Cumulants of Net-charge Distribution from Particle–Antiparticle Sources

Blind separation of sources using higher-order cumulants

In this paper, we propose a novel method of blind signal separation using a new performance criterion with nonlinear separating functions, and derive an adaptive algorithm. The criterion consists of nonlinear mappings of output signals and their cumulants for independence of the signals. We show that our method requires a weak condition for stable separation through the ODE analysis. Simulation...

First Result of Net-Charge Jet-Correlations from STAR

We presented results on azimuthal correlation of net-charge with high pT trigger particles. It is found that the net-charge correlation shape is similar to that of total-charge. On the near-side, the net-charge and total-charge pT spectra have similar shape and both are harder than the inclusives. On the away-side, the correlated spectra are not much harder than the inclusives, and the net-char...

Numerical Investigation of the Non-Uniformity of the Electric Field Distribution by Injection of Net Electron Charge in TE CO2 Laser

In this report, the distribution and deviation of electric field in the active medium of the TE CO2 laser has been investigated due to the injection of net electron charge beam as a plasma generator. Some parameters of system have been considered, such as density and mean-free-path of injected charge beam. The electric potential and electric field distribution have been simulated by solving the...

Sources lndentification : A Solution Based on the Cumulants

In a great number of situations (array processing, seismic sounding...), the signal received on an array of sensors is the sum of several contributions (sources). In general, it is realistic to assume that the sources emit independent stochastic signals. In this case, several methods using the second order statistic of the signal have been developed in order to detect the number of sources and ...
