Search for an electric dipole moment of the neutron
The result of a search for the electric dipole moment of the neutron is presented. A short review of past experimental work and theoretical predictions introduces a discussion of the experimental method used in, and the results obtained by, the present work. The weighted mean of three separate groups of data gives (+0.4 + 1.5) X 10 "cm for the neutron's electric dipole moment. We conclude that ...
متن کاملSearch for a Neutron Electric Dipole Moment
The possible existence of a nonzero electric dipole moment (EDM) of the neutron is of great fundamental interest in itself and directly impacts our understanding of the nature of electro-weak and strong interactions. The experimental search for this moment has the potential to reveal new sources of T and CP violation and to challenge calculations that propose extensions to the Standard Model. T...
متن کاملCompact storage ring to search for the muon electric dipole moment
We present the concept of a compact storage ring of less than 0.5 m orbit radius to search for the electric dipole moment of the muon (dμ) by adapting the “frozen spin” method. At existing muon facilities a statistics limited sensitivity of dμ ∼ 5 × 10 e cm can be achieved within one year of data taking. Reaching this precision would demonstrate the viability of this novel technique to directly...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولThe Muon Electric Dipole Moment
The electric dipole moment of the muon (dμ) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For tan β ≡ |v2|/|v1| ∼ 1, contributions from two loop diagrams involving the t quark and the W boson dominate; while for tan β ∼ > 10, contributions from two loop diagrams involving the b quark and the τ lepton are dominant. For 8 ∼ > tan β ∼ > 4, significant cancellati...
