Parallel Session - Small systems III
- Norbert Herrmann (Univ. Heidelberg)
The large samples of high-quality data taken in pp collisions at $\sqrt{s} = 5$, 7 and 13 TeV and in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV at the LHC with the ALICE detector allows a systematic study of light (anti-)nuclei production to be performed in these collision systems. The excellent performance of the Inner Tracking System, Time-Projection Chamber and Time-Of-Flight...
The evolution of a heavy-ion collision is typically understood as a process that transmutes the initial geometry of the system into the final momentum distribution of observed hadrons, which can be described via a cumulant expansion of the initial distribution of energy density and is represented at leading order as the well-known eccentricity scaling of anisotropic flow.
We extend this...
The study of light flavour (u,d,s) hadron production plays an important role in understanding the dynamics of the strongly-interacting system created in nucleus-nucleus collisions, the
Quark-Gluon Plasma (QGP). Historically, it has been assumed that no QGP is formed in small collision systems, but this paradigm is challenged by the observation of collective-like behaviour and strangeness...
Collisions of small systems exhibit evidence of collective behavior through various flow type measurements, which suggests that quark gluon plasma could be produced in these collisions. If so, there could also be evidence for energy loss in the plasma, which would present itself in the spectra of hadrons. PHENIX has studied the nuclear modification factor $R_{AB}$ of various hadron species at...
Pythia8 is the only general purpose event generator able to produce
fully exclusive hadronic final states in collisions involving heavy
ions. This is done by carefully stacking individual parton-level
nucleon-nucleon collisions together according to the so-called
Angantyr model. The sub-events are produced using the full Pythia8
machinery with initial and final state parton showers and...
