Tackling ALP searches in meson decays with ALPaca: a phenomenological approach

Part of the community has intensively searched for ALP signals, as well as conducted dedicated data analyses to identify potential evidence of New Physics compatible with an ALP, resulting in constraints on the ALP parameter space. Considering the advancements both in theoretical studies as well as experimental measurements, it is now the time to present a tool, \alpaca, that facilitates the combination among the different information on ALP physics. We showcase a phenomenological analysis of the ALP theory using the most up-to-date data from flavour facilities, to show both the latest constraints and the potential of \alpaca. The program is publicly available at https://github.com/alp-aca/alp-aca.
