Top mode standard model and extra dimensions
Michio Hashimoto, Masaharu Tanabashi, Koichi Yamawaki
We perform the most attractive channel (MAC) analysis in the top mode standard model with TeV-scale extra dimensions, where the standard model gauge bosons and the third generation…
Recovering Lorentz Invariance of DLCQ
Masa-aki Taniguchi, Shozo Uehara, Satoshi Yamada +1
We propose a way to recover Lorentz invariance of the perturbative S matrix in the Discrete Light-Cone Quantization (DLCQ) in the continuum limit without spoiling the trivial vacuu…
Zero-Mode Problem on the Light Front
Koichi Yamawaki
A series of lectures are given to discuss the zero-mode problem on the light-front (LF) quantization with special emphasis on the peculiar realization of the trivial vacuum, the sp…
Dynamical Symmetry Breaking in a Gauge Theory ``Thirring Model''
Taichi Itoh, Yoonbai Kim, Masaki Sugiura +1
Dynamical fermion mass generation is studied in the three-dimensional Thirring model reformulated as a gauge theory by introducing hidden local symmetry. The analysis by use of Sch…
Dynamical Symmetry Breaking with Large Anomalous Dimension
Koichi Yamawaki
We give an introduction to the dynamical symmetry breaking with large anomalous dimension. This is the basis of tightly bound composite Higgs models such as walking technicolor, st…
Nambu-Jona-Lasinio Model vs QCD
Koichi Yamawaki, V. I. Zakharov
We argue that the extended Nambu-Jona-Lasinio model which introduces four-quark interactions to describe hadron physics at low energies can be confronted with fundamental quantum c…
