Excited Scalar and Pseudoscalar Mesons in the Extended Linear Sigma Model
Denis Parganlija, Francesco Giacosa
We present an in-depth study of masses and decays of excited scalar and pseudoscalar states in the Extended Linear Sigma Model (eLSM). The model also contains ground-sta…
Phases of dense matter with holographic instantons
Florian Preis, Andreas Schmitt
We discuss nuclear matter and the transition to quark matter in the decompactified limit of the Sakai-Sugimoto model. Nuclear matter is included through instantons on the flavor br…
Holographic QCD predictions for production and decay of pseudoscalar glueballs
Frederic Brünner, Anton Rebhan
The top-down holographic Witten-Sakai-Sugimoto model for low-energy QCD, augmented by finite quark masses, has recently been found to be able to reproduce the decay pattern of the…
Layers of deformed instantons in holographic baryonic matter
Florian Preis, Andreas Schmitt
We discuss homogeneous baryonic matter in the decompactified limit of the Sakai-Sugimoto model, improving existing approximations based on flat-space instantons. We allow for an an…
Simulating collisions of thick nuclei in the color glass condensate framework
Daniil Gelfand, Andreas Ipp, David Müller
We present our work on the simulation of the early stages of heavy-ion collisions with finite longitudinal thickness in the laboratory frame in 3+1 dimensions. In particular we stu…
Early quark production and approach to chemical equilibrium
D. Gelfand, F. Hebenstreit, J. Berges
We perform real-time lattice simulations of out-of-equilibrium quark production in non-Abelian gauge theory in 3+1-dimensions. Our simulations include the backreaction of quarks on…
