Neutron Electric Dipole Moment Experiments
The possibility of a non-zero value for neutron EDM continues to be of central importance in physics and cosmology. A non-zero neutron EDM would be a direct evidence for time-reversal symmetry violation. It also implies CP-violation under the assumption of CPT invariance. To date, only two examples of CP-violation have been found: decays of neutral K mesons and B mesons. CP-violation is believe...
متن کاملThe 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...
متن کاملNeutron Electric Dipole Moment Experiment
A.1.a General Introduction Precision measurements of the properties of the neutron present an opportunity to search for violations of fundamental symmetries and to make critical tests of the validity of the Standard Model (SM) of electroweak (EW) interactions. These experiments have been pursued with great energy and interest since Chadwick [i] discovered the neutron in 1932. Searches for the e...
متن کاملFuture Muon Dipole Moment Measurements
From the famous experiments of Stern and Gerlach to the present, measurements of magnetic dipole moments, and searches for electric dipole moments of “elementary” particles have played a major role in our understanding of sub-atomic physics. In this talk I discuss the progress on measurements and theory of the magnetic dipole moment of the muon. I also discuss a new proposal to search for a per...
متن کاملEnhanced enantioselectivity of 3-methylcyclohexanone by mixed diol host compounds.
3-Methylcyclohexanone is only partially resolved by crystallisation with a chiral diol host compound (ee 40%), but when recrystallised from an equimolar mixture of the chiral diol host and a similar but achiral host we obtain complete resolution. The latter host acts as a nucleation inhibitor and the enhanced resolution is attributed to kinetic effects.
