Using INTEGRAL x-ray and AMS-02 positron data, the authors set lower limits on dark photon and scalar dark matter decay lifetimes from 10^25 to 10^29 seconds across 1 MeV to 2 TeV masses.

abstract
A sector with QCD-like strong dynamics is common in models of non-standard physics. Such a model could be accessible in LHC searches if both confinement and big-quarks charged under the confining group are at the TeV scale. Big-quark masses at this scale can be explained if the new fermions are chiral under a new $U(1)^\prime$ gauge symmetry such that their bare masses are related to the $U(1)^\prime$-breaking and new confinement scales. Here we present a study of a minimal GUT-motivated and gauge anomaly-free model with implications for the LHC Run 2 searches. We find that the first signatures of such models could appear as two gauge boson resonances. The chiral nature of the model could be confirmed by observation of a $Z^\prime \gamma$ resonance, where the $Z^\prime$ naturally has a large leptonic branching ratio because of its kinetic mixing with the hypercharge gauge boson.
