Search for the double Dalitz decays $I^\cdot / I^\cdot^{'} \to e^{+} e^{-} I^¼^{+} I^¼^{-}$ and $I^\cdot^{'} \to I^¼^{+} I^¼^{-} I^¼^{+} I^¼^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +653

Using a data sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector, we search for the decays $I^\cdot / I^\cdot^{'} \to e^{+} e^{-} I^¼^{+} I^¼^{-}$ and $Î·' \to Î¼^+Î¼^-Î…

Enhanced $S$ -factor for the $^{14}$ N $(p, I^^{3})^{15}$ O reaction and its impact on the solar composition problem

X. Chen, J. Su, Y. P. Shen +44

The solar composition problem has puzzled astrophysicists for more than 20 years. Recent measurements of carbon-nitrogen-oxygen (CNO) neutrinos by the Borexino experiment show a $\…
