摘要

Lepton Flavour Violation (LFV) is one of the paramount topics of High Energy Physics in recent days and \(\Upsilon\) Υ is one such suited particle for such explorations. Here, we have studied various LFV decays of \(\Upsilon\) Υ incorporating the contribution of \(Z'\) Z ′ boson. The New Physics (NP) couplings are constrained with the available experimental data using \(\chi ^2\) χ 2 fitting technique.
