A new upper limit on the axion-photon coupling with an extended CAST run with a Xe-based Micromegas detector

CAST Collaboration, K. Altenmüller, V. Anastassopoulos +62

Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope (CAST) has been searching for…

Background discrimination with a Micromegas detector prototype and veto system for BabyIAXO

K. Altenmüller, J. F. Castel, S. Cebrián +22

In this paper we present measurements performed with a Micromegas X-ray detector setup. The detector is a prototype in the context of the BabyIAXO helioscope, which is under constr…

AlphaCAMM, a Micromegas-based camera for high-sensitivity screening of alpha surface contamination

Konrad Altenmüller, Juan F. Castel, Susana Cebrián +12

Surface contamination of Rn progeny from the U natural decay chain is one of the most difficult background contributions to measure in rare event searches experimen…

First Directional Measurement of sub-MeV Solar Neutrinos with Borexino

M. Agostini, K. Altenmüller, S. Appel +94

We report the measurement of sub-MeV solar neutrinos through the use of their associated Cherenkov radiation, performed with the Borexino detector at the Laboratori Nazionali del G…

Correlated and Integrated Directionality for sub-MeV solar neutrinos in Borexino

M. Agostini, K. Altenmüller, S. Appel +94

Liquid scintillator detectors play a central role in the detection of neutrinos from various sources. In particular, it is the only technique used so far for the precision spectros…

Identification of the cosmogenic C background in large volumes of liquid scintillators with Borexino

M. Agostini, K. Altenmüller, S. Appel +93

Cosmogenic radio-nuclei are an important source of background for low-energy neutrino experiments. In Borexino, cosmogenic C decays outnumber solar and CNO neutrino ev…
