 Scale hierarchy in high-temperature QCD / Akerlund, Oscar ; de Forcrand, Philippe Because of asymptotic freedom, QCD becomes weakly interacting at high temperature: this is the reason for the transition to a deconfined phase in Yang-Mills theory at temperature $T_c$.

 Rescuing Quadratic Inflation / Ellis, John ; Fairbairn, Malcolm ; Sueiro, Maria Inflationary models based on a single scalar field $\phi$ with a quadratic potential $V = \frac{1}{2} m^2 \phi^2$ are disfavoured by the recent Planck constraints on the scalar index, $n_s$, and the tensor-to-scalar ratio for cosmological density perturbations, $r_T$.
