Test of lepton universality and search for lepton flavor violation in Upsilon(1S,2S,3S) decays at CLEO

TL;DR

This paper reports on analyses testing lepton universality and lepton flavor conservation in Upsilon decays at CLEO, aiming to identify potential deviations from the Standard Model predictions.

Contribution

It introduces new analysis techniques and preliminary results for lepton universality and flavor violation in Upsilon decays at CLEO.

Findings

Initial results support lepton universality in Upsilon decays.

No evidence of lepton flavor violation observed so far.

Analysis methods set the stage for more precise future tests.

Abstract

We present the analysis technique and preliminary results of two ongoing analyses at CLEO which put lepton universality and lepton flavor conservation to the test in Upsilon decays.
