Machine Learning-Assisted Measurement of Lepton-Jet Azimuthal Angular Asymmetries in Deep-Inelastic Scattering at HERA / H1 Collaboration
In deep-inelastic positron-proton scattering, the lepton-jet azimuthal angular asymmetry is measured using data collected with the H1 detector at HERA. [...]

The v1/33/v1/22 ratio in PbAu collisions at sNN= 17.3 GeV: a hint of a hydrodynamic behavior / CERES NA45 Collaboration
The Fourier harmonics, v2 and v3 of negative pions are measured at center-of-mass energy per nucleon pair of sNN= 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 pT 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 s=319 GeV, using data recorded between the years 2003 and 2007 with an integrated luminosity of 351 pb1. 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 τb1 in neutral-current deep-inelastic electron-proton scattering (DIS). The observable τb1 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 π0, ω, KS, K, and ϕ 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..
