Phase diagram of a 1 dimensional spin-orbital model
Chigak Itoi, Shaojin Qin, Ian Affleck
We study a 1 dimensional spin-orbital model using both analytical and numerical methods. Renormalization group calculations are performed in the vicinity of a special integrable po…
Nonuniqueness of Canonical Ensemble Theory arising from Microcanonical Basis
Sumiyoshi Abe, A. K. Rajagopal
Given physical systems, counting rule for their statistical mechanical descriptions need not be unique, in general. It is shown that this nonuniqueness leads to the existence of va…
Form factors of the SU(2) invariant massive Thirring model with boundary reflection
H. Furutsu, T. Kojima, Y. -H. Quano
The SU(2) invariant massive Thirring model with a boundary is considered on the basis of the vertex operator approach. The bosonic formulae are presented for the vacuum vector and…
Effect of sigma(600)-Production in pp_bar to 3pi0 at rest
Muneyuki Ishida, Toshihiko Komada, Shin Ishida +3
The pi0 pi0 mass spectra and angular distributions around KK_bar-threshold and at 1.5 GeV in pp_bar(at rest) to 3pi0 in the Crystal Barrel experiment are reanalyzed by applying the…
Isoscalar Giant Quadrupole Resonance State in the Relativistic Approach with the Momentum-Dependent Self-Energies
Tomoyuki Maruyama, Satoshi Chiba
We study the excited energy of the isoscalar giant quadrupole resonance with the scaling method in the relativistic many-body framework. In this calculation we introduce the moment…
Direct CP, T and/or CPT violations in the K^0-\bar{K^0} system - Implications of the recent KTeV results on decays -
Y. Takeuchi, S. Y. Tsai
The recent results on the CP violating parameters Re(e'/e) and Δϕ= ϕ_{00}-ϕ_{+-} reported by the KTeV Collaboration are analyzed with a view to constrain CP, T and CPT violations i…
