We study direct photon production within a hybrid minijet-hydrodynamics framework that incorporates initial-state fluctuations and minijet-medium interactions. Using the IP-Glasma + MUSIC + UrQMD framework, and a dedicated photon emission module, we perform a comprehensive analysis of direct photon production. By including minijet effects in the hydrodynamic evolution, we examine the sensitivity of photon yields and elliptic flow to the dynamics of the quark-gluon plasma. Our results demonstrate the significant impact of hydrodynamic evolution on photon production, highlighting the essential role of minijet-medium interactions.
The main focus of the talk will be how non-equilibrium aspects of hot QCD matter (the quark–gluon plasma) produced in heavy-ion collisions affect the properties of heavy quarks.
In this talk, we will review recent efforts to probe spin–spin and spin–orbit entanglement at the upcoming Electron–Ion Collider (EIC). We will also discuss its connections to nucleon structure and high-energy QCD dynamics.
Multi-body QCD exhibits rich and complex phenomenology, notably in the Quark-Gluon Plasma (QGP) at high temperature, which is generated in nuclear collisions at RHIC and the LHC; and at high density, corresponding to low momentum fraction x in hadrons and nuclei, which can be probed by forward RHIC and LHC measurements and the future Electron-Ion Collider.
These lectures will explore how we study multi-body QCD by combining experiment and theory. The focus of the first two lectures is the measurement of jet quenching, the interaction of energetic quark and gluon jets with the QGP. The third lecture discusses a comprehensive analysis of the world’s jet quenching data using Bayesian Inference enhanced by Machine Learning, to quantify the structure and dynamics of the QGP. The fourth lecture turns to many-body QCD at low x, presenting a new framework for the comprehensive analysis of Deep Inelastic Scattering and hadron collider data - likewise using ML-enhanced Bayesian Inference - to search for evidence of non-linear QCD evolution and gluon saturation.
In this talk, I'll give a brief overview of the theory of probing the internal structure of the nucleon in 3D at the upcoming electron-ion collider (EIC).
