Neutrino decay of positronium in the standard model and beyond

Primary tabs

Govaerts, Jan [UCL] Van Caillie, Marc

(eng) Whether in the Standard Model or beyond it, neutrinos contribute to the invisible decay mode of orthopositronium but practically not at all to that of parapositronium. Although this remark does not resolve the orthopositronium decay puzzle, it allows for upper bounds to be set on neutrino magnetic moments. Comment: 10 pages, LateX file
