Discovering neutrino tridents at the Large Hadron Collider
arxiv(2024)
摘要
Neutrino trident production of di-lepton pairs is well recognized as a
sensitive probe of both electroweak physics and physics beyond the Standard
Model. Although a rare process, it could be significantly boosted by such new
physics, and it also allows the electroweak theory to be tested in a new
regime. We demonstrate that the forward neutrino physics program at the Large
Hadron Collider offers a promising opportunity to measure for the first time,
dimuon neutrino tridents with a statistical significance exceeding 5σ.
We present predictions for various proposed experiments and outline a specific
experimental strategy to identify the signal and mitigate backgrounds, based on
"reverse tracking" dimuon pairs in the FASERν2 detector. We also discuss
prospects for constraining beyond Standard Model contributions to neutrino
trident rates at high energies.
