Flavor-to-Top Transfer: A Unified EFT-Constrained Embedding for Correlated Anomalies

Atkinson et al. (2024) show how top measurements can competitively constrain interactions tied to flavor anomalies, while Atkinson et al. (2022) map collider–flavor complementarity in 2HDMs. Meanwhile, Cabarcas et al. (2022) highlight tensions when fitting B anomalies (TVB model) against LHC constraints. We propose a multi-domain embedding that ingests low-energy flavor observables (R(D()), R(K()), differential distributions) and high-energy collider data (tt̄, single top, dileptons, jets+MET), trained with a contrastive objective where “positive pairs” are data or simulations connected by the same EFT Wilson coefficient vector under RGE evolution from μb to μTeV. “Negative pairs” are orthogonal operator directions or SM-only controls. This integrates the anomaly-preserving representation idea (Metzger et al., 2025) with operator-aware supervision, yielding a latent space in which clusters correspond to EFT fingerprints rather than processes or experiments. We then perform model-independent anomaly scans in that space and ask: which operator directions best explain any joint deviation? We can stress-test concrete models (TVB, 2HDM types I/II) against the learned EFT manifold to see if they map to the same latent direction as the data. Novelty: instead of fitting post-hoc across disparate datasets, we co-learn a representation that encodes EFT structure and RGE correlations a priori. Impact: a more cohesive way to diagnose whether flavor hints and collider wrinkles are two faces of the same new physics, or incompatible—accelerating theory–experiment iteration.
