Branching ratios for Higgs-mixed scalars at the GeV scale from hadronisation models with conservation laws
Stefan Gieseke, Felix Kahlhoefer, Henry Seebach
We investigate the decay modes of a CP-even scalar boson that mixes with the Standard Model Higgs boson, focusing on the mass range between 2 GeV and . Starting from a h…
Riding the dark matter wave: Novel limits on general dark photons from LISA Pathfinder
Jonas Frerick, Joerg Jaeckel, Felix Kahlhoefer +1
We note the possibility to perform a parametrically improved search for gauged baryon () and baryon minus lepton () Dark Photon Dark Matter (DPDM) using auxiliary channel d…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Leading Logs in QCD Axion Effective Field Theory
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The axion is much lighter than all other degrees of freedom introduced by the Peccei-Quinn mechanism to solve the strong CP problem. It is therefore natural to use an effective fie…
On the challenges of searching for GeV-scale long-lived particles at the LHC
Elias Bernreuther, Juliana Carrasco Mejia, Felix Kahlhoefer +2
Many models of dark matter predict long-lived particles (LLPs) that can give rise to striking signatures at the LHC. Existing searches for displaced vertices are however tailored t…
The Semi-Classical Regime for Dark Matter Self-Interactions
Brian Colquhoun, Saniya Heeba, Felix Kahlhoefer +2
Many particle physics models for dark matter self-interactions - motivated to address long-standing challenges to the collisionless cold dark matter paradigm - fall within the semi…
