Search for solar axions produced through the axion-electron coupling using a new GridPix detector at CAST

K. Altenmüller, V. Anastassopoulos, S. Arguedas-Cuendis +61

We present a search for solar axions produced through the axion-electron coupling using data from a novel 7-GridPix detector installed at the CERN Axion Solar Telescope…

The International Axion Observatory (IAXO): case, status and plans. Input to the European Strategy for Particle Physics

A. Arcusa, S. Ahyoune, K. Altenmuller +120

The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions with unprecedented sensitivity. IAXO holds a unique position in…

An accurate solar axions ray-tracing response of BabyIAXO

S. Ahyoune, K. Altenmueller, I. Antolin +124

BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion heliosc…

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…

Solar chameleons: Novel channels

Tomás O'Shea, Anne-Christine Davis, Maurizio Giannotti +3

We revisit the flux of chameleons (light scalar particles which could play a role in the dark energy phenomenon) produced in the interior of the Sun. Our novel analysis incorporate…

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…
