Title: Transverse Momentum Distribution in Heavy Ion Collision using q-Weibull Formalism

Subject: Heavy Ions ; Weibull Distribution ; Collision Dynamics ; Hadrons ; Transverse Momentum ; Particle Production ; Rangefinding ; Ionic Collisions
Description: We have implemented the Tsallis q-statistics in the Weibull model of particle production known as the q-Weibull distribution to describe the transverse-momentum (pT ) distribution of the charged hadrons at mid-rapidity measured at RHIC and LHC energies. The model describes the data remarkably well for the entire pT range measured in nucleus-nucleus and nucleon-nucleon collisions. The proposed distribution is based on the non-extensive Tsallis q-statistics which replaces the usual thermal equilibrium assumption of hydrodynamical models. The parameters of the distribution can be related to the various aspects of complex dynamics associated with such collision process.

Title: p T spectra in pp and AA collisions at RHIC and LHC energies using the Tsallis-Weibull approach
Subject: Particle Collisions ; Energy Consumption;
Description: The Tsallis q -statistics have been incorporated in the Weibull model of particle production, in the form of q -Weibull distribution, to describe the transverse momentum ( $p_{T}$ p T ) distribution of charged hadrons at mid-rapidity, measured at RHIC and LHC energies. The q -Weibull distribution is found to describe the observed $p_{T}$ p T distributions over all ranges of measured $p_{T}$ p T . Below 2.2 GeV/c, while going from peripheral to central collisions, the parameter q is found to decrease systematically towards unity, indicating an evolution from a non-equilibrated system in peripheral collisions, towards a more thermalized system in central collisions. However, the trend is reversed in the all inclusive $p_{T}$ p T regime. This can be attributed to an increase in relative contribution of hard pQCD processes in central collisions. The $\lambda$ λ -parameter is found to be associated with the mean $p_{T}$ p T or the collective expansion velocity of the produced hadrons, which shows an expected increase with centrality of collisions. The k parameter is observed to increase with the onset of hard QCD scatterings, initial fluctuations, and other processes leading to non-equilibrium conditions.

Title: Describing dynamical fluctuations and genuine correlations by Weibull regularity
Author: Nayak, Ranjit; Dash, Sadhana; Sarkisyan-Grinbaum, Edward; Tasevsky, Marek

Subject: Control Charts ; Parameterization ; Mathematical Models ; Hadrons ; Regularity ; Correlation Analysis ; Variation
Description: The Weibull parametrization of the multiplicity distribution is used to describe the multidimensional local fluctuations and genuine multiparticle correlations measured by OPAL in the large statistics $$e^{+}e^{-} \to Z^{0} \to hadrons$$ sample. The data are found to be well reproduced by the Weibull model up to higher orders. The Weibull predictions are compared to the predictions by the two other models, namely by the negative binomial and modified negative binomial distributions which mostly failed to fit the data. The Weibull regularity, which is found to reproduce the multiplicity distributions along with the genuine correlations, looks to be the optimal model to describe the multiparticle production process.
