“…T2K/Hyper-Kamiokande The T2K experiment [102], located in Japan, is sensitive to numerous models, taking benefit of the J-PARC neutrino facility, the composite near detector complex and the well established water Cherenkov technology for the far detector (Super-Kamiokande up to ∼ 2026, and Hyper-Kamiokande -HK-from then). In particular, a recent study has estimated the future sensitivity of T2K and HK to millicharged particles [205]. Pairs of mCP would be produced in meson decays alongside with neutrinos.…”

“…In recent years, more attention has been given to these so-called millicharged particles (MCP) in the MeV-GeV mass regime. Searches for this scenario have been proposed for beam-based neutrino experiments [20,21] and for dedicated experiments situated near accelerator complexes [22][23][24][25][26][27]. Existing data have been reanalyzed in this context in refs.…”

For nearly a century, studying cosmic-ray air showers has driven progress in our understanding of elementary particle physics. In this work, we revisit the production of millicharged particles in these atmospheric showers and provide new constraints for XENON1T and Super-Kamiokande and new sensitivity estimates of current and future detectors, such as JUNO. We discuss distinct search strategies, specifically studies of single-energy-deposition events, where one electron in the detector receives a relatively large energy transfer, as well as multiple-scattering events consisting of (at least) two relatively small energy depositions. We demonstrate that these atmospheric search strategies — especially the multiple-scattering signature — provide significant room for improvement beyond existing searches, in a way that is complementary to anthropogenic, beam-based searches for MeV-GeV millicharged particles. Finally, we also discuss the implementation of a Monte Carlo simulation for millicharged particle detection in large-volume neutrino detectors, such as IceCube.

Light millicharged particles can be copiously produced from meson decays in cosmic ray collisions with the atmosphere, leading to detectable signals in large underground neutrino detectors. In this paper we study a new channel for generating atmospheric millicharged particles, the proton bremsstrahlung process. We find that the proton bremsstrahlung process leads to a significantly higher flux of millicharged particles compared to meson decays and, for certain masses, results in a one-order-of-magnitude improvement in the flux. Consequently, Super-K constraints on ε2 for sub-GeV MCPs are improved by half order of magnitude. We further note that the study on the proton bremsstrahlung process can be extended to a variety of new physics particle searches in atmospheric collisions and in low energy proton accelerators.
