Electric dipole moment in storage ring experiments

چکیده
The measurement of electric dipole moment in storage rings can potentially exceed the sensitivity tests with neutral systems. spin dynamics under such conditions is described by Bargmann-Michel-Telegdi equation. It be derived semiclassical approximation several assumptions one which zero pseudoscalar bilinear. However, many promising extensions to standard model consider scalar-pseudoscalar couplings assume nonzero electron pseudoscalar. We re-derive precession equation that do not zero. leads a correction term might required for matching ring measurements QFT evaluations.

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 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 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 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...
