Vacuum Energies of Non--Abelian String--Configurations in 3+1 Dimensions
H. Weigel, M. Quandt, N. Graham +1
We develop a method to compute the fermion contribution to the vacuum polarization energy of string--like configurations in a non--abelian gauge theory. This calculation has been h…
Quantum QED Flux Tubes in 2+1 and 3+1 Dimensions
N. Graham, V. Khemani, M. Quandt +2
We compute energies and energy densities of static electromagnetic flux tubes in three and four spacetime dimensions. Our calculation uses scattering data from the potential induce…
Kamlah Expansion and Gauge Theories
Oliver Schroeder, Hugo Reinhardt
In Yang-Mills theories, variational calculations of the Rayleigh-Ritz type face the problem that on the one hand, calculability puts severe constraints on the space of test wave fu…
Quark zero modes in intersecting center vortex gauge fields
H. Reinhardt, O. Schroeder, T. Tok +1
The zero modes of the Dirac operator in the background of center vortex gauge field configurations in and are examined. If the net flux in D=2 is larger than 1 we obt…
Nucleon Structure Functions in the Three Flavor NJL Soliton Model
O. Schroeder, H. Reinhardt, H. Weigel
We study the relevance of strange degrees of freedom for nucleon structure functions. For this purpose we employ the three flavor generalization of the collective quantization appr…
Nucleon structure functions from a chiral soliton
H. Weigel, L. Gamberg, H. Reinhardt +1
We study nucleon structure functions within the bosonized version of the Nambu-Jona-Lasinio (NJL) model in which the nucleon emerges as the soliton in the chiral field. Upon boosti…
Strangeness Contribution to the Polarized Nucleon Structure Function
O. Schroeder, H. Reinhardt, H. Weigel
The three flavor version of the Nambu-Jona-Lasinio chiral soliton model for baryons is employed to calculate the twist-2 contribution to the polarized nucleon structure function $g…
Nucleon Structure Functions from a Chiral Soliton
H. Weigel, L. Gamberg, H. Reinhardt
Nucleon structure functions are studied within the chiral soliton approach to the bosonized Nambu-Jona-Lasinio model. The valence quark approximation is employed which is justified…
