The $v^{1/3}_{3}/v^{1/2}_{2}$ ratio in PbAu collisions at $\sqrt{s_{\textrm{NN}}} = $ 17.3 GeV: a hint of a hydrodynamic behavior / CERES NA45 Collaboration
The Fourier harmonics, $v_2$ and $v_3$ of negative pions are measured at center-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}$= 17.3 GeV around midrapidity by the CERES/NA45 experiment at the CERN SPS in 0--30% central PbAu collisions with a mean centrality of 5.5%. The analysis is performed in two centrality bins as a function of the transverse momentum $\mathrm{p_{\mathrm{T}}}$ from 0.05 GeV/$c$ to more than 2 GeV/$c$. [...]

Observation and differential cross section measurement of neutral current DIS events with an empty hemisphere in the Breit frame / H1 Collaboration
The Breit frame provides a natural frame to analyze lepton-proton scattering events. In this reference frame, the parton model hard interactions between a quark and an exchanged boson defines the coordinate system such that the struck quark is back-scattered along the virtual photon momentum direction. [...]

Measurement of groomed event shape observables in deep-inelastic electron-proton scattering at HERA / H1 Collaboration
The H1 Collaboration at HERA reports the first measurement of groomed event shape observables in deep inelastic electron-proton scattering (DIS) at $\sqrt{s}=319$ GeV, using data recorded between the years 2003 and 2007 with an integrated luminosity of $351$ pb$^{-1}$. Event shapes provide incisive probes of perturbative and non-perturbative QCD. [...]

Measurement of the 1-jettiness event shape observable in deep-inelastic electron-proton scattering at HERA / H1 Collaboration
The H1 Collaboration reports the first measurement of the 1-jettiness event shape observable $\tau_1^b$ in neutral-current deep-inelastic electron-proton scattering (DIS). The observable $\tau_1^b$ is equivalent to a thrust observable defined in the Breit frame. [...]

Unbinned deep learning jet substructure measurement in high Q2ep collisions at HERA / H1 Collaboration
The radiation pattern within high energy quark- and gluon-initiated jets (jet substructure) is used extensively as a precision probe of the strong force as well as an environment for optimizing event generators with numerous applications in high energy particle and nuclear physics. Looking at electron-proton collisions is of particular interest as many of the complications present at hadron colliders are absent. [...]

PHENIX results on nuclear modification of hadron production in small and large systems / Drees, Axel (speaker)
The intermediate pT region is ideal for studying hadronization and the transition from soft to hard physics.  Quark mass and flavor are key ingredients in hadronization as well as elucidating the details of energy loss mechanisms in the hard sector.  For this reason, it is essential to study a variety of different particle species, and PHENIX is ideally-suited for many resonance decay analyses.  In this talk we present spectra and nuclear modification factors of identified particles $\pi^0$, $\omega$, $K_S$, $K^*$, and $\phi$ in p+Al, p+Au, d+Au, 3He+Au, Cu+Au, Au+Au, and U+U collisions.  Implications for hadronization and energy loss will be discussed..

Halo removal experiments with hollow electron lens in the BNL Relativistic Heavy Ion Collider / Gu, X (Brookhaven) ; Fischer, W (Brookhaven) ; Altinbas, Z (Brookhaven) ; Drees, A (Brookhaven) ; Hock, J (Brookhaven) ; Hulsart, R (Brookhaven) ; Liu, C (Brookhaven) ; Marusic, A (Brookhaven) ; Miller, T A (Brookhaven) ; Minty, M (Brookhaven) et al.
A hollow electron beam has been proposed as an active control tool to remove the beam halo from high-energy, high-current hadron or ion machines (such as the High-Luminosity Large Hadron Collider). To study the halo removal rate and assess the effect on the ion beam core, one of the two electron lenses in the Relativistic Heavy Ion Collider was changed from a Gaussian beam profile to a hollow profile.
