Invisible decays of axion-like particles: constraints and prospects
Luc Darmé, Federica Giacchino, Enrico Nardi +1
Axion-like particles (ALPs) can provide a portal to new states of a dark sector. We study the phenomenology of this portal when the ALP mainly decays invisibly, while its interacti…
Selective enhancement of the QCD axion couplings
Luc Darmé, Luca Di Luzio, Maurizio Giannotti +1
We present a mechanism wherein the QCD axion coupling to nucleons, photons, or electrons, can be enhanced selectively without increasing the axion mass. We focus in particular on t…
Solar axions cannot explain the XENON1T excess
Luca Di Luzio, Marco Fedele, Maurizio Giannotti +2
We argue that the interpretation in terms of solar axions of the recent XENON1T excess is not tenable when confronted with astrophysical observations of stellar evolution. We discu…
New production channels for light dark matter in hadronic showers
Andrea Celentano, Luc Darmé, Luca Marsicano +1
Hadronic showers transfer a relevant amount of their energy to electromagnetic subshowers. We show that the generation of "secondary" dark photons in these sub-showers is significa…
