Observations of possible collective effects in high-multiplicity
$p$$+$$p$ collisions at the LHC and in $p$$+$Pb and $d$$+$Au
collisions at the LHC and RHIC challenge our understanding of the
requirements for quark-gluon plasma formation. To further
investigate this, PHENIX recorded high statistics $p$$+$$p$ and
$p$$+$Au data sets in 2015. In both cases, high-multiplicity
triggers were...

We have investigated the hypothesis that small collision systems (p+A, d+A, 3He+A) at RHIC and the LHC form small droplets of nearly inviscid quark-gluon plasma within the context of hydrodynamic models (Phys.Rev.Lett. 113 (2014) 11, 112301) and with an extension of the AMPT model
(arXiv:1501.06880). We explore the constraints on such pictures and the geometric scaling by varying the...

The ATLAS measurement of azimuthal correlations between particle pairs at large pseudorapidity separation in pp collisions at sqrt(s)=13 TeV are presented. The data were collected using a combination of the minimum-bias and high track-multiplicity triggers. A detailed study of the dependence of two-particle correlations on the charged particle multiplicity, transverse momentum of the pair...

Observation of a long-range, near-side, two-particle correlation (known as the “Ridge”) in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small collision systems. While extensive studies of this long-range correlation phenomenon in pPb collisions have revealed its collective properties, the nature of the ridge in pp collisions still...

Recent measurements performed in high-multiplicity proton-proton (pp) and proton-lead (p-Pb) collisions have shown features that are reminiscent of those observed in lead-lead (Pb-Pb) collisions.
These observations warrant a comprehensive measurement of the production of identified particles.
We report on the production of
$K_{\rm S}^{0},~\Lambda,~\bar\Lambda$, $\Xi^{-}$, $\bar\Xi^{+}$,...

We investigate effects of causal hydrodynamic fluctuation on dynamics of the quark gluon plasma (QGP) in Bjorken expansion in high-energy nuclear collisions. The space-time evolution of the QGP can be well described by relativistic hydrodynamics. In the recent hydrodynamic analyses, effects of event-by-event (e-by-e) initial fluctuation on final flow observables have been focused. Moreover, it...

I will discuss recent experimental results in proton-proton, proton-lead and deuteron-gold collisions at the LHC and RHIC, and explain how they influence our understanding of non-perturbative QCD at high energy density. Several ideas that may help to disentangle between initial state effects, e.g., the color glass condensate, and final state effects such as hydrodynamics or transport models...
