abstract="This paper presents a search for a new Z{\textquoteright} vector gauge boson with the ATLAS experiment at the Large Hadron Collider using pp collision data collected at root s = 13TeV, corresponding to an integrated luminosity of 139 fb(-1). The new gauge boson Z{\textquoteright} is predicted by L-mu -- L-tau models to address observed phenomena that can not be explained by the Standard Model. The search examines the four-muon (4 mu) final state, using a deep learning neural network classifier to separate the Z{\textquoteright} signal from the Standard Model background events. The di-muon invariant masses in the 4 $\mu$events are used to extract the Z{\textquoteright} resonance signature. No significant excess of events is observed over the predicted background. Upper limits at a 95{\%} confidence level on the Z{\textquoteright} production cross-section times the decay branching fraction of pp -> Z{\textquoteright} $\mu$$\mu$-> 4 $\mu$are set from 0.31 to 4.3 fb for the Z{\textquoteright} mass ranging from 5 to 81 GeV. The corresponding common coupling strengths, g(Z{\textquoteright}), of the Z{\textquoteright} boson to the second and third generation leptons above 0.003 -- 0.2 have been excluded.",
