Strongly correlated quantum fluids: ultracold quantum gases, quantum chromodynamic plasmas and holographic duality (2012, background): “Introduction The accepted theory of strong nuclear forces, or strong interactions, is Quantum Chromodynamics (QCD) [1], an Yang-Mills gauge theory with SU(3) gauge group.”
From controversy to precision on the sigma meson: a review on the status of the non-ordinary $f_0(500)$ resonance (2015, background): “For a general introduction we recommend the textbook [404] or the seminal reference [405].”
Properties of hot and dense matter from relativistic heavy ion collisions (2015, background): “Additional sum rules, and corrections due to finite quarkmasses can be studied using the operator product expansion [288].”
QCD at low energies (2005, background): “The recent calculations of m s by QCD sum rules [21], from the τ -decay data [22] [23] and on lattice [19] [24], are in a not quite good agreement with one another.”
