Section B: Light Quarks
After a brief introduction, I will review the current status of lattice calculations of the hadronic vacuum polarization and light-by-light scattering contributions to the muon anomalous magnetic moment. The errors on these contributions dominate the standard model error for this quantity and must be reduced to make the best use of new experimental measurements at Fermilab and J-PARC.

Section B: Light Quarks
The light-by-light scattering contribution to the muon anomalous magnetic moment is discussed from the Dyson-Schwinger perspective. The structure of the four-photon amplitude and the various slices of the phase space that play an important role for the muon g-2 are examined. The systematic construction of the four-photon vertex from the quark level satisfies electromagnetic gauge invariance by...

Section B: Light Quarks
The known hadron matter is made of two possible configurations: baryons, combination of 3 quarks and mesons, made by a quark and an anti-quark pair. QCD, the fundamental theory of strong interaction does not exclude the existence of states made by different combination of quarks and gluons: tetra-quarks, exotic and hybrid mesons, glue-balls. Precise determination of the hadron spectrum as well...

Based on the world’s largest samples of J/psi, psi(3686) decays collected at the BESIII detector, the progresses on the hadron spectroscopy are presented, including the PWA of J/psi radiative decays, eta and eta’ physics.

Section B: Light Quarks
An overview of a decade of elementary strangeness production results
from CLAS at Jefferson Lab will be presented. Photoproduction off the
proton of the ground state $\Lambda$ and $\Sigma^0$ states and kaons
has been instrumental in identifying the $N^*$ resonance structure of
the nucleon around 2 GeV. Spin observables, aiming at ``complete''
determination of the photoproduction...
