Hadron Masses and Decay Constants with Wilson Quarks at and 6.0
Y. Iwasaki, K. Kanaya, T. Yoshié +5
We present results of a high statistics calculation of hadron masses and meson decay constants in the quenched approximation to lattice QCD with Wilson quarks at 5.85 and 6.0…
Coherent states over Grassmann manifolds and the WKB-exactness in path integral
Kazuyuki Fujii, Taro Kashiwa, Seiji Sakoda
\(\Un{N}\) coherent states over Grassmann manifold, \(\grsmn{N}{n}\simeq\Un{N}/ (\Un{n}\times \Un{N-n})\), are formulated to be able to argue the WKB-exactness, so called the local…
1+1 dimensional QCD with fundamental bosons and fermions
Kenichiro Aoki, Tomoyasu Ichihara
We analyze the properties of mesons in 1+1 dimensional QCD with bosonic and fermionic ``quarks'' in the large $\nc$ limit. We study the spectrum in detail and show that it is impos…
More about Path Integral for Spin
Kunio Funahashi, Taro Kashiwa, Shuji Nima +1
Path integral for the spin system is reconsidered. We show that the Nielsen-Rohrlich(NR) formula is equivalent to the spin coherent state expression so that the phase space…
