Critical behavior of strongly coupled lattice QCD at finite temperature
Yasuo Umino
We study the critical behavior of lattice Quantum Chromodynamics (QCD) in the strong coupling approximation with Kogut-Susskind and Wilson fermions at finite temperature () and…
Equation of state of strongly coupled QCD at finite density
Yasuo Umino
Using an effective strongly coupled lattice QCD Hamiltonian and Wilson fermions we calculate the equation of state for cold and dense quark matter by constructing an ansatz which e…
Hamiltonian lattice QCD at finite density: equation of state in the strong coupling limit
Yasuo Umino
The equation of state of Hamiltonian lattice QCD at finite density is examined in the strong coupling limit by constructing a solution to the equation of motion corresponding to an…

Yasuo Umino
We calculate the equation of state of strongly coupled Hamiltonian lattice QCD at finite density by constructing a solution to the equation of motion corresponding to an effective…
Diagonalization of the strongly coupled lattice QCD Hamiltonian
Yasuo Umino
We construct a solution to the equation of motion of Hamiltonian lattice QCD in the strong coupling limit using Wilson fermions which exactly diagonalizes the Hamiltonian to second…
The 't Hooft interaction at finite T and : Beyond the mean field theory
Yasuo Umino, Vicente Vento
We use the N-quantum approach (NQA) to quantum field theory to construct a solution of the two flavor effective instanton induced `t Hooft interaction model valid for any temperatu…
N-quantum approach to quantum field theory at finite T and : the NJL model
Yasuo Umino, Vicente Vento
We extend the N-quantum approach to quantum field theory to finite temperature () and chemical potential () and apply it to the NJL model. In this approach the Heisenberg fie…
Baryon resonances in a chiral confining model (I)
Y. Umino, M. K. Banerjee
In this two part series a chiral confining model of baryons is used to describe low--lying negative parity resonances , , and in the mean field approximation.…
Exchange Current Corrections to Neutrino-Nucleus Scattering. I. Nuclear Matter
Y. Umino, J. M. Udias
Relativistic exchange current corrections to the impulse approximation in low and intermediate energy neutrino--nucleus scattering are presented assuming non--vanishing strange qua…
Exchange Current Corrections to Neutrino--Nucleus Scattering
Y. Umino, J. M. Udias, P. J. Mulders
Relativistic exchange current corrections to neutrino--nucleus cross sections are presented assuming non--vanishing strange quark form factors for the constituent nucleons. For cha…
Electromagnetic Decays of Hyperons (II)
Y. Umino, F. Myhrer
Excited negative parity hyperon masses are calculated in a chiral bag model in which the pion and the kaon fields are treated as perturbations. We also calculate the hadronic width…
