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 ...

Resonances from lattice QCD

EPJ Web of Conferences, 2018
The spectrum of hadron is mainly composed as shortly-lived states (resonance) that decay onto two or more hadrons. These resonances play an important role in a variety of phenomenologically significant processes.

QCD at finite temperature and density: Criticality [PDF]

EPJ Web of Conferences
We overview recent theoretical developments in the search for QCD critical point at finite temperature and density, including from lattice QCD, effective QCD theories, and proton number cumulants in heavy-ion collisions.

Recent results on the meson and baryon spectrum from lattice QCD

EPJ Web of Conferences, 2017
Recent lattice results on the meson and baryon spectrum with a focus on the determination of hadronic resonance masses and widths using a combined basis of single-hadron and hadron-hadron interpolating fields are reviewed.

Bottomonium evolution with in-medium heavy quark potential from lattice QCD

European Physical Journal C: Particles and Fields
The static properties and dynamic evolution of bottomonium states in a hot QCD medium are investigated through the Schrödinger equation with complex heavy quark potentials, which have been presented recently in a lattice QCD study and with three ...

Heavy-Meson Decay Constants: Isospin Breaking from QCD Sum Rules

EPJ Web of Conferences, 2017
Compared with lattice QCD, isospin breaking of heavy-meson decay constants from QCD sum rules agrees for D mesons but disagrees (by a factor of four) for B mesons.

Construction of general N-body lattice operators with arbitrary momenta

Journal of High Energy Physics
We present a systematic method for constructing lattice QCD operators for systems of an arbitrary number of particles with arbitrary momentum, spin, and internal quantum numbers. Explicit constructions are provided for one-, two-, three-, and four-hadron

QCD Phase Diagram with Imaginary Chemical Potential

EPJ Web of Conferences, 2012
We report our recent results on the QCD phase diagram obtained from the lattice QCD simulation. The location of the phase boundary between hadronic and QGP phases in the two-flavor QCD phase diagram is investigated.
