“…is the thermally averaged annihilation cross section w.r. Eqs. (4)(5)(6) are widely used in relic density calculations, not the least because they take the same form even when including co-annihilations [16]. These equations have been implemented to a high numerical precision since the early versions of DarkSUSY, and we refer to Refs.…”

DarkSUSY is a versatile tool for precision calculations of a large variety of dark matter-related signals, ranging from predictions for the dark matter relic density to dark matter self-interactions and rates relevant for direct and indirect detection experiments. In all of these areas significant new code additions have been made in recent years, since the release of DarkSUSY 6 in 2018, which we summarize in this overview. In particular, DarkSUSY now allows users to compute the relic density for feebly interacting massive particles via the freeze-in mechanism, but also offers new routines for freeze-out calculations in the presence of secluded dark sectors as well as for models where kinetic equilibrium is not fully established during the freeze-out process. On the direct detection side, the effect of cosmic-ray upscattering of dark matter has been fully implemented, leading to a subdominant relativistic component in the expected dark matter flux at Earth. Finally, updated yields relevant for indirect searches with gamma rays, neutrinos or charged cosmic rays have been added; the new default spectra are based on a large number of Pythia 8 runs, but users can also easily switch between various alternative spectra. Further code details, including a manual and various concrete example applications, are provided at www.darksusy.org.

“…Consequently, there is a huge demand on precision calculations both for the relic density and rates associated to other potentially observable DM signals. DarkSUSY [2,3] is one of the major public and generic codes to perform such calculations (complemented by MicrOMEGAs [4] and MadDM [5], which each have a somewhat different focus [6]).…”

“…The possible models that could lead to a stable particle are quite obvious in this parametrization and can be classified in two groups depending on whether the complex field S acquires a vacuum expectation value JHEP11(2021)202 (VEV) or not. In this work, we focus on the former case because it helps to avoid DD constraints [37][38][39][40][41]. Moreover it can also help to alleviate the instability problems of the scalar potential of the SM (see for instance ref.…”

We study the case of a pseudo-scalar dark matter candidate which emerges from a complex scalar singlet, charged under a global U(1) symmetry, which is broken both explicitly and spontaneously. The pseudo-scalar is naturally stabilized by the presence of a remnant discrete symmetry: dark CP. We study and compare the phenomenology of several simplified models with only one explicit symmetry breaking term. We find that several regions of the parameter space are able to reproduce the observed dark matter abundance while respecting direct detection and invisible Higgs decay limits: in the resonances of the two scalars, featuring the known as forbidden or secluded dark matter, and through non-resonant Higgs-mediated annihilations. In some cases, combining different measurements would allow one to distinguish the breaking pattern of the symmetry. Moreover, this setup admits a light DM candidate at the sub-GeV scale. We also discuss the situation where more than one symmetry breaking term is present. In that case, the dark CP symmetry may be spontaneously broken, thus spoiling the stability of the dark matter candidate. Requiring that this does not happen imposes a constraint on the allowed parameter space. Finally, we consider an effective field theory approach valid in the pseudo-Nambu-Goldstone boson limit and when the U(1) breaking scale is much larger than the electroweak scale.

“…A thorough review of many DM tools can be found in [26] The revolution in the field of BSM inference came with the advent of model-independent tools. The front-runner for SM fits is HEPFit [57], built upon a Bayesian Markov chain Monte Carlo, which includes a vast library of electroweak precision, Higgs and flavour observables, and can also work with BSM models [58,59].…”
