| Title: | CosmiXs: cosmic messenger spectra for dark matter indirect searches |
| Date (JST): | Fri, May 23, 2025, 13:30 - 14:40 |
| Place: | Seminar Room A |
| Abstract: |
I will present CosmiXs a new tool for the calculation of the particle spectra from dark-matter annihilation/decay for dark-matter masses above 5 GeV. We have used VINCIA shower plugin that provides significant improvements with respect to the default PYTHIA dipole shower such as inclusion of full helicity/polarization information and all the Standard Model electroweak emissions. We also improved the default Monash tune for the hadronization function parameters. I will also discuss the spectra of antideuterons with improved theoretical predictions, nailing down the corresponding uncertainties to the percent level. The spectra and some python code snippets can be found on GitHub: https://github.com/ajueid/CosmiXs Talk based on: https://arxiv.org/abs/2411.04815 https://arxiv.org/abs/2312.01153 |
