Abstract: We explored a distinct mechanism for matter creation via electron–positron pair production during bound–bound transitions in the deexcitation of muonic atoms. For ions with nuclear charges Z ⩾ 24, transitions from low-lying excited states to… read more here.

Abstract: Resonant electron–positron pair production by a high-energy gamma quantum ωi≳102 GeV in the field of a nucleus and a quasi-monochromatic laser wave with the intensities I≲1016 – 1017 Wcm−2 was theoretically studied. Under the resonant condition, an… read more here.

DOI: 10.3390/universe10040168
Abstract: We have repeated the experiment performed recently by ATOMKI Laboratory (Debrecen, Hungary), which may indicate a new particle called X17 in the literature. In order to obtain a reliable and independent result, we used a… read more here.
