Abstract:

Fractals and different background states (mixed, random, distributed by Gauss, power and exponent laws) are analyzed by SePaC method aimed at search for and reconstruction of fractal structures. It is shown that part of background events is reconstructed as fractals. Distributions of different events by the fractal dimension is studied. It is found that these distributions for fractals and background events are different. Some characteristics describing features of fractal structures are presented and their comparison for fractals and background events is performed. Criteria for background suppression are suggested and analysis results are presented. It is shown that application of the criteria separately changes the background event distribution by the fractal dimension and their combination results in noticeable background suppression.

The investigation has been performed at the Veksler and Baldin Laboratory of High Energy Physics.
