Precision measurements of top-quark production with energetic photons provide a complementary probe of vector-like quarks with nonstandard radiative decays. We reinterpret the CMS differential tt̄γ measurement and the ATLAS fiducial tt̄γγ cross section to constrain the electromagnetic and chromomagnetic transition interactions of a charge-2/3 vector-like top partner, T . We consider effective...

Publicly available recasts allow LHC searches to probe signals beyond those for which they were originally designed. I will discuss their application to colour-sextet fermionic resonances predicted in composite Higgs models with partial compositeness. We use existing MadAnalysis 5 recasts of ATLAS and CMS supersymmetry searches to study simulated sextet-pair production and its decay chains....

We present a recasting study of pair production of vector-like quarks. We consider decays into a third generation quark and either a SM boson or a color singlet BSM scalar of charge 0, 1 or 2. Motivated by composite Higgs models, we assume the scalars to decay to third generation quarks. We obtain recasting bounds from MadAnalysis5 and CheckMATE on all 43 combinations of decay channels. We...

We present a method to set exclusion limits on the Minimal Supersymmetric Standard Model (MSSM) higgsino mass parameter $\mu$ using the experimental results from supersymmetric electroweak searches performed at the Large Hadron Collider (LHC).

In arXiv:2512.14502, we discussed the coverage of the electroweakino sector of the phenomenological minimal supersymmetric standard model (pMSSM) with SModelS v3.0, comparing with the ATLAS pMSSM study and investigating what can be gained by a global likelihood analysis. I will present an update of this study based on the recently released SModelS v3.2. The major novelties are the inclusion of...

Traditional SUSY searches focus on either R-parity-conserving or prompt R-parity-violating (RPV) scenarios, leaving a gap for long-lived lightest supersymmetric particles (LSPs). This study reinterprets 13 published ATLAS SUSY searches, including both prompt SUSY and long-lived particle searches, using the full Run 2 dataset of 140 fb⁻¹ at $\sqrt{s} = 13 \text{ TeV}$ to scan a wide parameter...

Beyond the Standard Model (BSM) searches show no statistically significant sign of new physics to date. However, several analyses reported small excesses, higher than 2σ SD beyond the SM expectation. In this work, clustering algorithms are used to extract more insight from existing searches and motivate a next round of BSM analyses. The flexible framework of the phenomenological Minimal...

Particle physics collider experiments provide Rivet routines as part of the analysis preservation strategy for model-independent measurements. Rivet is a C++ toolkit that allow new theoretical models to be compared to the measurements, thus aiding the development and tuning of Monte Carlo event generators as well as searches for physics beyond the Standard Model. However, analysis coverage is...

Analyses that select events with ML classifiers acting on low-level reconstructed objects are challenging to reinterpret outside of experimental collaborations, because reproducing the selection requires both the trained model and a complete detector simulation. We describe a surrogate approach in which a transformer trained only on generator-level particles predicts the decision the...

Can we map heavy-flavour decay environments directly from collision data, without specifying a particular decay hypothesis? We present a self-supervised transformer architecture that learns the structure of heavy-hadron hadronization and decays by predicting masked particle-identification information and reconstructing missing jet constituents. Using publicly available LHCb simulation and 2017...

Reinterpreting LHC results for new theories depends on access to well-documented signal simulations. Over the years, ATLAS has produced a large number of Beyond-the-Standard-Model (BSM) signal samples across many searches, but they remain scattered and hard to find, which limits their reuse. We present an effort to catalogue the publicly simulated BSM signal samples into a common, searchable...

We also introduce Bakery, a Snakemake-based rewrite of EM Creator, which runs the full efficiency-map production...

The Rivet MC-analysis toolkit is being increasingly used for BSM studies as well as measurements. This is supported by evolutions of the machinery for truth observables to also support detector emulation, lifetime-based selections of final-state particles sharing much in common with long-lived particle signatures, and driven by more complex searches relying on detailed jet structure or...

The LHC is a unique machine, it is essential that its measurements remain reusable and accessible, so that new theories and improved calculations can be confronted with data even if they were not conceived of at the time the measurements were made. This is the challenge addressed by Contur (Constraints On New Theories Using Rivet). Using a library of model-independent analyses preserved in...

Open statistical models released by the LHC experiments are transforming the reinterpretation of collider searches by providing access to the full likelihood information of experimental analyses. However, evaluating these likelihoods remains computationally expensive, particularly for analyses with many signal and control regions, limiting their use in large-scale phenomenological studies.

Reinterpreting LHC results depends on access to publishable, reusable likelihoods, yet these are distributed across a growing range of statistical frameworks, including simplified likelihoods, machine-learned statistical models, HistFactory-style JSON, RooFit workspaces, and CMS Combine datacards. Each framework has its own conventions and interfaces, making it difficult to develop...

We investigate the Higgs sector phenomenology of the minimal low scale quark-lepton unification theory. In addition to the Standard Model-like Higgs boson, the theory predicts a new CP-even neutral Higgs, a CP-odd neutral Higgs, and two charged Higgses, together with heavy right-handed neutrinos and leptoquarks. We analyze the scalar spectrum, the Yukawa structure responsible for...

Limits on spin-0 axion-like-particles (ALPs) coupling to photons are reinterpreted as constraints on massive spin-2 graviton-like-particles (GLPs) with universal coupling $\alpha_G/M_P$ (where $M_P$ is the reduced Planck mass) to the Standard Model fields. A minimally model-dependent recasting is performed, exploiting the formally analogous production and detection mechanisms for both...

Within a new physics scenario, four-fermion operators of the Nambu–Jona-Lasinio (NJL) type exhibit a strong-coupling ultraviolet (UV) fixed point at the TeV scale [[1]][1]. At this scale, two Standard Model (SM) elementary fermions, form a bound state, resulting in a composite bosons, which couples to its constituents via effective contact interactions at the compositeness scale $\Lambda...

Searches for GeV-scale feebly interacting particles commonly target simple signatures with two charged particles. Hadronic modes often dominate, but their simulation relies on fragmentation models calibrated at much higher energies, which can populate symmetry-forbidden states and misidentify the dominant allowed channels. We present exHad, a publicly available hadronization model constrained...

The preliminary analysis where the dark matter candidate comes from the approximate scale symmetry theory of a hidden sector is presented. The dynamical system of the scalar particles in the hidden sector at finite temperature and chemical potential is considered. As the cosmological application, we propose the feebly interacting dark matter with the Standard Model fields, where the preceding...
