Dark sector searches with high-intensity positron beams in the CERN North Area
F. Arias-Aragón, L. Darmé, R. Gargiulo +6
Dark sector models present a rich phenomenology that requires high-intensity beams and precision detectors for thorough exploration. The NA62 experiment has already published sever…
Atoms as electron accelerators for measuring the hadrons cross section
Fernando Arias-Aragón, Luc Darmé, Giovanni Grilli di Cortona +1
The hadronic vacuum polarization contribution to can be determined via dispersive methods from hadrons data. We propose a novel approach to measure the hadro…
Indirect new physics effects on confront the window discrepancies and the CMD-3 result
Luc Darmé, Giovanni Grilli di Cortona, Enrico Nardi
Recent lattice determinations of the hadronic vacuum polarization contribution to the muon anomalous magnetic moment have confirmed the discrepancy with the data-dr…
Resonant search for the X17 boson at PADME
Luc Darmé, Marco Mancini, Enrico Nardi +1
We discuss the experimental reach of the Frascati PADME experiment in searching for new light bosons via their resonant production in positron annihilation on fixed target atomic e…
Atmospheric resonant production for light dark sectors
Luc Darmé
Cosmic ray atmospheric showers provide an effective environment for the production of MeV-scale dark sector particles. We show that, when available, the resonant annihilation of po…
Exact accidental U(1) symmetries for the axion
Luc Darmé, Enrico Nardi
We study a class of gauge groups that can automatically yield a perturbatively exact Peccei-Quinn symmetry, and we outline a model in which the axion quality problem is solved at a…
An experimental program with high duty-cycle polarized and unpolarized positron beams at Jefferson Lab
A. Accardi, A. Afanasev, I. Albayrak +227
Positron beams, both polarized and unpolarized, are identified as essential ingredients for the experimental programs at the next generation of lepton accelerators. In the context…
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…
