Nuclear modification factor within a dynamical approach to the complex entropic index Open
This work introduces a novel approach to the nuclear deformation factor $R_{\text{AA}}$, grounded in the dynamical effects of the Quark-Gluon Plasma on parton momentum. The approach uses the Blast-Wave method combined with Tsallis Statisti…

A harmonic oscillator in nonadditive statistics and a novel transverse momentum spectrum in high-energy collisions Open
It is widely observed that particles produced in high-energy collisions follow a power-law distribution. One such power-law distribution used extensively in the phenomenological studies owes its origin to nonadditive statistics proposed by…

Emergence of Koba-Nielsen-Olsen scaling in multiplicity distributions in jets produced at the LHC Open
In this work we study the multiplicity distributions (MDs) of charged particles within jets in proton-proton collisions, which were measured by the ATLAS Collaboration in 2011, 2016 and 2019. The first dataset refers to jets with smaller t…

Emergence of KNO scaling in multiplicity distributions in jets produced at the LHC Open
In this work we study the multiplicity distributions (MDs) of charged particles within jets in proton-proton collisions, which were measured by the ATLAS collaboration in 2011, 2016 and 2019. The first data set refers to jets with lower tr…

Geometric Poisson distribution of photons produced in the ultrarelativistic hadronic collisions Open
We show that the multiplicity distribution of photons produced with enhanced void probability in inelastic proton-proton collisions at $$\sqrt{s} =$$ 900 GeV, 2.76 TeV, and 7 TeV, measured at forward rapidities by the ALICE experiment…

Some Non-Obvious Consequences of Non-Extensiveness of Entropy Open
Non-additive (or non-extensive) entropies have long been intensively studied and used in various fields of scientific research. This was due to the desire to describe the commonly observed quasi-power rather than the exponential nature of …

Signatures of deuteron synthesis on the modified combinants in nuclear collisions Open
The mechanism of deuteron production in heavy-ion collisions is shown to have a significant impact on the shape of the modified combinants of their multiplicity distribution. In light of this observation, an experimental study is proposed …

Sub-Poissonian multiplicity distributions in jets produced in hadron collisions Open
In this work we show that the proper analysis and interpretation of the experimental data on the multiplicity distributions of charged particles produced in jets measured in the ATLAS experiment at the LHC indicates their sub-Poissonian na…

Beyond the relaxation time approximation Open
The relaxation time approximation (RTA) is a well known method of describing the time evolution of a statistical ensemble by linking distributions of the variables of interest at different stages of their temporal evolution. We show that i…

Relaxation and correlation times of nonequilibrium multiparticle systems Open
Relaxation and correlation times are two parameters used frequently in\napproximate descriptions of the time development of hadronizing system from\nsome initial state towards distributions observed experimentally. Chosen to\nreproduce the…

Counting distributions from the perspective of combinants Open
We present a comprehensive insight into counting distributions from the perspective of the combinants extracted from them. In particular, we focus on cases where these combinants exhibit oscillatory behavior that can provide an invaluable …

Dynamical nonextensivity or nonextensive dynamics? Open
Dense matter is usually described using some kind of mean field theory (MFT) model based on Boltzmann–Gibbs (BG) extensive statistics. However, in many cases the conditions justifying the use of BG statistics are not fulfilled because the …

A Look at Multiplicity Distributions via Modified Combinants Open
The experimentally measured multiplicity distributions exhibit, after a closer inspection, the peculiarly enhanced void probability and the oscillatory behavior of modified combinants. We show that both these features can be used as additi…

Intriguing properties of multiplicity distributions Open
Multiplicity distributions exhibit, after closer inspection, peculiarly\nenhanced void probability and oscillatory behavior of the modified combinants.\nWe discuss the possible sources of these oscillations and their impact on our\nunderst…

The dynamics of QCD matter is often described using effective mean field (MF) models based on Boltzmann–Gibbs (BG) extensive statistics. However, such matter is normally produced in small packets and in violent collisions where the usual c…

We argue that recent high energy CERN LHC experiments on transverse momenta distributions of produced particles provide us new, so far unnoticed and not fully appreciated, information on the underlying production processes. To this end we …
