Collectivity in Small Systems
- Alexander Philipp Kalweit (CERN)
Strangeness production has long been considered a golden observable to characterize the chemical composition of the deconfined state of matter produced in heavy ion collisions. One of the key results of the LHC Run 1 was the observation of an enhanced production of strange particles in high multiplicity pp and p-Pb collisions at 7 and 5.02 TeV, respectively. In addition, the multiplicity...
Proton-nucleus collisions at relativistic energy, traditionally regarded as control measurements for heavy ion collisions, are now capturing the attention due to the recent experimental observations at RHIC and LHC that indicate the formation of quark-gluon plasma even in these small systems. In the early stage of relativistic heavy ion collisions extremely intense magnetic fields, with a...
ALICE has performed several measurements aimed at understanding the heavy-ion-like patterns observed in small collision systems. New approaches can be helpful to clarify particle production mechanisms in pp collisions, as well as the similarities observed among the systems created in pp, p-A and A-A collisions.
In this talk we report on charged particle transverse momentum distributions as a...
Measurements of bottomonium production are reported for the $\Upsilon(1S)$, $\Upsilon(2S)$, and $\Upsilon(3S)$ mesons in pp, pPb and PbPb collisions at 5.02 TeV. The analysis was performed as a function of rapidity and transverse momentum. In addition, the dependence on the event activity and collision centrality is studied in pPb and PbPb collisions, respectively. New results of the upsilon...
Heavy quarks (charm and beauty) are effective probes to test perturbative QCD-based calculations in pp collisions and to study cold nuclear matter (CNM) effects such as gluon saturation, shadowing, kT broadening and energy loss in CNM in p-Pb collisions. In addition, the positive elliptic flow ($v_2$) of open heavy-flavour particles observed in semi-central Pb-Pb collisions at LHC energies...
