Recent results on event-by-event fluctuations in ALICE at the LHC / Behera, Nirbhay Kumar (Indian Inst. Tech., Mumbai) /for the ALICE collaboration
Non-statistical event-by-event fluctuations in relativistic heavy-ion collisions have been proposed as a probe of the phase transition of hadronic matter to a deconfined phase of quarks and gluons, the so-called Quark-Gluon Plasma. In a thermodynamical picture of the strongly interacting system formed in heavy-ion collisions, the dynamical fluctuations of net-charge, fluctuations of the mean transverse momentum, mean multiplicity and balance functions are related to the fundamental properties of the system, hence they may reveal information about the QCD phase transition.

Recent results on event-by-event fluctuations in ALICE at the LHC / Jena, Satyajit (Texas U., Houston) /ALICE
Non-statistical event-by-event fluctuations in relativistic heavy-ion collisions have been proposed as a probe of phase instabilities near the QCD phase transition. In a thermodynamical picture of the strongly interacting system formed in heavy-ion collisions, the fluctuations of the mean transverse momentum, mean multiplicity fluctuations, the balance function, higher moments of net-particle multiplicity distributions, etc., are related to the fundamental properties of the system, hence they may reveal information about the QCD phase transition.

Net-charge fluctuations and balance functions at the LHC / Weber, Michael (Houston U.) /for the ALICE collaboration
The measurement of event-by-event fluctuations and charge-dependent particle correlations are used to study properties of nuclear matter at high temperatures as produced in ultrarelativistic heavy-ion collisions. We present results for event-by-event net-charge fluctuations and charge balance functions in $\Delta\eta$ and $\Delta\phi$ in Pb-Pb collisions at $\sqrt{s_{NN}}$= 2.76$ TeV..

Probing the dynamical evolution of QGP using charge-dependent correlations and fluctuations at CMS / Chatterjee, Sayan (Indian Inst. Tech., Madras) /CMS Collaboration
We present the first studies of net-charge fluctuations and charge-balance functions using the broad rapidity coverage of the CMS experiment. These types of event-by-event fluctuations are a powerful tool to characterize the thermodynamic properties of the quark-gluon plasma (QGP). [...]

First event-by-event fluctuation studies in Pb-Pb collisions at LHC energy by the ALICE experiment / Jena, Satyajit (Indian Inst. Tech., Mumbai) /for the ALICE collaboration
The presence of the phase transition can manifest itself by the characteristic behavior of several observables which may vary dramatically from one event to the other. Thus, the study of various conserved quantities on an event-by-event basis offers the possibility to study the phase transition and the nature of high density matter. [...]

Measurements of net-charge fluctuations across various colliding systems with ALICE / Khan, Shaista (Aligarh Muslim U.)
Event-by-event fluctuations of conserved quantities such as electric charge, baryon number, and strangeness in ultrarelativistic heavy-ion collisions provide insight into the properties of the quark-gluon plasma and the QCD phase diagram. The net-charge fluctuations in finite phase space are usually studied using the $\nu_{dyn}[+,-]$ observable, which is robust against the detection efficiency losses. [...]

Probing thermal nature of matter formed at RHIC via fluctuations / Gupta, Sourendu (Tata Inst.) ; Mallick, Debasish (NISER, Jatni) ; Mishra, Dipak K (Bhabha Atomic Res. Ctr.) ; Mohanty, Bedangadas (NISER, Jatni ; CERN) ; Xu, Nu (CCNU, Wuhan, Inst. Part. Phys. ; Hua-Zhong Normal U., LQLP ; Lanzhou, Inst. Modern Phys.)
Arguments for thermalization of the QCD matter created in high-energy nuclear collisions has dominantly come from the agreement of the measured yields of produced hadrons with those from statistical thermal models. Ideally for a thermalized system, in addition to mean, the higher orders of the moments of the multiplicity distribution of produced particles should also show agreement with thermal models. [...]

Event-by-Event correlations and fluctuations with strongly intensive quantities in heavy-ion and / Sputowska, Iwona Anna (Cracow, INP) /ALICE Collaboration
This paper presents a short overview of event-by-event correlations and fluctuations analysis with strongly intensive quantities measured by ALICE at LHC in pp, p--Pb, Xe--Xe, and Pb--Pb collisions in the overall energy regime ranging from $\sqrt{s_{\rm NN}}=0.9$ up to 13~TeV. The evolution of the forward-backward strongly intensive quantity $\Sigma$ is analyzed as a function of the distance between forward and backward pseudorapidity intervals ($\eta$ gap), the centrality of the collision, and the width of the centrality bin.

Correlations and fluctuations studied with ALICE / Weber, Michael (Houston U.) /for the ALICE collaboration
The measurement of particle correlations and event-by-event fluctuations of physical observables allows to study a large variety of properties of the matter produced in ultra relativistic heavy-ion collisions. We will present results for two-particle correlations, mean transverse momentum fluctuations, and net charge fluctuations in Pb-Pb collisions at 2.76 TeV..

Event-by-event physics in ALICE / Zampolli, C (Enrico Fermi Ctr., Rome ; INFN, Bologna) /ALICE
Event-by-Event (E-by-E) fluctuations are one of the main dynamical probes of the phase transition from ordinary hadronic matter to a plasma of quarks and gluons, which is expected to occur in ultra-relativistic heavy-ion collisions. In this article, the results of a study concerning the observability of E-by-E fluctuations for the ALICE experiment at the LHC collider at CERN is presented. [...]
