Dynamical Twisted Mass Fermions with Light Quarks
hep-lat 2007-01 conditional novelty 6.0 of 10

Dynamical twisted-mass lattice QCD at maximal twist reaches 300 MeV pions and fits NLO chiral perturbation theory to extract F = 121.3(7) MeV, l3 = 3.65(12) and l4 = 4.52(6), statistical errors only.
HMC algorithm with multiple time scale integration and mass preconditioning
hep-lat 2005-06 conditional novelty 5.0 of 10

Mass preconditioning plus multiple time scale integration makes HMC for light Wilson quarks about as cheap as domain-decomposition preconditioning, and cheaper than plain leapfrog, at beta=5.6.
tmLQCD: a program suite to simulate Wilson Twisted mass Lattice QCD
hep-lat 2009-05 accept novelty 4.0 of 10

tmLQCD is a documented, GPL-licensed, MPI-parallel C code implementing Hybrid Monte Carlo with mass preconditioning and multiple time scales for Wilson twisted mass lattice QCD, shipped with sample inputs and expected...
Nuclear Physics from Lattice QCD
hep-lat 2010-04 conditional novelty 3.0 of 10

Lattice QCD has produced first calculations of two-, three- and four-baryon systems, and this review argues the field can reach physical quark masses and multi-nucleon interactions within a decade given exa-scale computing.
Twisted mass lattice QCD
hep-lat 2007-07 accept novelty 3.0 of 10

Wilson twisted mass QCD at maximal twist removes order-a lattice artifacts from parity-even observables with only the critical mass tuned, at the price of order-a-squared parity and isospin breaking and a nontrivial c...
