Search for Lepton-Flavor-Violating Tau Decays at the B-factories
Alberto Lusiani
TL;DR
This paper reviews the efforts and results from BaBar and Belle B-factories in searching for lepton-flavor-violating tau decays, highlighting the current upper limits and lack of evidence.
Contribution
It provides a comprehensive review of experimental upper limits on LFV tau decays from the B-factories BaBar and Belle.
Findings
No evidence of LFV tau decays found
Set new upper limits on LFV decay branching fractions
Summarizes the status of LFV searches at B-factories
Abstract
Both the B-factories BaBar and Belle have ended data-taking and have mostly completed the data analysis aimed at searching Lepton Flavor Violation in Tau decays. No evidence of LFV in tau decays has been found yet. We review in the following the experimental upper limits that have been set.
