The Role of hidden ambiguities in the Linear Sigma Model with fermions
Brigitte Hiller, A. L. Mota, M. C. Nemes +2
The Linear Sigma Model (LSM) with quark degrees of freedom is used to show that radiative corrections generate undetermined finite contributions. Their origin…
The 't Hooft determinant resolution of the eta' puzzle
Alexander A. Osipov, Alex H. Blin, Brigitte Hiller
The six-quark instanton induced 't Hooft interaction, which breaks the unwanted U_A(1) symmetry of QCD, is also a sourse of semi-classical corrections to the low energy effective a…
't Hooft determinant: Fluctuatioins and Multiple Vacua
Brigitte Hiller, Alexander A. Osipov
The 't Hooft six quark flavor mixing interaction (N_f=3) is bosonized by the path integral method. The considered complete Lagrangian is constructed on the basis of the combined 't…
omega -> pi pi decay in nuclear medium
W. Broniowski, W. Florkowski, B. Hiller
We calculate the width for the omega -> pi pi decay in nuclear medium. Chiral dynamics and low-density approximation are used. At densities around twice the nuclear saturation dens…
