Phase Transitions in Particle Physics - Results and Perspectives from Lattice Quantum Chromo-Dynamics / Aarts, Gert (Swansea U. ; ECT, Trento ; Fond. Bruno Kessler, Trento) ; Aichelin, Joerg (SUBATECH, Nantes) ; Allton, Chris (Swansea U.) ; Athenodorou, Andreas (INFN, Pisa ; Cyprus Inst.) ; Bachtis, Dimitrios (Swansea U., Math. Dept.) ; Bonanno, Claudio (INFN, Florence ; Madrid, IFT ; Madrid, Autonoma U.) ; Brambilla, Nora (Munich, Tech. U.) ; Bratkovskaya, Elena (Darmstadt, GSI ; Frankfurt U. ; Helmholtz Res. Acad. Hesse for FAIR) ; Bruno, Mattia (Milan Bicocca U. ; INFN, Milan Bicocca) ; Caselle, Michele (Turin U.) et al.
Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field Theory methods. The status and future research directions for LFT investigations of Quantum Chromo-Dynamics under extreme conditions are reviewed, including properties of hadrons and of the hypothesized QCD axion as inferred from QCD topology in different phases.

How perturbative are heavy sea quarks? / Athenodorou, Andreas (Cyprus U. ; Cyprus Inst.) ; Finkenrath, Jacob (Cyprus Inst.) ; Knechtli, Francesco (Wuppertal U.) ; Korzec, Tomasz (Wuppertal U.) ; Leder, Björn (Humboldt U., Berlin) ; Krstić Marinković, Marina (Trinity Coll., Dublin) ; Sommer, Rainer (Julich, NIC ; Humboldt U., Berlin) /ALPHA Collaboration
Effects of heavy sea quarks on the low energy physics are described by an effective theory where the expansion parameter is the inverse quark mass, 1/$M$. At leading order in 1/$M$ (and neglecting light quark masses) the dependence of any low energy quantity on $M$ is given in terms of the ratio of $\Lambda$ parameters of the effective and the fundamental theory. [...]

Physical and cut-off effects of heavy sea quarks / Knechtli, Francesco (Wuppertal U.) ; Finkenrath, Jacob (Wuppertal U.) ; Leder, Björn (Wuppertal U.) ; Athenodorou, Andreas (Cyprus U.) ; Bruno, Mattia (NIC, Zeuthen ; DESY, Zeuthen) ; Sommer, Rainer (NIC, Zeuthen ; DESY, Zeuthen) ; Marinkovic, Marina (CERN)
We simulate a theory with two dynamical O($a$) improved Wilson quarks whose mass $M$ ranges from a factor eight up to a factor two below the charm quark mass and at three values of the lattice spacing ranging from 0.066 to 0.034 fm. This theory is a prototype to study the decoupling of heavy quarks. [...]

First results for SU(2) Yang-Mills with one adjoint Dirac Fermion / Athenodorou, Andreas (Swansea U. ; Cyprus U.) ; Bennett, Ed (Swansea U.) ; Bergner, Georg (Frankfurt U.) ; Lucini, Biagio (Swansea U.) ; Patella, Agostino (CERN ; Plymouth U. ; Plymouth U., Math. Stat. Dept.)
We present a first exploratory study of SU(2) gauge theory with one Dirac flavour in the adjoint representation. We provide initial results for the spectroscopy and the anomalous dimension for the chiral condensate. [...]
