Why quarks cannot be separated far enough to be observed in isolation remains a major unresolved question in hadronic structure: What are the types and strengths of the interactions that keep the colorful, asymptotically free, partons of short distance, high energy perturbative QCD confined inside colorless entities like mesons and baryons? One step towards the answer is the study of quark-gluon ( ... More

Despite the successes of the Standard Model of particle physics, it remains a challenge to understand the dynamics of the strong interaction among quarks and gluons. At small distance scales or at high energies, the underlying theory, the Quantum Chromodynamics (QCD), is well tested and understood. Our understanding of the strong interaction deteriorates dramatically at larger distances scales suc ... More

Collinear distributions such as PDFs and fragmentation functions (FFs) have long been constrained by independent global QCD analyses. However, it is well known that these functions are intimately related across various scattering processes used in global fits, particularly in the polarized sector. Recently, the JAM collaboration performed the first simultaneous analysis of spin-dependent PDFs and ... More

Exciting new measurements have produced strong evidence for small quark-gluon plasma droplets produced in collisions of protons and small nuclei on large nuclei as well as in proton on proton collisions at RHIC and the LHC. We detail a subset of the most exciting results and discuss the different theoretical interpretations. We highlight the broader physics implications of these observations.

The advent of high intensity hadronic physics experiments has lead to many advances in our understanding of hadronic states, and has raised many questions and new possibilities along the way. One particularly exciting question is how gluonic degrees of freedom contribute to the structure of hadrons. In the meson sector, “hybrid” states with gluonic contributions may have quantum numbers which ... More

Hot, dense QCD matter has been shown to have some very remarkable properties. Its vanishingly small shear viscosity to entropy density ratio means that it flows essentially without internal friction. It is also very opaque to transiting strongly interacting particles, dispersing the deposited energy rather efficiently. It remains a mystery, though, how this plasma can emerge from the cold, dense ... More

The internal structure of the proton is the result of the strong force, which is by governed Quantum-Chromo-Dynamics (QCD). Experimentally, the internal structure of the proton has been studied extensively through electromagnetic interaction using electron an muon beams. As a result we have precise information about the proton’s charge radius, its electromagnetic elastic and transition form fact ... More

In this talk, I will review recent progress in lattice-QCD calculations of hadron structure with an emphasis on nucleon structure. A wide range of nucleon observables are being studied in modern lattice calculations, and important progress has been made at physical pion mass, including the spin decomposition of the nucleon and the Bjorken-$x$ dependence of hadron structure. Challenges and pe ... More

Elastic scattering of electrons (or positrons) on the proton (or neutron) provide information on the charge and magnetization distributions inside the nucleon. Traditionally, following the pioneering work of Hofstadter in the mid-fifties, the electric and magnetic form factors GEp and GMp of the proton have been obtained from elastic cross section data from many experiments. In the late 1990’s ... More

With the advent of advanced event generators, and a variety of theoretical advances, jet quenching has now transitioned from a discovery stage to one of systematic exploration. While calculations (or rather simulations) have become considerably extensive, there are practically no jet observables left that cannot be described by what is now referred to as the multi-stage approach. I will describe t ... More

This talk will concentrate on recent developments and the resulting current open challenges in neutrino nucleon/nucleus scattering physics across the neutrino energy spectrum. Emphasis will be placed on those aspects where hadronic physics studies can aid in meeting these challenges.

Heavy ion collisions at RHIC and the LHC are perhaps best known for events in which the nuclei collide head-on, creating a volume of hot and dense matter which then decays into very high multiplicity final states. However, large (high Z) nuclei are also intense sources of high energy photons, which can interact with the other nucleus either directly or diffractively, or with each other in a gamma ... More

We propose a novel way to search for the dark photon ($A'$), the axion-like pseudo-scalar ($a$), the dark scalar ($\phi$), and the light dark matter ($\chi$) in the Compton process, $\gamma + e^- \rightarrow A'/a/\phi + e^-$ with $A'/a/\phi$ decaying into leptons, photons, or $\chi$'s (when permitted) for the mass ranges of 1 $\leq m_{A'/a/\phi} \leq$ 100 MeV/$c^2$ and 0.5 $\leq m_{\chi} \le ...

We will discuss the up-to-date theory and review recent experimental results related to understanding the proton radius puzzle, which is the conflict between measurements of the proton radius using muons as compared to measurements using electrons. There are signs that recent electron results are coming closer to the muonic ones, but there is not yet universal agreement, and disagreement leaves o ... More

In this talk I review the current status of hadron spectroscopy in the hyperon and strange meson sectors. The possibility to improve existing database by orders of magnitude with a secondary beam of $K_L$ at JLab with the GlueX setup in Hall D will be discussed. The proposed measurements will have a broad impact on a different aspects of nuclear and particle physics including: establishment ... More

I will give an overview of the important physics questions to be addressed at the future, US-based Electron-Ion Collider (EIC). This includes the mass and spin structure of the nucleon, multi-dimensional tomography and the gluon saturation at small-x.

Much needed theoretical progress is being made to support the beam energy scan (BES) program at the Relativistic Heavy Ion Collider (RHIC) and to successfully explore nuclear matter at both low and high baryon density, determine if and where there is a QCD critical point, and whether chiral symmetry is restored and the QCD chiral anomaly can be observed in the accessible region of the phase diagra ...

The Dyson-Schwinger/Bethe-Salpeter approach provides insight into many connected problems in QCD, proving to be especially powerful in describing processes that are dominated by chiral symmetry and its dynamical breaking. Being formulated in the continuum it avoids some of the difficulties encountered on the Lattice (e.g. chiral quarks etc) at the cost of having to introduce truncations. I will ... More
