چکیده

The measurement of anisotropic flow in heavy ion collisions gives insight into the equation of state of the matter formed in the collision. Several methods are available for measuring anisotropic flow. However, methods based on two-particle correlations do not reproduce the flow signal if nonflow is present. Methods based on multi-particle correlations do. A new reaction plane estimate is presented based on the Lee-Yang zeroes method, that enables an unbiased analysis of e.g. jets or charm versus the reaction plane.

Nuclear Collective Flow from the Method of Lee-Yang Zeroes

This report presents the first analysis of collective flow with the new method of Lee-Yang zeroes [1]. So far in the SIS energy range all directed and elliptic flow analyses were performed using standard procedures. In these methods, based either on the reaction plane reconstruction or on two-particle correlations one assumes that correlations between particles are only due to flow. This shortc...

Lee-yang Zeroes and Logarithmic Corrections in the Φ

The leading mean-field critical behaviour of φ 4 4-theory is modified by multiplicative logarithmic corrections. We analyse these corrections both analytically and numerically. In particular we present a finite-size scaling theory for the Lee-Yang zeroes and temperature zeroes, both of which exhibit logarithmic corrections. On lattices from size 8 4 to 24 4 , Monte-Carlo cluster methods and mul...

Density of the Fisher zeroes for the Ising model

In the analyses of lattice models in statistical mechanics such as the Ising model, the partition function is often expressed in the form of a polynomial in variables such as the external magnetic field and/or the temperature. Since properties of a polynomial are completely determined by its roots, a knowledge of the zeroes of the partition function yields all thermodynamic properties of the sy...

Anisotropic flow from Lee–Yang zeroes: a practical guide

where 〈. . .〉 here denotes an average over many particles and events. In particular, elliptic flow v2 is recognized as a sensitive probe of thermalization at RHIC [2]. While anisotropic flow is by definition a collective effect that involves many particles, it has mostly been analyzed using methods based either on a study of twoparticle correlations [3–5] or on the cumulants of correlations bet...
