  "abstract": "We discuss exclusive production of $π^+ π^-$ pairs in diffractive $γp$ and in $pp$ collisions at high energies, considering resonant ($ρ(770)$, $ω$, $f_2(1270)$) and non-resonant (Drell-Söding) contributions within the tensor-pomeron approach. For the $γp \\to π^+ π^- p$ reaction, the model describes well the H1 data in the region $M_{ππ} \\lesssim 1.2$ GeV. We discuss the important role of the Drell-Söding mechanism in shaping the resonance line. We also predict differential cross sections for the $pp \\to pp π^+ π^-$ reaction at $\\sqrt{s} = 13$ TeV where at least one proton emits a virtual photon. These findings are relevant for the central exclusive production of $π^+ π^-$ pairs in the context of ALICE, ATLAS, CMS, and LHCb measurements in hadron-hadron collisions at the LHC, especially under experimental selections using only rapidity-gap conditions. Additionally, our results are also applicable to $π^+ π^-$ production in ultraperipheral $p$A/AA collisions at the LHC and to photo- and electroproduction of $π^+ π^-$ at future electron-proton/ion colliders (EIC, LHeC).",
