Galactic Centre GeV Photons from Dark Technicolor
Matti Heikinheimo, Christian Spethmann
We present a classically scale-invariant model with a confining dark sector, which is coupled to the Standard Model through the Higgs portal. The galactic centre gamma ray excess c…
Testing Right-Handed Currents at the LHC
Matti Heikinheimo, Martti Raidal, Christian Spethmann
The CMS Collaboration has published two different searches for new physics that contain possible hints for excesses in and final states. Interpreting those hints as a…
Dark photons and resonant monophoton signatures in Higgs boson decays at the LHC
Emidio Gabrielli, Matti Heikinheimo, Barbara Mele +1
Motivated by dark-photon scenarios extensively considered in the literature, we explore experimentally allowed models where the Higgs boson coupling to photon and dark phot…
