Photoproduction of the $f_2(1270)$ meson using the CLAS detector
/ CLAS Collaboration
The quark structure of the $f_2(1270)$ meson has, for many years, been assumed to be a pure quark-antiquark ($q\bar{q}$) resonance with quantum numbers $J^{PC} = 2^{++}$. Recently, it was proposed that the $f_2(1270)$ is a molecular state made from the attractive interaction of two $\rho$-mesons. [...]

Heavy quark diffusion in an overoccupied gluon plasma
/ Boguslavski, K. (Vienna, Tech. U.) ; Kurkela, A. (CERN ; Stavanger U.) ; Lappi, T. (Jyvaskyla U. ; Helsinki U.) ; Peuron, J. (ECT, Trento ; Fond. Bruno Kessler, Trento)
We extract the heavy-quark diffusion coefficient \kappa and the resulting momentum broadening in a far-from-equilibrium non-Abelian plasma. We find several features in the time dependence of the momentum broadening: a short initial rapid growth of , followed by linear growth with time due to Langevin-type dynamics and damped oscillations around this growth at the plasmon frequency. [...]

Heavy quark momentum diffusion coefficient in 3D gluon plasma
/ Boguslavski, K. (Vienna, Tech. U.) ; Kurkela, A. (Jyvaskyla U. ; CERN) ; Lappi, T. (Stavanger U. ; Helsinki U.) ; Peuron, J. (ECT, Trento)
We study the heavy-quark momentum diffusion coefficient in far from equilibrium gluon plasma in a self-similar regime using real-time lattice techniques. We use 3 methods for the extraction: an unequal time electric field 2-point correlator integrated over the time difference, a spectral reconstruction (SR) method based on the measured equal time electric field correlator and a kinetic theory (KT) formula.

Pion and Kaon Structure at the Electron-Ion Collider
/ Aguilar, Arlene C. (Campinas State U.) ; Ahmed, Zafir (Regina U.) ; Aidala, Christine (Michigan U.) ; Ali, Salina (Catholic U.) ; Andrieux, Vincent (Illinois U., Urbana (main) ; CERN) ; Arrington, John (Argonne (main)) ; Bashir, Adnan (IFM-UMSNH, Michoacan) ; Berdnikov, Vladimir (Catholic U.) ; Binosi, Daniele (ECT, Trento ; Fond. Bruno Kessler, Trento) ; Chang, Lei (Nankai U.) et al.
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 the roughly 1 GeV mass-scale that characterizes atomic nuclei appear; why does it have the observed value; and, enigmatically, why are the composite Nambu-Goldstone (NG) bosons in quantum chromodynamics (QCD) abnormally light in comparison? In this perspective, we provide an analysis of the mass budget of the pion and proton in QCD; discuss the special role of the kaon, which lies near the boundary between dominance of strong and Higgs mass-generation mechanisms; and explain the need for a coherent effort in QCD phenomenology and continuum calculations, in exa-scale computing as provided by lattice QCD, and in experiments to make progress in understanding the origins of hadron masses and the distribution of that mass within them.

Highly occupied gauge theories in 2+1 dimensions: self-similar attractor
/ Boguslavski, K. (Vienna, Tech. U. ; Jyvaskyla U.) ; Kurkela, A. (CERN ; Stavanger U.) ; Lappi, T. (Jyvaskyla U. ; Helsinki U.) ; Peuron, J. (ECT, Trento ; Fond. Bruno Kessler, Trento)
Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar field in the adjoint representation. We show that irrespective of the details of the initial condition, the far-from-equilibrium evolution of these highly occupied systems approaches a unique universal attractor at high momenta that is the same for the gauge and scalar sectors.

Probing spectral properties of the QGP with real-time lattice simulations
/ Boguslavski, Kirill (Jyvaskyla U.) ; Kurkela, Aleksi (CERN ; Stavanger U.) ; Lappi, Tuomas (Helsinki U. ; Jyvaskyla U.) ; Peuron, Jarkko (ECT, Trento ; Fond. Bruno Kessler, Trento)
We present a new method to obtain spectral properties of a non-Abelian gauge theory in the region where occupation numbers are high. The method to measure the (single-particle) spectral function is based on linear response theory and classical-statistical lattice simulations. [...]

Report from Working Group 4 : Opportunities in Flavour Physics at the HL-LHC and HE-LHC
/ Cerri, A. (Sussex U.) ; Gligorov, V.V. (Paris U., VI-VII) ; Malvezzi, S. (INFN, Milan Bicocca) ; Martin Camalich, J. (Laguna U., Tenerife ; IAC, La Laguna) ; Zupan, J. (Cincinnati U.) ; Akar, S.

Motivated by the success of the flavour physics programme carried out over the last decade at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High-Luminosity and High-Energy upgrades in this domain of physics. We document the extraordinary breadth of the HL/HE-LHC programme enabled by a putative Upgrade II of the dedicated flavour physics experiment LHCb and the evolution of the established flavour physics role of the ATLAS and CMS general purpose experiments.

Status of head-on beam-beam compensation in RHIC

In polarized proton operation, the performance of the Relativistic Heavy Ion Collider (RHIC) is limited by the head-on beam-beam effect. To overcome this limitation, two electron lenses are under commissioning. [...]
