Here we report progress toward the measurement of a permanent electric dipole moment (EDM) in hyperpolarized liquid 129Xe which violates invariance under both parity and time reversal. The standard model (SM) predicts atomic EDMs well beyond current experimental limits while many natural extensions to the SM predict EDMs within the expected sensitivity of current experiments. Hence the search f...

Searches for CP-violating effects in atoms and molecules provide important constrains on competing extensions to the standard model of elementary particles. In particular, CP violation in an atom leads to the CP-odd T,P-odd polarizability CP: a magnetic moment CP is induced by an electric field E0 applied to an atom, CP= E0. We estimate the CP-violating polarizability for rare-gas diamagnetic a...

In Electrical Discharge Machining, oxides (or debris) are created and accumulated in the sparking gap between an electrode and a work piece. If the debris density becomes too great in certain points in the gap, there is a reduction in the resistance, which encourages the formation of abnormal discharges, results in significant electrode damage and slows down the material removal rate. To enhanc...

The matrix, 8-component Dirac-like form of P -odd equations for boson fields of spins 1 and 0 are obtained and the GL(2, c) symmetry group of equations is derived. We found exact solutions of the field equation for vector particles with arbitrary electric and magnetic moments in external constant and uniform electromagnetic fields. The differential probability of pair production of vector parti...

Fabrication of photoluminescent n-type porous silicon (nPS), using electrode-assisted lateral electric field accompanied with a perpendicular magnetic field, is reported. The results have been compared with the porous structures fabricated by means of conventional anodization and electrode-assisted lateral electric field without magnetic field. The lateral electric field (LEF) applied across th...

Symmetries of the Universe have always provided theoreticians with a powerful tool in their efforts to understand and unify physics laws. Three of them have shaped physics over the last 50 years: parity (P ), charge conjugation (C), and time-reversal (T ). Today, T -violation remains the most mysterious symmetry violation as it is not understood properly and as much stronger T -violating mechan...

Complete two-loop electroweak corrections to leptonic anomalous magnetic moments have been calculated recently using asymptotic expansions of Feynman diagrams. Techniques developed in that context can also be applied to the electric dipole moments (EDM) of fermions. In the Standard Model the EDM was proved to vanish at two loops. In this talk we discuss a simplification of that proof.

A study on ultrasonic vibration-assisted electrical discharge machining (UVEDM) micro-hole, which mainly includes three key designs, was conducted to improve the performance of electric (EDM) micro-holes TC4 titanium alloy. First, a mathematical model for velocity flow field in interelectrode gap established. Consequently, effect presence or absence vibration analyzed. Furthermore, based COMSOL...

In an effective lagrangian approach [1] to new physics, the authors in ref. [2] pushed tau anomalous magnetic and electric dipole moments (AMDM and EDM) down to 10−11 and 10−25 e cm by using a Fritzsch-Xing lepton mass matrix ansatz. In this note, we find that, in this approach, there exists the connection between τ AMDM and EDM and the lepton flavor mixing matrix. By using the current neutrino...

Of the various schemes described in an earlier version of this report for measuring the electric dipole moment (EDM) of the electron at Wilson Lab, only one survives as a realistic candidate. (One of the discarded schemes had been investigated earlier by Orlov et al.[12] for protons and shown not to work.) The proposed ring uses a 14.5MeV electron beam in an allelectric ring with resonant longi...
