abstract="We introduce version 2.0 of Z{\textquoteright}-explorer, a software tool that provides a simple, fast, and user-friendly test of models with an extra U (1) gauge boson (Z{\textquoteright}) against experimental LHC results. The main novelty of the second version is the inclusion of missing energy searches, as the first version only included final states into SM particles. Hence Z{\textquoteright}-explorer 2.0 is able to test dark matter models where the Z{\textquoteright} acts as an s-channel mediator between the Standard Model and the dark sector, a widespread benchmark employed by the ATLAS and CMS experimental collaborations. To this end, we perform here the first public reinterpretation of the most recent ATLAS mono-jet search with 139 fb-1. In addition, the corresponding searches in the visible final states have also been updated. We illustrate the power of our code by re -obtaining public plots and also showing novel results. In particular, we study the cases where the Z{\textquoteright} couples strongly to top quarks (top-philic), where dark matter couples with a mixture of vector and axial-vector couplings, and also perform a scan in the parameter space of a string inspired Stuckelberg model. Z{\textquoteright}-explorer 2.0 is publicly available on GitHub. Program summary Program Title: Z{\textquoteright}-explorer 2.0 CPC Library link to program files: https://doi .org /10 .17632 /k7tdp8kwgf .2 Developer{\textquoteright}s repository link: https://github .com /ro -sanda /Z--explorer-2 .0 Licensing provisions: GPLv3 Programming language: C++ and bash Nature of problem: New SM neutral gauge bosons, Z{\textquoteright}, are ubiquitously present in models of New Physics. In order to confront these models versus a large and ever-growing library of LHC searches, Z{\textquoteright}-explorer 1.0 had already included all final states including Standard Model particles. Notably, the previous version of this tool lacked the so-called invisible final states manifested as a momentum imbalance in the transverse plane ({\textquoteleft}{\textquoteleft}missing energy{\textquoteright}{\textquoteright}). These searches help to probe mediators into a dark sector, where a dark matter candidate resides. Solution method: Z{\textquoteright}-explorer encodes the production cross sections for Z{\textquoteright} bosons at the LHC as a function of their mass, allowing for a fast evaluation of the exclusion limits. This version of Z{\textquoteright}-explorer includes a careful validation of the latest search with one energetic jet (mono-jet) performed by the ATLAS collaboration. Hence one can now test if a given point in parameter space is excluded by both visible and invisible searches. The modular structure of the code has been kept, which allows for potential additions (low-energy constraints, flavor, extrapolation to future colliders).",
