Rotational Corrections to in the NJL Model and Charge Conjugation

Chr. V. Christov, K. Goeke, P. V. Pobylitsa

We show that the rotational corrections to , derived using the semiclassical quantization scheme in the NJL model, possess correct properties under charge conjugation.

Hyperon in Chiral Effective Quark Models

A. Blotz, M. Praszalowicz, K. Goeke

Baryonic correlation functions are calculated within an effective chiral quark model motivated by the instanton liquid model of QCD. Using a flavour SU(3) symmetry for the local fo…

Intrinsic Transverse Size Effect

J. Bolz, R. Jakob, P. Kroll +2

Two recently proposed concepts to improve the perturbative calculation of exclusive amplitudes, gluonic radiative corrections (Sudakov factor) and confinement size effects (intrins…

Loop corrections to the sphaleron transition rate in the minimal standard model

Dmitri Diakonov, Maxim Polyakov, Pavel Pobylitsa +3

The baryon number dissipation rate due to sphaleron transitions at high temperatures in the minimal standard model is evaluated. We find that this rate can be considerably suppress…

A Critical Analysis of the Proton Form Factor with Sudakov Suppression and Intrinsic Transverse Momentum

J. Bolz, R. Jakob, P. Kroll +2

The behavior of the proton magnetic form factor is studied within the modified hard scattering picture, which takes into account gluonic radiative corrections in terms of transvers…

Axial Properties of the Nucleon with -Corrections in the solitonic SU(3)-NJL-Model

A. Blotz, M. Praszalowicz, K. Goeke

Within the semibosonized SU(3)-NJL model the mass splittings of baryons and the axial vector coupling constants of the nucleon are evaluated. The mass splittings of the hyperons ar…

Heterotic Approach to the Nucleon Distribution Amplitude

M. Bergmann, N. G. Stefanis

We give an in-depth analysis of the determination procedure of the recently proposed heterotic nucleon distribution amplitude which hybridizes the best features of the Chernyak-Ogl…
