Chiral Symmetry Breaking and Quark Bilinear Condensate in Large N QCD
Ryosuke Sato
We discuss spontaneous chiral symmetry breaking and quark bilinear condensate in large QCD. It has been known that the existence of meson is implied in large QCD a…

Negative Mode Problem of False Vacuum Decay Revisited
Ryusuke Jinno, Ryosuke Sato
We study negative modes around the Coleman-de Luccia bounce solution. The conditions for the appearance of an infinite number of the negative modes do not coincide between Lagrangi…

O() Invariance of the Multi-Field Bounce
Kfir Blum, Masazumi Honda, Ryosuke Sato +2
In his 1977 paper on vacuum decay in field theory: The Fate of the False Vacuum, Coleman considered the problem of a single scalar field and assumed that the minimum action tunnell…
