When a dark matter halo moves through a background of dark matter particles, self-interactions can lead to both deceleration and evaporation of the halo and thus shift its centroid relative to the…
Resolving astrophysical uncertainties in dark matter direct detection

We study the impact of the assumed velocity distribution of galactic dark matter particles on the interpretation of results from nuclear recoil detectors. By converting experimental data to variables…
Boosted objects: a probe of beyond the standard model physics

We present the report of the hadronic working group of the BOOST2010 workshop held at the University of Oxford in June 2010. The first part contains a review of the potential of hadronic decays of…
Technicolor walks at the LHC

- 4 September 2008
We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable walking technicolor models. We study and compare the Drell-Yan and vector boson fusion…
Minimal walking technicolor: Setup for collider physics
- R. Foadi, M. Frandsen, T. Ryttov, Francesco Sannino

- 12 June 2007
Different theoretical and phenomenological aspects of the minimal and nonminimal walking technicolor theories have recently been studied. The goal here is to make the models ready for collider…
Loop-induced dark matter direct detection signals from gamma-ray lines

Improved limits as well as tentative claims for dark matter annihilation into γ-ray lines have been presented recently. We study the direct detection cross section induced from dark matter…
The Unbearable Lightness of Being: CDMS versus XENON
- M. Frandsen, F. Kahlhoefer, C. McCabe, S. Sarkar, K. Schmidt-Hoberg

- 22 April 2013
Abstract The CDMS-II collaboration has reported 3 events in a Si detector, which are consistent with being nuclear recoils due to scattering of light dark matter particles. We discuss the tension…
Asymmetric dark matter and the sun.

It is shown that cold dark matter particles with an intrinsic matter-antimatter asymmetry can solve the "solar composition problem" and the predicted small decrease in the low energy neutrino fluxes may be measurable by the Borexino and SNO+ experiments.
LHC and Tevatron bounds on the dark matter direct detection cross-section for vector mediators
- M. Frandsen, F. Kahlhoefer, A. Preston, S. Sarkar, K. Schmidt-Hoberg
- Physics
- 17 April 2012
A bstractWe study the interactions of a new spin-1 mediator that connects the Standard Model to dark matter. We constrain its decay channels using monojet and monophoton searches, as well as searches…
Technicolor Higgs boson in the light of LHC data
- A. Belyaev, Matthew S. Brown, R. Foadi, M. Frandsen
- Physics
- 9 September 2013
We consider scenarios in which the 125 GeV resonance observed at the Large Hadron Collider is a Technicolor (TC) isosinglet scalar, the TC Higgs. By comparison with quantum chromodynamics, we argue…
