High Energy Photon Polarimetry at Lepton Colliders: Quantum Information from Converted Photons
Carlos Henrique de Lima, Navin McGinnis, David McKeen
We study high-energy photons produced at a lepton collider that convert into an pair in the detector, as a tool for measuring quantum information observables. We consider…
Low-Multiplicity Jets as Probes of GeV-Scale Light-Quark-Coupled Particles
Carlos Henrique de Lima, David McKeen, Maximilian Swiatlowski
We propose a search at the LHC for GeV-scale particles coupling predominantly to light quarks based on low-multiplicity jets. The search targets production in association with a ha…
Boosting VBF Reconstruction at Muon Colliders
Carlos Henrique de Lima
Forward muon detection at high-energy muon colliders is crucial for resolving the underlying electroweak process. Detecting these muons is challenging in current detector designs,…
Hadronic Probes of Non-Standard Neutrino Interactions
Carlos Henrique de Lima, David McKeen, John Ng +1
In this work, we study leptonic decays of hadrons as probes of light neutrinophilic scalars that mediate enhanced neutrino self-interactions. Such scalars can be emitted in process…
The Sign of Gauge-Higgs Couplings at Future Lepton Colliders
Carlos Henrique de Lima, Douglas Tuckler
This work investigates the capability of future lepton colliders to determine the sign of the gauge-Higgs coupling through the vector boson fusion (VBF) process. This channel…
