The pion superfluidity phase transition at and planes are studied in the framework of Dyson-Schwinger equations. The rainbow truncation and Gaussian effective glu…
Phase structures of neutral dense quark matter and application to strange stars

In pure-glue QCD, gluon-gluon scattering in the channel is described by a very simple equation, especially if one considers just the leading contribution to the sca…
Pion and Kaon Structure at the Electron-Ion Collider
Arlene C. Aguilar, Zafir Ahmed, Christine Aidala +48
Understanding the origin and dynamics of hadron structure and in turn that of atomic nuclei is a central goal of nuclear physics. This challenge entails the questions of how does t…
