Direct detection of solar chameleons with electron recoil data from XENONnT
Guan-Wen Yuan, Anne-Christine Davis, Maurizio Giannotti +3
We reassess prospects for direct detection of solar chameleons, in light of recent progress in modeling their production, and the availability of new XENONnT data. We show that the…

Primordial regular black holes as all the dark matter. III. Covariant canonical quantum gravity models
Marco CalzÃ, Davide Pedrotti, Guan-Wen Yuan +1
In earlier companion papers, we showed that non-singular primordial black holes (PBHs) could account for all the dark matter (DM) over a significantly wider mass range compared to…

Machine Learning-Based Analytical Expressions for Gray-Body Factors and Application to Primordial Black Holes
Guan-Wen Yuan, Marco CalzÃ, Davide Pedrotti
Symbolic Regression (SR) is a machine learning approach that explores the space of mathematical expressions to identify those that best fit a given dataset, balancing both accuracy…
