Cosmic ray boosted dark matter with momentum dependent interactions can explain the LZ 248 keV event
Matti Heikinheimo, Niklas Zimmermann
The LZ experiment has recently reported an observation of a single event with characteristics of a nuclear recoil at a high recoil energy of 248 keV, where no background events are…
Anatomy of real intermediate state-subtraction scheme
Kalle Ala-Mattinen, Matti Heikinheimo, Kimmo Kainulainen +1
We study the origin of the real intermediate state subtraction problem and compare its different solutions. We show that the ambiguity in subtraction schemes arises from the on-she…
Daily and annual modulation rate of low mass dark matter in silicon detectors
Abolfazl Dinmohammadi, Matti Heikinheimo, Nader Mirabolfathi +4
Low threshold detectors with single-electron excitation sensitivity to nuclear recoil events in solid-state detectors are also sensitive to the crystalline structure of the target…
Observational Properties of Feebly Coupled Dark Matter
Matti Heikinheimo, Tommi Tenkanen, Kimmo Tuominen +1
We show that decoupled hidden sectors can have observational consequences. As a representative model example, we study dark matter production in the Higgs portal model with one rea…
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…
