Analysis
This paper investigates the potential for discovering heavy, photophobic axion-like particles (ALPs) at a future 100 TeV proton-proton collider. It focuses on scenarios where the diphoton coupling is suppressed, and electroweak interactions dominate the ALP's production and decay. The study uses detector-level simulations and advanced analysis techniques to assess the discovery reach for various decay channels and production mechanisms, providing valuable insights into the potential of future high-energy colliders to probe beyond the Standard Model physics.
Key Takeaways
- •The study focuses on photophobic ALPs, where diphoton decay is suppressed.
- •It analyzes three final states: Zγjj, tri-W, and W+W-jj.
- •A boosted-decision-tree (BDT) classifier is used for signal-background separation.
- •The paper presents discovery sensitivities for the ALP--W coupling at a 100 TeV collider.
- •The research extends the discovery reach beyond 14 TeV projections.
