Up, down, strange and charm quark masses with Nf = 2+1+1 twisted mass lattice QCD
N. Carrasco, A. Deuzeman, P. Dimopoulos +16
We present a lattice QCD calculation of the up, down, strange and charm quark masses performed using the gauge configurations produced by the European Twisted Mass Collaboration wi…
Recent developments in the tmLQCD software suite
Abdou Abdel-Rehim, Florian Burger, Alber Deuzeman +4
We present an overview of recent developments in the tmLQCD software suite. We summarise the features of the code, including actions and operators implemented. In particular, we di…
A first look at maximally twisted mass lattice QCD calculations at the physical point
A. Abdel-Rehim, Ph. Boucaud, N. Carrasco +15
In this contribution, a first look at simulations using maximally twisted mass Wilson fermions at the physical point is presented. A lattice action including clover and twisted mas…
Experiences with OpenMP in tmLQCD
A. Deuzeman, K. Jansen, B. Kostrzewa +1
An overview is given of the lessons learned from the introduction of multi-threading using OpenMP in tmLQCD. In particular, programming style, performance measurements, cache misse…
The bulk transition of QCD with twelve flavors and the role of improvement
Albert Deuzeman, Maria Paola Lombardo, Tiago Nunes da Silva +1
We study the SU(3) gauge theory with Nf=12 flavors in the fundamental representation by use of lattice simulations with staggered fermions. With a non-improved action we observe a…
On the spectrum of QCD-like theories and the conformal window
Albert Deuzeman, Maria Paola Lombardo, Elisabetta Pallante
We report on the spectrum of the SU(3) gauge theory with twelve flavours in the fundamental representation of the gauge group. We isolate distinctive features of the hadronic phase…
Bulk transitions of twelve flavor QCD and symmetry
Albert Deuzeman, Maria Paola Lombardo, Tiago Nunes da Silva +1
We present an update on our ongoing study on the nature of the bulk transition observed at strong coupling in the SU(3) gauge theory with N_f = 12 flavors in the fundamental repres…
Spectral properties of the Wilson Dirac operator in the -regime
Albert Deuzeman, Urs Wenger, Jair Wuilloud
We investigate the spectral properties of the Wilson Dirac operator in quenched QCD in the microscopic regime. We distinguish the topological sectors using the index as determined…
Lemon: an MPI parallel I/O library for data encapsulation using LIME
Albert Deuzeman, Siebren Reker, Carsten Urbach
We introduce Lemon, an MPI parallel I/O library that is intended to allow for efficient parallel I/O of both binary and metadata on massively parallel architectures. Motivated by t…
Light hadrons from Nf=2+1+1 dynamical twisted mass fermions
R. Baron, B. Blossier, P. Boucaud +15
We present results of lattice QCD simulations with mass-degenerate up and down and mass-split strange and charm (Nf=2+1+1) dynamical quarks using Wilson twisted mass fermions at ma…
Chiral symmetry of QCD with twelve light flavors
A. Deuzeman, E. Pallante, M. P. Lombardo
We study QCD with twelve light flavors at intermediate values of the bare lattice coupling. We contrast the results for the order parameter with different theoretical models motiva…
The bulk transition of many-flavour QCD and the search for a UVFP at strong coupling
Albert Deuzeman, Maria Paola Lombardo, Elisabetta Pallante
We explore the nature of the bulk transition observed at strong coupling in the SU(3) gauge theory with Nf=12 fermions in the fundamental representation. The transition separates a…

Remi Baron, Philippe Boucaud, Jaume Carbonell +17
We present results of lattice QCD simulations with mass-degenerate up and down and mass-split strange and charm (N_f = 2+1+1) dynamical quarks using Wilson twisted mass fermions at…
First results of ETMC simulations with Nf=2+1+1 maximally twisted mass fermions
R. Baron, B. Blossier, P. Boucaud +15
We present first results from runs performed with Nf=2+1+1 flavours of dynamical twisted mass fermions at maximal twist: a degenerate light doublet and a mass split heavy doublet.…
Traces of a fixed point: Unravelling the phase diagram at large Nf
Albert Deuzeman, Maria Paola Lombardo, Elisabetta Pallante
With a sufficiently high number of fundamental fermionic flavours present, Yang-Mills theory develops an infrared fixed point and becomes (quasi-)conformal in nature. The range of…
Status of ETMC simulations with Nf=2+1+1 twisted mass fermions
Rémi Baron, Philippe Boucaud, Albert Deuzeman +14
We present the status of runs performed in the twisted mass formalism with flavours of dynamical fermions: a degenerate light doublet and a mass split heavy doubl…
Hunting for the Conformal Window
A. Deuzeman, M. P. Lombardo, E. Pallante
Undeniably, the imminent activity of LHC and the quest for the nature of physics beyond the standard model have raised renewed interest in the conformal and quasi-conformal behavio…
The physics of eight flavours
Albert Deuzeman, Maria Paola Lombardo, Elisabetta Pallante
When the flavour content of QCD is increased sufficiently, the theory develops a non-trivial infra red fixed point. Thus, for a number of flavours above a certain critical value, b…
The physics of eight flavours
Albert Deuzeman, Maria Paola Lombardo, Elisabetta Pallante
We study Quantum Chromodynamics with eight flavours by use of lattice simulations and present evidence that the theory still breaks chiral symmetry in the zero temperature, continu…
