Exploring the Sun's core with BabyIAXO
Javier Galan
Axions are a natural consequence of the Peccei-Quinn mechanism, the most compelling solution to the strong-CP problem. Similar axion-like particles (ALPs) also appear in a number o…
PandaX-III: Searching for Neutrinoless Double Beta Decay with High Pressure Xe Gas Time Projection Chambers
Xun Chen, Changbo Fu, Javier Galan +67
Searching for the Neutrinoless Double Beta Decay (NLDBD) is now regarded as the topmost promising technique to explore the nature of neutrinos after the discovery of neutrino masse…
Probing the axion-nucleon coupling with the next generation of axion helioscopes
Luca Di Luzio, Javier Galan, Maurizio Giannotti +8
A finite axion-nucleon coupling, nearly unavoidable for QCD axions, leads to the production of axions via the thermal excitation and subsequent de-excitation of Fe-57 isotopes in t…
Overview and design optimization of a custom hybrid X-ray telescope for the International Axion Observatory (IAXO)
Yue Yu, Jooyun Woo, Ipek Altunyurt +34
We present the design optimization for maximizing the effective area of a custom X-ray optic for the International Axion Observatory (IAXO) and BabyIAXO, including its novel hybrid…
Production of axion-like particles from photon conversions in large-scale solar magnetic fields
Ersilia Guarini, Pierluca Carenza, Javier Galan +2
The Sun is a well-studied astrophysical source of axion-like particles (ALPs), produced mainly through the Primakoff process. Moreover, in the Sun there exist large-scale magnetic…
Design and commissioning of a 600 L Time Projection Chamber with Microbulk Micromegas
Heng Lin, Denis Calvet, Lei Chen +23
We report the design, construction, and initial commissioning results of a large high pressure gaseous Time Projection Chamber (TPC) with Micromegas modules for charge readout. The…
Extending axions searches with a spherical TPC
Javier Galan, Gilles Gerbier, Ioannis Giomataris +2
We present the prospects for detection of KK-axions using a large volume spherical TPC through natural decay to two gammas. The higher excited mass states of this axion model allow…
Axion search with BabyIAXO in view of IAXO
Javier Galan
Axions are a natural consequence of the Peccei-Quinn mechanism, the most compelling solution to the strong-CP problem. Similar axion-like particles (ALPs) also appear in a number o…
