A Lattice Calculation of the Isgur-Wise Function
C. Bernard, Y. Shen, A. Soni
We calculate the Isgur-Wise function () by measuring the heavy-heavy meson transition matrix element on the lattice in the quenched approximation. The standard Wilson action i…
A Study of the Kazakov-Migdal Model
Sinya Aoki, Andreas Gocksch, Yue Shen
We study numerically the SU(2) Kazakov-Migdal model of `induced QCD'. In contrast to our earlier work on the subject we have chosen here {\it not} to integrate out the gauge fields…
The Phase Diagram of the Kazakov-Migdal Model
Andreas Gocksch, Yue Shen
We have determined the phase diagram of the simplest version of a lattice model introduced in the recent work of Kazakov and Migdal. If and are the bare mass and self cou…
The Phase Diagram of a U(1) Higgs-Yukawa Model at Finite
A. Hasenfratz, K. Jansen, Y. Shen
In this paper we investigate how the phase diagram of a U(1) symmetric Higgs-Yukawa system depends on the scalar self coupling . The phase diagram of similar models with continu…
