is presented which are not embeddi…
Casimir Effect of Strongly Interacting Scalar Fields
K. Langfeld, F. Schm"user, H. Reinhardt
Non-trivial -theory is studied in a renormalisation group invariant approach inside a box consisting of rectangular plates and where the scalar modes satisfy periodic bounda…
The Nambu-Jona-Lasinio Chiral Soliton with Constrained Baryon Number
J. Schlienz, H. Weigel, H. Reinhardt +1
A regularization for the baryon number consistent with the energy in the Nambu-Jona-Lasinio model is introduced. The soliton solution is constructed with the regularized baryon num…
Diquark electromagnetic form factors in a Nambu-Jona-Lasinio model
C. Weiss, A. Buck, R. Alkofer +1
Electromagnetic properties of diquarks are investigated in the framework of a color-octet Nambu-Jona-Lasinio model, which describes baryons as bound states of diquarks and quarks.…
