The Implications of 0.5 MeV and 3.5 keV Monochromatic Lines for TGD Based Nuclear Model

Abstract

Monochromatic lines around 0.5 MeV and 3.5-keV X rays have no standard identification. The recent findings exclude the possibility that these particles reside in the conjectured galactic dark matter halo. The detailed consideration of these findings led to an unexpected further progress in TGD based vision about nuclear physics. A correct prediction for the energy of 3.5 eV line emerges and also the 0.5 MeV line is predicted correctly in terms of TGD based nuclear physics. CVC and PCAC hypothesis, M⁸-H duality, and p-adic length scale hypothesis support the view that hadron and nuclear physics could allow a description dual to QCD like picture in terms scaled down weak interaction physics. This picture finds concrete quantitative support. Several p-adic length scales would be involved and the active scale would depend on interaction energy. In particular, a pseudoscalar having interpretation as X boson with mass about 17 MeV is also predicted.
