Characterizing Heavy Neutral Leptons: Measuring Parameters, Discriminating Majorana versus Dirac, and Using FASER2 as a Trigger for ATLAS
Jonathan L. Feng, Alec Hewitt, Daniel La Rocco +1
This work explores the potential of the proposed FASER2 experiment at the LHC to determine the properties of a discovered heavy neutral lepton (HNL), including its mass, couplings,…
Spin Correlations in Dark Photon Searches
Jonathan L. Feng, Miša Toman, Eli Welch
We investigate the spin correlations between production and decay in the process where dark photons are produced in pseudoscalar meson decays, for example, , an…
Flavor at FASER: Discovering Light Scalars Beyond Minimal Flavor Violation
Reuven Balkin, Noam Burger, Jonathan L. Feng +1
We study a simple class of flavored scalar models, in which the couplings of a new light scalar to standard-model fermions are controlled by the flavor symmetry responsible for fer…
FPF@FCC: Neutrino, QCD, and BSM Physics Opportunities with Far-Forward Experiments at a 100 TeV Proton Collider
Roshan Mammen Abraham, Jyotismita Adhikary, Jonathan L. Feng +7
Proton-proton collisions at energy-frontier facilities produce an intense flux of high-energy light particles, including neutrinos, in the forward direction. At the LHC, these part…
Simulating Heavy Neutral Leptons with General Couplings at Collider and Fixed Target Experiments
Jonathan L. Feng, Alec Hewitt, Felix Kling +1
Heavy neutral leptons (HNLs) are motivated by attempts to explain neutrino masses and dark matter. If their masses are in the MeV to several GeV range, HNLs are light enough to be…
Discovering Quirks through Timing at FASER and Future Forward Experiments at the LHC
Jonathan L. Feng, Jinmian Li, Xufei Liao +2
Quirks are generic predictions of strongly-coupled dark sectors. For weak-scale masses and a broad range of confining scales in the dark sector, quirks can be discovered only at th…
