The results of preliminary background measurements at a small depth of 5 mwe with a dedicated spectrometer built at ITEP are reported. We recalculate the magnetic moment of neutrinos in a hot and dense medium. PHYSICAL REVIEW LETTERS, 2002 Muon anomalous magnetic moment from. These estimates place specific requirements on the design of the spectrometer. IceCube events from heavy DM decays through the right-handed neutrino portal. Title: Neutrino Magnetic Moment and the Process e rightarrow e Authors: J. The properties of the so-far existing low-background Ge spectrometers are discussed, and additional sources of background in a reactor experiment at a small depth are estimated. The results of preliminary background measurements at a small depth of 5 mwe with a dedicated spectrometer built at ITEP are reported.ĪB - We analyze the possibility of using a low-background Ge-NaI spectrometer in a reactor experiment aimed at searches for the neutrino magnetic moment down to 3 × 10-11 of the electron magneton. Medium modifications of nucleon form factors After defining neutrino form factors, here we present the nucleon electroweak form factors in free-space and medium. The total inelastic cross section is given. Neutrino magnetic moment ( MM) is an important property of massive neutrinos. But if the neutrino is a Dirac particle, this change of helicity makes the neutrino a right handed one and thus it will be a sterile neutrino. 5.1), only the Dirac neutrino can have a magnetic moment. A formula for the stopping power of matter for neutrinos is derived and applied to the study of the solar neutrino anomaly. If a neutrino has a non-vanishing magnetic moment, it experiences a rotation of its spin in the presence of a magnetic eld which has a componentperpendicularto the direction of motion to the neutrino. Abstract From the general argument (see Sect. These estimates place specific requirements on the design of the spectrometer. The value of the neutrino magnetic moment is estimated around 10 10 B as in Refs. neutrinos interacting via their magnetic moment with electrons. For neutrinos with a magnetic moment, we calculate the production rate of right handed neutrinos in a hot and dense plasma via the quirality flip (LR). N2 - We analyze the possibility of using a low-background Ge-NaI spectrometer in a reactor experiment aimed at searches for the neutrino magnetic moment down to 3 × 10-11 of the electron magneton.
