    To date, the problem of cybersecurity is topical. Every day, each of us is faced with the need to use information technology, beginning with the placement of personal information on the Internet, to the use of ATMs, bank accounts, etc. Hence the question arises whether this problem is controlled by national legislation and whether our information is well protected

    A new method for the experimental study of topological effects in the quark-gluon plasma

    A new method is presented for the quantitative measurement of charge separation about the reaction plane. A correlation function is obtained whose shape is concave when there is a net separation of positive and negative charges. Correlations not specifically associated with charge, from flow, jets and momentum conservation, do not influence the shape or magnitude of the correlation function. Detailed simulations are used to demonstrate the effectiveness of the method for the quantitative measurement of charge separation. Such measurements are a pre-requisite to the investigation of topological charge effects in the QGP as derived from the "strong CP\cal{CP} problem".Comment: Six pages 13 figures.

    Glauber-based evaluations of the odd moments of the initial eccentricity relative to the even order participant planes

    Full text link
    Monte Carlo simulations are used to compute the centrality dependence of the odd moments of the initial eccentricity ϵn+1\epsilon_{n+1}, relative to the even order (n) participant planes Ψn\Psi^*_n in Au+Au collisions. The results obtained for two models of the eccentricity -- the Glauber and the factorized Kharzeev-Levin-Nardi (fKLN) models -- indicate magnitudes which are essentially zero. They suggest that a possible correlation between the orientations of the the odd and even participant planes (Ψn+1\Psi^*_{n+1} and Ψn\Psi^*_n respectively), do not have a significant influence on the calculated eccentricities. An experimental verification test for correlations between the orientations of the the odd and even participant planes is also proposed.Comment: 3 pages, 1 figure. Version accepted for publicatio
