Over the past decades relativistic heavy-ion collision experiments have revealed exciting properties of nuclear matter under extreme conditions. While a first principle theoretical description of the space-time dynamics of a heavy-ion collision remains an outstanding challenge, significant progress has been achieved and I will discuss recent theoretical developments in this direction....

Anomalous chiral transport processes, with the notable example of Chiral Magnetic Effect (CME) and Chiral Magnetic Wave (CMW), are remarkable phenomena that manifest microscopic quantum anomaly of chiral fermions in a macroscopic many-body setting. Significant progress has been achieved both in their theoretical understanding and in their experimental search. In this talk, an elementary...

The proton radius puzzle is the difference between the radius of the proton as measured with electron scattering and atomic hydrogen spectroscopy, and that measured in muonic hydrogen. In 2010, the CREMA Collaboration published their measurement of the proton radius $R_p=0.8409(4)$ fm, which was made by studying the Lamb shift in muonic hydrogen. Although ten times more precise than the...

Recent progress in lattice QCD calculations of hadron structure will be reviewed, with an emphasis on nucleon structure. A wide range of nucleon observables are being studied in modern lattice calculations. The axial charge and electromagnetic form factors are well known from experiment, and serve as benchmarks for lattice calculations. Sigma terms and tensor and scalar charges are relevant...

The quark mass and strong coupling constant parameters of the QCD Lagrangian are free parameters in the Standard Model and can only be determined by comparison of theory and experiment.
Lattice QCD gives us direct access to the QCD Lagrangian and so is well-suited to the determination of these parameters. I will review the methods used to date, the results obtained and prospects for future...

The transverse-momentum-dependent (TMD) factorization has been applied to make theoretical predictions for many TMD processes with a large enough momentum scale. In this framework, transverse momenta of both perturbative and nonperturbative origin are incorporated. It is very non-trivial to make the transition between these two types of dynamics, especially when the hard momentum scale is...

The COMPASS experiment (SPS, CERN) covers a broad range of physics aspects in the field of hadron structure and spectroscopy. Particular focus is given to the exploration of the transverse spin structure of the nucleon via the study of spin (in)dependent azimuthal asymmetries measured in semi-inclusive deep inelastic scattering (SIDIS) and Drell-Yan (DY). Within QCD parton model approach,...

A number of states containing heavy quarks have been observed in recent years by many experiments. Their properties are, at best, difficult to reconcile with a conventional meson interpretation; some of them are manifestly exotic.
I will present recent results from LHC aimed at understanding the nature of these puzzling states

We review the present landscape of heavy-quarkonium theory, its tests
by worldwide collider and fixed-target experiments, and the future
perspectives offered by the LHC. Special emphasis is placed on the
effective quantum field theory of nonrelativistic QCD (NRQCD), endowed
with the factorization theorem conjectured by Bodwin, Braaten, and Lepage,
which arguably constitutes the most...

The recently completed NSAC Long Range Plan has recommended an exciting 10+ years of physics program to be conducted in campaigns of critical detector and machine upgrades of the CEBAF and RHIC. Both communities of scientists involved in RHIC and JLab12 programs are expected to combine forces to exploit the exciting opportunities provided by a future Election Ion Collider (EIC) to be built at...

Parton distribution functions in the small-x limit have long been known to be dominated by gluon bremsstrahlung produced in the BFKL and BK / JIMWLK evolution mechanisms. This small-x gluon cascade generates high color-charge densities, leading to the effective semi-classical theory known as the color-glass condensate (CGC). While this unpolarized small-x evolution has been thoroughly studied,...

Experimental tests of QCD through its predictions for the strange quark content of the proton have been drastically restricted by our lack of knowledge of the violation of charge symmetry (CSV). We find unexpectedly tiny CSV in the proton's electromagnetic form factors by performing the first extraction of these quantities based on an analysis of lattice QCD data. The resulting values are an...

Hadronic physics has been immensely enriched in the past 14 years, with the addition of dozens of presumptive tetraquark and pentaquark states that have been discovered primarily in the charmonium and bottomonium sectors. Every year since 2003 has brought fresh discoveries, so this talk will start with a short tour of the new states and how the field stands at this moment. Then we will tour...

Recent simulations suggest the existence of a very light singlet scalar
in QCD-like theories that may be lying just outside the conformal window.
Assuming that the lightness of this scalar can be explained by an
approximate dilatation symmetry, we develop an effective field theory
framework for both the pions and this light scalar, the "dilatonic meson."
We argue that a power counting...

Beam-target double spin asymmetries, beam single-spin asymmetries, and target single-spin asymmetries in exclusive $\pi^+$ and $\pi^0$ electroproduction were obtained from scattering of 1.6 to 6 GeV longitudinally polarized electrons from longitudinally polarized protons using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. The kinematic range covered is final state invariant...
