Near Threshold Kaluza-Klein Graviton Decays and the Dark Dimension
Kevin Langhoff
Near threshold, intra-tower decays of Kaluza-Klein (KK) gravitons are pure -wave, with rate in the decay products momentum , rather than the -wave $Γ\propto…
Sneaky Sneutrino Scattering at LZ
Kevin Langhoff, Huangyu Xiao
We explore a model of sneutrino dark matter in the Minimal R-Symmetric Supersymmetric Standard Model as a possible interpretation of the recent event at LZ with high reconstructed…
Heavy Higgsino Interpretation of the LZ Event
Kevin Langhoff
The LZ experiment has recently reported a keV nuclear recoil event in a region where backgrounds are expected to be low. A pure higgsino scattering inelastically through a $Z…
Baryogenesis via the CKM Matrix with Minimal Flavor Violation
Innes Bigaran, Gordan Krnjaic, Kevin Langhoff +1
It is often claimed Standard Model CP violation is insufficient for baryogenesis. We present a counterexample using minimal flavor violation (MFV) in which all CP-violating effects…
The Dark Dimension meets the Axiverse
Kevin Langhoff, Maria Ramos, Mario Reig
We explore the cosmological implications of combining dark dimension scenarios with an axiverse. If gauge sectors are realized on branes, towers of Kaluza-Klein (KK) excitations of…
Higgs Couplings at a Future Wakefield Collider
Katherine Fraser, Simon Knapen, Kevin Langhoff +1
We explore the potential of multiple possible future 10 TeV wakefield colliders to measure electroweak couplings of the Higgs boson. We find that the beam-beam interactions are not…
Vector Resonances at Muon and Wakefield Colliders
Massimo Cipressi, Kevin Langhoff, Toby Opferkuch
We explore the potential of future high-energy lepton colliders to probe heavy vector resonances. At wakefield colliders, intense beam-beam interactions produce radiation, called b…
