8 个问题

  1. Nature of the P11 Roper resonance N(1440): particle-like bare-state counterpart or dynamically generated state (the 1967 Maskawa-Kondo-Maki mixing question)

  2. Multiplicity of superconducting solutions and the cutoff-free strong-coupling regime in the Maskawa-Nakajima vector-gluon model

  3. Existence and order of the finite-temperature chiral phase transition in Nf=8N_f=8 QCD

  4. Continuum-limit status of the light flavor-singlet scalar in many-flavor SU(3) gauge theory: dilatonic physics or lattice artifact?

  5. Continuum and chiral-limit status of eight-flavor SU(3) QCD: walking versus conformality, the light flavor-singlet scalar, and the mass anomalous dimension

  6. Corrections to the conformal hyperscaling relation beyond the ladder Schwinger-Dyson approximation, and reliable extraction of the infrared-fixed-point anomalous dimension from lattice data

  7. Infrared phase of massless twelve-flavor SU(3) QCD: infrared conformality or spontaneous chiral symmetry breaking?

  8. Walking or conformal: the infrared phase of SU(3) gauge theory with eight fundamental fermions (Nf=8N_f=8 QCD)
