摘要：

The baryon number one soliton of the NJL model is investigated including the isoscalar vector meson omega. The euclidian effective action is separated into real and imaginary parts. The real part is regularized using Schwinger's proper time method. A consistent regularization scheme for the a priori finite imaginary part is proposed and numerical results for the static soliton energy are presented for both cases, regularized and unregularized imaginary part. Also, the various sources for the omega meson profile are discussed.
