Historical Mistake in Spontaneous Symmetry Breaking
T. Fujita, M. Hiramoto, H. Takahashi
The prediction of a massless boson after the spontaneous chiral symmetry breaking in the classic paper of Nambu and Jona-Lasinio (NJL) is shown to be wrong. Their mistake is due to…
Color triplet excitations in two dimensional QCD
Makoto Hiramoto, Takehisa Fujita
We present a novel calculation of color triplet excitations in two dimensional QCD with SU(2) colors. It is found that the lowest energy of the color triplet excitations is proport…
No Goldstone boson in NJL and Thirring models
Takehisa Fujita, Makoto Hiramoto, Hidenori Takahashi
We present an intuitive picture of the chiral symmetry breaking in the NJL and Thirring models. For the current current interaction model with the massless fermion, the vacuum is r…
New spectrum and condensate in two dimensional QCD
Takehisa Fujita, Makoto Hiramoto, Takeshi Homma
The boson mass and the condensate in two dimensional QCD with colors are numerically evaluated with the Bogoliubov vacuum. It is found that the boson mass is finite at th…
No massless boson in chiral symmetry breaking in NJL and Thirring models
Makoto Hiramoto, Takehisa Fujita
We show that the chiral symmetry breaking occurs in the vacuum of the massless Nambu-Jona-Lasinio (NJL) and Thirring models without a Goldstone boson. The basic reason of non-exist…
Ground state property of Bose-Einstein gas for arbitrary power low interaction
Makoto Hiramoto
We study Bose-Einstein gas for an arbitrary power low interaction . This is done by the Hartree Fock Bogoliubov (HFB) approach at and the mean field approa…
