Constraints for the QCD phase diagram from imaginary chemical potential
Constraints QCD phase diagram imaginary chemical potential
2011/1/13
We present unambiguous evidence from lattice simulations of Nf = 3 QCD for two tricritical
points in the (T,m) phase diagram at fixed imaginary m/T = ip /3 mod. 2p /3, one in the light

Finite temperature QCD at fixed Q with overlap fermions
Finite temperature QCD fixed Q overlap fermions
2011/1/13
We present some preliminary results of the project on finite temperature QCD with overlap fermions at KEK.We performed a series of simulations to assess the effects of fixing the topological sector at...
We construct the transfer matrix for the ghost sector of partially quenched QCD. This transfer
matrix is not hermitian, but we show that it is still bounded. We thus expect that all euclidean correla...
Non-perturbative renormalization of quark mass in Nf=2+1 QCD with the Schroedinger functional scheme
Non-perturbative renormalization of quark mass Nf=2+1 QCD Schroedinger functional scheme
2011/1/13
We present an evaluation of the quark mass renormalization factor for Nf = 2 + 1 QCD.The Schrödinger functional scheme is employed as the intermediate scheme to carry out onperturbative running f...

We study the gluon propagator in the Landau gauge in SU(3) lattice QCD at b =5.7, 5.8 and
6.0 at the quenched level.

Symmetry energy of dense matter holographic QCD
2011/1/7
We study the nuclear symmetry energy of dense matter using holographic QCD. To this end, we
consider two flavor branes with equal quark masses in a D4/D6/D6 model. We find that at high
density the s...
Non-perturbative running of the coupling from four flavour lattice QCD with staggered quarks
Non-perturbative running coupling from four flavour lattice QCD staggered quarks
2011/1/14
Using the Schrödinger functional (SF) with a single staggered fermion field we calculate the SF
coupling in four-flavour QCD for a wide range of energies and lattice sizes up to L/a = 16.
Preli...

Progress in calculating the spectrum of excited baryons and mesons in lattice QCD is described.
Correlation matrices of sets of spatially-extended hadron operators have been studied and their
effect...
The study of the Three Nucleon Force in full QCD Lattice calculations
Three Nucleon Force full QCD Lattice calculations
2011/1/7
We study the three nucleon force in the triton channel using dynamical clover fermion lattice
QCD. The Nambu-Bethe-Salpeter wave function is utilized to obtain the potentials among three
nucleons.
The low-lying even-parity states of the nucleon are explored in lattice QCD using the PACS-CS
collaboration 2+1-flavor dynamical-QCD gauge-field configurations made available through the In-ternation...
Recent progress on nuclear potentials from lattice QCD
Recent progress nuclear potentials lattice QCD
2011/1/14
A new method for nuclear potentials is reviewed. The strategy to extract the potential from the
Nambu-Bethe-Salpeter wave function in lattice QCD is explained and the first result based on the method...
How the Quark Number fluctuates in QCD at small chemical potential
Quark Number fluctuates QCD small chemical potential
2011/1/14
We discuss the distribution of the quark number over the gauge fields for QCD at nonzero quark
chemical potential. As the quark number operator is non-hermitian, the distribution is over the
complex...

We perform a non-perturbative lattice calculation of the P-wave pion-pion scattering phase in
the -meson decay channel using two flavors of maximally twisted mass fermions at pion masses
ranging fr...
Naively resummed perturbative approximations to the thermodynamic functions of QCD do not converge at phenomenologically relevant temperatures. Here we review recent results of a three-loop hard-therm...

We conclude our investigations on the QCD cross-over transition temperatureswith 2+1 staggered
flavours and one-link stout improvement. We extend our previous two studies [Phys. Lett. B643
