Is supersymmetry loosing ground as a compelling explanation for dark matter? Or is there still enough experimental evidence to support our faith in supersymmetric dark matter? In search of quantitative answers, focusing on dark matter properties, I review the latest GAMBIT results for various supersymmetric models covering the CMSSM, NUHM1 and 2, MSSM7 and MSSM9.
The current experimental precision from PLANCK on the extraction of the relic abundance of Dark Matter calls for very precise prediction from the theory side to be able to extract meaningful information. In this study we compute the full set of radiative corrections entering the calculation of the relic density of Dark Matter in the Inert Doublet Model and weigh their impact on its prediction...
Supergravity and string theories usually have particles, such as a modulus, with only gravitational interactions. These moduli fields arise due to the flat directions in the above theories. We inspect the possibility that these moduli fields acting as a mediator between the dark sector and the Standard Model, from an effective field theory perspective. We show that in this scenario, dark...
SuperIso Relic is a public computing program for the calculation of flavour observables and relic density in supersymmetry (MSSM and NMSSM). We present new extensions of the code dedicated to the calculation of dark matter direct and indirect detection constraints from the latest experiment results. After presenting the new features of the program in particular the treatment of the relevant...
The investigation of the composition of the extra-galactic gamma-ray background (EGB) is a powerful tool to search for dark matter signals in the gamma-ray sky. In the last few years, statistical analysis methods have been demonstrated to outperfom classic detection methods in decomposing the EGB. In particular, the 1-point photon counts statistics (1pPDF) permits to resolve the population of...
Revealing the nature of dark matter is one of the most riveting open tasks of modern astronomy and cosmology. To this end, observing and analyzing high-energy gamma-rays provides a promising and highly-effective tool which is, in particular, well-suited to constrain Weakly Interacting Massive Particle (WIMP) models.
Being currently in its pre-construction phase, the Cherenkov Telescope Array...
osmic-ray observations provide a powerful probe of dark matter annihilation in the Galaxy. In this paper we derive constraints on heavy dark matter from the recent precise AMS-02 antiproton data. We consider all possible annihilation channels into pairs of standard model particles. Furthermore, we interpret our results in the context of minimal dark matter, including higgsino, wino and...
The cosmic ray(CR) positrons and antiprotons are often regarded as the products of collisions of CR nucleons with the interstellar medium. However this conclusion is challenged by recent experimental data. In this work, we choose the latest AMS-02 data to analyze the astrophysical background of CR positrons and antiprotons based on the GALPROP code for CR propagation and QGSJET-II-04 for ...
In this talk, we study the possible models trying to reconcile the tension between the CDMS-Si signals and null experiments. In particular, we focus on the models with the following properties: isospin-violating couplings, exothermic scatterings, and/or a light mediator. In the light of the latest constraints from LUX, PandaX-II, XENON1T, CDMSlite and PICO-60, we find that, for almost all the...
This talk will introduce the use of surrogate model techniques for direct detection of dark matter. We have developed a tool, RAPIDD, that replaces the exact calculation of the dark matter differential rate (which in general involves up to three nested integrals) with a much faster parametrization in terms of ordinary polynomials of the dark matter mass and couplings, obtained in an initial...
