Indirect searches for realistic sub-GeV Dark Matter models
Marco Cirelli, Arpan Kar, Halim Shaikh
Indirect searches for Dark Matter (DM) particles with mass in the MeV -- GeV scale have received significant attention lately. Pair-annihilations of such DM particles in the Galaxy…
Prospects of future MeV telescopes in probing weak-scale Dark Matter
Marco Cirelli, Arpan Kar
Galactic weak-scale Dark Matter (DM) particles annihilating into lepton-rich channels not only produce gamma-rays via prompt radiation but also generate abundant energetic electron…
Putting all the X in one basket: Updated X-ray constraints on sub-GeV Dark Matter
Marco Cirelli, Nicolao Fornengo, Jordan Koechler +2
Sub-GeV dark matter particles can annihilate or decay producing e^\pm pairs which upscatter the low-energy photon fields in the Galaxy and generate an X-ray emission (via the Inver…
AMS-02 antiprotons and dark matter: Trimmed hints and robust bounds
Francesca Calore, Marco Cirelli, Laurent Derome +4
Based on 4 yr AMS-02 antiproton data, we present bounds on the dark matter (DM) annihilation cross section vs. mass for some representative final state channels. We use recent cosm…
Integral X-ray constraints on sub-GeV Dark Matter
Marco Cirelli, Nicolao Fornengo, Bradley J. Kavanagh +1
Light Dark Matter (DM), defined here as having a mass between 1 MeV and about 1 GeV, is an interesting possibility both theoretically and phenomenologically, at one of the frontier…
Homeopathic Dark Matter, or how diluted heavy substances produce high energy cosmic rays
Marco Cirelli, Yann Gouttenoire, Kalliopi Petraki +1
We point out that current and planned telescopes have the potential of probing annihilating Dark Matter (DM) with a mass of O(100) TeV and beyond. As a target for such searches, we…
Asymmetric dark matter: residual annihilations and self-interactions
Iason Baldes, Marco Cirelli, Paolo Panci +3
Dark matter (DM) coupled to light mediators has been invoked to resolve the putative discrepancies between collisionless cold DM and galactic structure observations. However, -r…
Dark Matter's secret liaisons: phenomenology of a dark U(1) sector with bound states
Marco Cirelli, Paolo Panci, Kalliopi Petraki +2
Dark matter (DM) charged under a dark U(1) force appears in many extensions of the Standard Model, and has been invoked to explain anomalies in cosmic-ray data, as well as a self-i…
Physics at a 100 TeV pp collider: beyond the Standard Model phenomena
T. Golling, M. Hance, P. Harris +111
This report summarises the physics opportunities in the search and study of physics beyond the Standard Model at a 100 TeV pp collider.
Updated galactic radio constraints on Dark Matter
Marco Cirelli, Marco Taoso
We perform a detailed analysis of the synchrotron signals produced by Dark Matter annihilations and decays. We consider different set-ups for the propagation of electrons and posit…
Gamma ray tests of Minimal Dark Matter
Marco Cirelli, Thomas Hambye, Paolo Panci +2
We reconsider the model of Minimal Dark Matter (a fermionic, hypercharge-less quintuplet of the EW interactions) and compute its gamma ray signatures. We compare them with a number…

We enlarge the set of recipes and ingredients at disposal of any poor particle physicist eager to cook up signatures from weak-scale Dark Matter models by computing two secondary e…
Wino-like Minimal Dark Matter and future colliders
Marco Cirelli, Filippo Sala, Marco Taoso
We extend the Standard Model with an EW fermion triplet, stable thanks to one of the accidental symmetries already present in the theory. On top of being a potential Dark Matter ca…
