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.

QCD at finite temperature and density: Criticality [PDF]
EPJ Web of ConferencesWe 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.

Lattice results on QCD thermodynamics [PDF]
Nuclear Physics A, 2002 We review recent results on QCD at finite temperature. Main emphasis is put on a discussion of observables which are of immediate interest to experimental searches for the Quark Gluon Plasma, i.e. the phase transition temperature, the equation of state in 2 and 3-flavour QCD, the heavy quark free energy and thermal effects on hadron masses.

Bilinear quark operators in the RI/SMOM scheme at three loops
Physics Letters B, 2020 We consider the renormalization of the matrix elements of the bilinear quark operators ψ¯ψ, ψ¯γμψ, and ψ¯σμνψ at next-to-next-to-next-to-leading order in QCD perturbation theory at the symmetric subtraction point.

Scale Setting in Lattice QCD [PDF]
Proceedings of 31st International Symposium on Lattice Field Theory LATTICE 2013 — PoS(LATTICE 2013), 2014 The principles of scale setting in lattice QCD as well as the advantages and disadvantages of various commonly used scales are discussed. After listing criteria for good scales, I concentrate on the main presently used ones with an emphasis on scales derived from the Yang-Mills gradient flow.

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.
