Spectrum and wave functions of excited states in lattice gauge theory [PDF]

, 2008
We suggest a new method to compute the spectrum and wave functions of excited states. We construct a stochastic basis of Bargmann link states, drawn from a physical probability density distribution and compute transition amplitudes between stochastic ...

B-physics from lattice QCD...with a twist [PDF]

, 2012
We present a precise lattice QCD determination of the b-quark mass, of the B and Bs decay constants and first results for the B-meson bag parameters.

CHARMONIA FROM LATTICE QCD [PDF]

International Journal of Modern Physics A, 2006
Recent lattice QCD results on charmonium properties are reviewed. I comment on molecules and hybrid states as well as on future studies of states near strong decay thresholds.

Meson Correlators in Finite Temperature Lattice QCD [PDF]

, 2000
We analyze temporal and spatial meson correlators in quenched lattice QCD at T>0. Below T_c we observe little change in the meson properties as compared with T=0.

Instanton dynamics in finite temperature QCD via holography

Nuclear Physics B, 2015
We investigate instantons in finite temperature QCD via Witten's holographic QCD. To study the deconfinement phase, we use the setup proposed in [1]. We find that the sizes of the instantons are stabilized at certain values both in the confinement and ...
