Contrastive Pretraining on Real LHC Jets: Transfer, Scorer Dependence and Mass Distortion

We compare contrastive pretraining on real AspenOpenJets and simulated LHC Olympics jets for background-based anomaly ranking, using matched random backbones and jet observables as controls. Equal training budgets comprise 100,000 jets per domain, one real-data shard and three se...
