ELMAG is a Monte Carlo program made to simulate electromagnetic cascades initiated by high-energy photons interacting with the extragalactic background light. Photons propagating in an external magnetic field may further oscillate into axions or axion-like particles (ALPs). We have implemented axions into ELMAG, complementing thereby the usual description of photon-axion oscillations with a...
Automated tools for the computation of amplitudes and cross sections have become the backbone of phenomenological studies beyond the standard model. We present the latest developments in MadDM, a calculator of dark-matter observables based on MadGraph5_aMC@NLO. The new version enables the fully automated computation of loop-induced annihilation processes, relevant for indirect detection of...
In this talk, I discuss the progress on the particle physics modeling of anti-proton spectra from dark matter indirect detection searches and the QCD uncertainties on these predictions. First, I discuss the challenges in the measurements of baryon differential yields at LEP and the way we used to deal with these. Then, we discuss the up-to date fits of the fragmentation function including...
