The paper says
“We do not observe a significant signal and we set 90% upper limits of σ(e+e− → W′W′ → (e+e−)(e+e−)) < (15−70)ab, σ(e+e− → W′W′ → (e+e−)(μ+μ−)) < (15−40)ab, and σ(e+e− → W′W′ → (μ+μ−)(μ+μ−)) < (11−17)ab in the W′ mass range between 0.24 and 5.3GeV.”

Abstract
Motivated by recent models proposing a hidden sector with ∼GeV scale force carriers, we present a search for a narrow dilepton resonance in 4 lepton final states using 536fb−1 collected by the BaBar detector. We search for the reaction, e+e− → W′W′ → (l+l−)(l′ +l′−), where the leptons carry the full 4-momentum and the two dilepton pair invariant masses are equal. We do not observe a significant signal and we set 90% upper limits of σ(e+e− → W′W′ → (e+e−)(e+e−)) < (15−70)ab, σ(e+e− → W′W′ → (e+e−)(μ+μ−)) < (15−40)ab, and σ(e+e− → W′W′ → (μ+μ−)(μ+μ−)) < (11−17)ab in the W′ mass range between 0.24 and 5.3GeV. Under the assumption that the W′ coupling to electrons and muons is the same, we obtain a combined upper limit of σ(e+e− → W′W′ → (l+l−)(l′ +l′−)) < (25−60)ab. Using these limits, we constrain the product of the SM-dark sector mixing and the dark coupling constant in the case of a non-Abelian Higgsed dark sector.

While a great deal of the parameter space for neutral LOLIPs is unexplored, some constraints already exists. �Collider constraints from low energy experiments have been covered in many different ways in [ref] . �However, if DM particles can annihilate into LOLIPs there are additional indirect constraints on some part of the parameter space. �These constraints roughly fall into three categories: existing neutrino telescope bounds, photon and electron fluxes from the Sun, and DM direct detection experiments. � If the LOLIPs subsequently decay into muons, then SuperK bounds from up-going muon searches from both the Sun and the Earth are relevant [ref] . �As explained in Section [ref], these searches are just a rough bound on the LOLIP scenario because utilize on neutrino induced muon events in SuperK. �

Most searches for the dark photon rely on the observation of the products of its decay after it has been produced in low-energy terrestrial experiments [ref] , although some search strategies are sensitive even to invisibly decaying or effectively stable dark photons [ref] .
