I will discuss multiplicity dependent and non-binomial efficiency corrections to higher order cumulants in heavy-ion collisions. These effects are quantitatively important and cannot be treated using the factorial moments. The most straightforward method to implement these corrections will be presented. In the second part of my talk I will discuss a novel observable that is sensitive to the...

In light of the net-proton number fluctuations recently measured by STAR in the BES program at RHIC, we discuss to what extent a critical point in the QCD phase diagram could be responsible for the observed beam energy dependence. Assuming QCD to belong to the 3d Ising model universality class, we analyze the imprint of critical fluctuations in the chiral order parameter onto the net-proton...

We present an analysis of the net-proton kurtosis and the chiral kurtosis on the crossover side near the critical point in the model of nonequilibrium chiral fluid dynamics. The chiral order parameter is propagated explicitly and coupled to an expanding fluid of quarks and gluons to describe the dynamical situation in a heavy-ion collision. We aim at disentangling two distinct sources of...

Heavy ion collision experiments search for a critical point in the phase diagram of nuclear matter by measuring non-Gaussian moments of baryon number. Universality of critical phenomena predicts that non-Gaussian moments are enhanced near a critical point.
We show that universality near a critical end point implies a characteristic relation between third- and fourth-order baryon...

In heavy-ion physics, measurements of short-lived hadronic resonances allow the properties of the hadronic phase of the collision to be studied. In addition, resonances can be used along with stable hadrons to study parton energy loss in the quark-gluon plasma and the mechanisms that shape hadron $p_{\mathrm{T}}$ spectra at intermediate transverse momenta. Resonance measurements in small...

The transverse momentum ($p_{T}$) spectra have been studied with different collision systems and in a wide range of collision energies.
They have provided much information such as kinetic and chemical freeze-out temperatures of the medium created by the heavy ion collisions by comparing to the hydrodynamical and statistical thermal models, respectively.
In order to get intrinsic properties,...

We analyze hadrochemical freeze-out in central collisions of mass 200 nuclei, at AGS, SPS and LHC energies. Ideally, the hadronic multiplicities are the outcome of QCD hadronization, which creates them in Grand Canonical(GC) equilibrium of species essentially due to phase space dominance. The GC analysis performed in the Statistical Hadronization Model(SHM) thus ideally reveals points along...

Proton-proton (pp) collisions have been used extensively as a reference for the study of interactions of larger colliding systems at the LHC.
Recent measurements performed in high-multiplicity pp and proton-lead (p-Pb) collisions have shown features that are reminiscent of those observed in lead-lead (Pb-Pb) collisions.
In this context, the study of identified particle spectra and yields as...

Transport simulations like UrQMD allow to study the time evolution of a
pure non-equilibrated Hagedorn state gas towards a thermally
equilibrated Hadron Resonance Gas by using dynamics, which unlike
strings, fully respect detailed balance. In principle, our prescription
offers a genuine understanding for multi-hadronic collisions.
Propagation, repopulation, rescatterings and decays of Hagedorn...

We reconsider the possibility that high baryon densities may be achievable in the so-called fragmentation regions achievable at RHIC and LHC using the most recent knowledge of baryon stopping and energy deposition in the central rapidity region. We find that baryon densities exceeding ten times normal nuclear matter are feasible. The entropy per baryon are low enough so as to be relevant for...
