"The neutrino magnetic moment (NMM) in the Standard Model, minimally extended\r\nallowing for massive neutrinos, is many orders of magnitude below current and expected\r\nexperimental sensitivities. A potential measurement would therefore strongly\r\nhint to new physics beyond the Standard Model. It raises the question how a positive\r\nNMM signal in future experiments could be explained in a theoretically consistent\r\nway. After a brief theoretical introduction, we summarize existing experimental\r\nbounds and systematically analyze the possibilities of model building for accommodating\r\nlarge NMMs in beyond the Standard Model frameworks. As a by-product, we\r\nderive new limits on millicharged particles from the non-observation of NMMs. The\r\ntight connection of NMMs and neutrino masses generically leads to a fine-tuning\r\nproblem in typical models that predict sizable NMMs. We explicitly demonstrate\r\nthis problem using a model in which NMMs are proportional to neutrino masses.\r\nFinally, we investigate mechanisms that provide large NMMs and at the same time\r\navoid the fine-tuning problem. As a result, we find only two such mechanisms that\r\nare not yet excluded and in which large transition magnetic moments can be realized\r\nfor Majorana neutrinos only."^^ . "2017" . . . . . . .
