Signal of four muons or more from a vector-like lepton decaying to a muon-philic boson at the LHC
Abstract
We propose a novel possibility to detect a very distinctive signal with more than four muons originating from pair-produced vector-like leptons decaying to a muon-philic Z' boson. These new particles are good candidates to explain the anomalies in the muon anomalous magnetic moment and the b → sℓℓ processes. The doublet (singlet) vector-like leptons lighter than 1.3 (1.0) TeV are excluded by the latest data at the LHC if BR(E → Z'μ) = 1. We also show that the excess in the signal region with more than five leptons can be explained by this scenario if the vector-like lepton is a weak singlet, with mass about 400 GeV and BR(E → Z'μ) = 0.25. The future prospects at the HL-LHC are discussed.
