“…Furthermore, even if the particles decay too rapidly to be dark matter, they can have observable consequences as long as they are sufficiently long lived, as discussed for example in refs. [2,5,[51][52][53][54][55][56][57][58][59][60]. 4 The order of presentation will be as follows.…”

Analytic and numerical techniques are presented for computing gravitational production of scalar particles in the limit that the inflaton mass is much larger than the Hubble expansion rate at the end of inflation. These techniques rely upon adiabatic invariants and time modeling of a typical inflaton field which has slow and fast time variation components. A faster computation time for numerical integration is achieved via subtraction of slowly varying components that are ultimately exponentially suppressed. The fast oscillatory remnant results in production of scalar particles with a mass larger than the inflationary Hubble expansion rate through a mechanism analogous to perturbative particle scattering. An improved effective Boltzmann collision equation description of this particle production mechanism is developed. This model allows computation of the spectrum using only adiabatic invariants, avoiding the need to explicitly solve the inflaton equations of motion.

“…For DM masses above the electroweak (EW) scale, the neutrino flux generation in aro is coupled to a new computation of the EW correction which also accounts for polarization of annihilation and decay states and the evolution of the polarized particles to the EW scale [11]. As EW interactions are only partially implemented in PYTHIA, this calculation incorporates a more complete consideration such as the missing triple gauge couplings in the EW sector.…”

“…In this work, we introduce a new tool, aro , to compute the neutrino fluxes from WIMP annihilations and decays in the Sun, the Earth, and the Galactic Halo. For DM masses below the electroweak (EW) scale, the neutrino flux produced from DM annihilation or decay is computed using PYTHIA-8.2, while for masses above this scale a recent calculation by Bauer, Rodd, and Webber (BRW) [11] is used. The propagation of neutrinos from their production region to the detector is computed with the help of the neutrino propagation software SQuIDS (developed from SQuIDS [12]).…”

Indirect searches for signatures of corpuscular dark matter have been performed using all cosmic messengers: gamma rays, cosmic rays, and neutrinos. The search for dark matter with neutrinos is important since they are the only courier that can reach detectors from dark matter processes in dense environments, such as the core of the Sun or Earth, or the edge of the observable Universe. One thing essential to experiments is the prediction of the neutrino signature in the detector. I will introduce aro , a software that bridges the dark sector and Standard Model by predicting neutrino fluxes from different celestial dark matter agglomerations in diverse scenarios. This package includes an updated computation of neutrino production and propagation to the detector.

Astrophysical neutrinos with energies higher than > 10 PeV have not been measured yet, therefore, we do not know what kind of sources are contributing to this high energy neutrino flux. Concretely, we are interested in testing the hypothesis in which we have a hidden contribution coming from the decay of heavy dark matter particles. The first neutrino radio telescopes will be constructed during the following decade, having as a principal goal the detection of the cosmogenic neutrinos, and being able to disentangle the principal source contributing at these high energies for the astrophysical neutrino flux. In this work we study the projected sensitivity of up-coming neutrino radio telescopes, such as RNO-G, GRAND and IceCube-Gen2 radio array, to decaying dark matter scenarios. We perform a forecast analysis in order to place conservative constraints on the lifetime of dark matter within the range DM = [10 7 − 10 15 ] GeV after assuming the dominant astrophysical neutrino source, the one that will act as our background for the hidden dark matter signal. These forecasted limits open a new parameter space for some decaying channels, and complement the limits obtained for the channel due to its multi-messenger agreement.
