Extended gamma-ray emission from Coy Dark Matter (2014)
Journal Article
Bœhm, C., Dolan, M. J., McCabe, C., & Spannowsky, M. (2014). Extended gamma-ray emission from Coy Dark Matter. Journal of Cosmology and Astroparticle Physics, 2014(05), Article 009. https://doi.org/10.1088/1475-7516/2014/05/009

We show that it is possible for WIMP dark matter to produce a large signal in indirect dark matter searches without producing signals elsewhere. We illustrate our point by fitting the Fermi-LAT extended galactic gamma-ray excess with a simple model o... Read More about Extended gamma-ray emission from Coy Dark Matter.

Using the CMB angular power spectrum to study Dark Matter-photon interactions (2014)
Journal Article
Wilkinson, R., Lesgourgues, J., & Boehm, C. (2014). Using the CMB angular power spectrum to study Dark Matter-photon interactions. Journal of Cosmology and Astroparticle Physics, 2014(04), https://doi.org/10.1088/1475-7516/2014/04/026

In this paper, we explore the impact of Dark Matter-photon interactions on the CMB angular power spectrum. Using the one-year data release of the Planck satellite, we derive an upper bound on the Dark Matter-photon elastic scattering cross section of...

Probing a dark matter density spike at the Galactic Center (2014)
Journal Article
Lacroix, T., Boehm, C., & Silk, J. (2014). Probing a dark matter density spike at the Galactic Center. Physical Review D, 89(6), Article 063534. https://doi.org/10.1103/physrevd.89.063534

The dark matter halo profile in the inner Galaxy is very uncertain. Yet its radial dependence toward the Galactic Center is of crucial importance for the determination of the gamma-ray and radio fluxes originating from dark matter annihilations. Here...

New method for analyzing dark matter direct detection data (2014)
Journal Article
Davis, J. H., Enßlin, T., & Boehm, C. (2014). New method for analyzing dark matter direct detection data. Physical Review D, 89(4), Article 043505. https://doi.org/10.1103/physrevd.89.043505

The experimental situation of dark matter direct detection has reached an exciting crossroads, with potential hints of a discovery of dark matter (DM) from the CDMS, CoGeNT, CRESST-II and DAMA experiments in tension with null results from xenon-based...

First Look at the Physics Case of TLEP (2014)
Journal Article
Bicer, M., DuranYildiz, H., Yildiz, I., Coignet, G., Delmastro, M., Alexopoulos, T., …Chattopadhyay, S. (2014). First Look at the Physics Case of TLEP. Journal of High Energy Physics, 2014(01), Article 164. https://doi.org/10.1007/jhep01%282014%29164

The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the absence of discoveries of phenomena beyond the Standard Model...

Affine extensions of non-crystallographic Coxeter groups induced by projection (2013)
Journal Article
Dechant, P., Boehm, C., & Twarock, R. (2013). Affine extensions of non-crystallographic Coxeter groups induced by projection. Journal of Mathematical Physics, 54(9), Article 093508. https://doi.org/10.1063/1.4820441

In this paper, we show that affine extensions of non-crystallographic Coxeter groups can be derived via Coxeter-Dynkin diagram foldings and projections of affine extended versions of the root systems E 8, D 6, and A 4. We show that the induced affine... Read More about Affine extensions of non-crystallographic Coxeter groups induced by projection.

Naturalness of Light Neutralino Dark Matter in pMSSM after LHC, XENON100 and Planck Data (2013)
Journal Article

We examine the possibility of a light (below 46 GeV) neutralino dark matter (DM) candidate within the 19-parameter phenomenological Minimal Supersymmetric Standard Model (pMSSM) in the light of various recent experimental results, especially from the...

Novel Kac-Moody-type affine extensions of non-crystallographic Coxeter groups (2012)
Journal Article

Motivated by recent results in mathematical virology, we present novel asymmetric -integer-valued affine extensions of the non-crystallographic Coxeter groups H2, H3 and H4 derived in a Kac–Moody-type formalism. In particular, we show that the affine... Read More about Novel Kac-Moody-type affine extensions of non-crystallographic Coxeter groups.

Astrophysical limits on light NMSSM neutralinos (2011)
Journal Article

It was recently shown that light LSP neutralinos could be found in the framework of the Next-to-Minimal Supersymmetric Standard Model (NMSSM). These candidates would escape known particle physics constraints even though they are relatively light. We... Read More about Astrophysical limits on light NMSSM neutralinos.

Can neutralinos in the MSSM and NMSSM scenarios still be light? (2010)
Journal Article

Since the recent results of direct detection experiments at low mass, many authors have revisited the case of light (1–10) GeV weakly interacting massive particles. In particular, there have been a few attempts to explain the results from the DAMA/LI... Read More about Can neutralinos in the MSSM and NMSSM scenarios still be light?.
