This paper discusses how the DELPHI experiment used tau lepton characteristics to search for new particles, setting limits on their existence by distinguishing signals from background noise.

Contribution

It introduces a novel approach leveraging tau lepton properties to improve the sensitivity of new particle searches at DELPHI.

Findings

Limits on new particles involving tau leptons were established.

Tau lepton topology effectively discriminates signal from background.

The method enhances search capabilities for new physics in collider experiments.

Abstract

Several new particle searches have been performed in the DELPHI experiment involving tau leptons in the resulting final state. The topology and special characteristics of the tau leptons have been used to discriminate the signal from the Standard Model background. Limits on new particles have been set, playing an important role the channels with tau leptons.
