Angular correlations in internal pair conversion of aligned heavy nuclei.
We calculate the spatial correlation of electrons and positrons emitted by internal pair conversion of Coulomb excited nuclei in heavy ion collisions. The alignment or polarization of the nucleus results in an anisotropic emission of the electron-positron pairs which is closely related to the anisotropic emission of γ-rays. However, the angular correlation in the case of internal pair conversio...

متن کاملQcd Description of Angular Correlations
We review the predictions on angular correlations and their recent experimental tests at LEP and HERA. Power behaviour of correlation functions appear for large angles and reflect the underlying fractal structure in jet evolution. Asymptotic scaling laws work rather well for the low momentum particles. For angular correlations the predictions work at least qualitatively, sometimes quantitativel...
متن کاملAngular correlations of galaxy distribution
We study the angular correlations of various galaxy catalogs (CfA1, SSRS1, Perseus-Pisces, APM Bright Galaxies and Zwicky). We find that the angular correlation exponent is γ a = 0.1 ± 0.1 rather than γ a = 0.7 as usually found by the standard correlation function ω(θ). We identify the problem in the artificial decay of ω(θ). Moreover we find that no characteristic angular scale is present in a...
متن کاملAngular and Current - Target Correlations
Correlations between charged particles in deep inelastic e + p scattering have been studied in the Breit frame with the ZEUS detector at HERA using an integrated luminosity of 6.4 pb ?1. Short-range correlations are analysed in terms of the angular separation between current-region particles within a cone centred around the virtual photon axis. Long-range correlations between the current and ta...
