Relativistic collisions of light on heavy ions (p + Au at $$\sqrt{s}=7.7$$s=7.7 GeV, p + Au , d + Au ,$$^3$$3He + Au at $$\sqrt{s}=62.4$$s=62.4 GeV and 200 GeV and p + Pb ,$$^3$$3He + Pb at $$\sqrt{s}=5.02$$s=5.02 TeV) are simulated using “superSONIC”, a model that includes pre-equilibrium flow, viscous hydrodynamics and a hadronic cascade afterburner. Even though these systems have strong gradients and only consist of at most a few tens of charged particles per unit rapidity, one finds… 
Exploring new small system geometries in heavy ion collisions
Relativistic heavy ion collisions produce nuclei-sized droplets of quark-gluon plasma whose expansion is well described by viscous hydrodynamic calculations. Over the past half decade, this formalism
Testing hydrodynamic descriptions of p+p collisions at $$\sqrt{s}=7$$s=7 TeV
In high-energy collisions of heavy ions, experimental findings of collective flow are customarily associated with the presence of a thermalized medium expanding according to the laws of
Investigations of $p$+Pb Collisions at Perturbative and Non-Perturbative QCD Scales
High energy nuclear collisions manifest a variety of interesting phenomena over a broad range of energy scales. Many of these phenomena are related to the formation of a hot and dense state of
Measurement of long-range angular correlations and azimuthal anisotropies in high-multiplicity p plus Au collisions at root S-NN=200 GeV
We present the first measurements of long-range angular correlations and the transverse momentum dependence of elliptic flow $v_2$ in high-multiplicity $p$$+$Au collisions at $\sqrt{s_{_{NN}}}=200$
Collectivity in Small QCD Systems
Features of collectivity observed in high energy A+A collision systems at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) imply a strongly coupled quark gluon plasma
Squeezed back-to-back correlations of K +K −in d + Au collisions at ${\sqrt{{s_{NN}}}}$=200 GeV and Au + Au collisions at ${\sqrt{{s_{NN}}}}$ = 62.4 GeV
We investigate the squeezed back-to-back correlations (BBC) of $K^+$$K^-$, caused by the mass modification of the particle in the dense medium formed in d+Au collisions at $\sqrt{s_{NN}}=200$ GeV and
Azimuthal anisotropy relative to the participant plane from a multiphase transport model in central p + Au , d + Au , and He 3 + Au collisions at s N N = 200 GeV
Recent data from p+p and p+Pb collisions at the Large Hadron Collider (LHC), and d+Au and $^3$He+Au collisions at the Relativistic Heavy Ion Collider (RHIC) reveal patterns that---when observed in
Fluctuations in ultra-relativistic heavy ion collisions
Fluctuations are one of the main probes of the physics of the new state of hot and dense nuclear matter called the Quark Gluon Plasma (QGP) which is created in the ultra-relativistic heavy ion
Measurements of second-harmonic Fourier coefficients from azimuthal anisotropies in $p$$+$$p$, $p$$+$Au, $d$$+$Au, and $^3$He$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV
Recently, the PHENIX Collaboration has published second- and third-harmonic Fourier coefficients $v_2$ and $v_3$ for midrapidity ($|\eta|<0.35$) charged hadrons in 0\%--5\% central $p$$+$Au,
Recent results on collective effects in small systems from PHENIX at RHIC
Collisions of simple systems, such as $p$+$p$, or $p$+Nucleus have been used as benchmarks for our understanding of heavy ion collsions, since it was assumed they would be free of the effects from


Particle spectra and HBT radii for simulated central nuclear collisions of C + C, Al + Al, Cu + Cu, Au + Au, and Pb + Pb from $$\sqrt{s}=62.4$$s=62.4–$$2760$$2760 GeV
We study the temperature profile, pion spectra, and HBT radii in central, symmetric, and boost-invariant nuclear collisions, using a super hybrid model for heavy-ion collisions (SONIC), combining
Exploiting intrinsic triangular geometry in relativistic (3)He+Au collisions to disentangle medium properties.
Using a Monte Carlo Glauber simulation, it is found that a ^{3}He or triton projectile, with a realistic wave function description, induces a significant intrinsic triangular shape to the initial medium.
Determining Fundamental Properties of Matter Created in Ultrarelativistic Heavy-Ion Collisions
Posterior distributions for physical parameters describing relativistic heavy-ion collisions, such as the viscosity of the quark-gluon plasma, are extracted through a comparison of hydrodynamic-based
Eccentric protons? Sensitivity of flow to system size and shape in p+p, p+Pb, and Pb+Pb collisions.
It is argued that the measured vn data and HBT radii strongly constrain the shapes of initial parton distributions across system sizes that would be compatible with a flow interpretation in p+Pb collisions.
Collective flow in p-Pb and d-Pb collisions at TeV energies
We apply the hydrodynamic model for the dynamics of matter created in p-Pb collisions at 4.4TeV and d-Pb collisions at 3.11TeV. The fluctuating initial conditions are calculated in the Glauber
Fluctuating glasma initial conditions and flow in heavy ion collisions.
We compute initial conditions in heavy ion collisions within the color glass condensate framework by combining the impact parameter dependent saturation model with the classical Yang-Mills
Structure and dynamics of few-nucleon systems
Few-nucleon physics is a field rich with high-quality experimental data and possibilities for accurate calculations of strongly correlated quantum systems. In this article the authors discuss the
Characteristics of thermalization of boost-invariant plasma from holography.
A sizable anisotropy in the energy-momentum tensor at thermalization is observed, which suggests that effective thermalization in heavy-ion collisions may occur significantly earlier than true thermalization.
Early time dynamics in heavy-ion collisions from AdS/CFT correspondence
We study the matter produced in heavy-ion collisions, assuming that this matter is strongly interacting and employing AdS/CFT correspondence to investigate its dynamics. At late proper times τ we
