We present a complete analysis of the electric dipole moment (EDM) of the ρ-meson induced by CP violating operators of dimension 4 and 5 within the QCD sum rules approach. The set of CP-odd operators includes the theta term and the electric and chromoelectric dipole moments of the three light quarks. We find that the ρ-meson EDM induced purely by the EDMs of quarks is smaller, but still in reas...

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...

Orbiting EDM has the advantages of superior machining quality over static EDM due to advanced flushing. However, improper tool correction to the relative motion in orbiting EDM will result in dimension errors of the product. As features vary in morphology, tool design for orbiting EDM is a challenging task, particularly for mould comprises assorted features. A strategy for correcting the orbita...

Edit distance with moves (EDM) is a string-to-string distance measure that includes substring moves in addition to ordinal editing operations to turn one string to the other. Although optimizing EDM is intractable, it has many applications especially in error detections. Edit sensitive parsing (ESP) is an efficient parsing algorithm that guarantees an upper bound of parsing discrepancies betwee...

This Study about output parameter of Non Traditional machining, i.e., Which are not used conventionally like Electrical Discharge Machining (EDM) is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques, here it is used for cryogenically treated work piece. In simple terms, EDM is a manufacturing process whereby a desired ...

We present a generalized Schiff transformation on electric dipole moments (EDM) in quantum field theory. By the unitary transformation, the time and parity violating interaction igψ̄σμνγ5ψF μν is transformed into a new form, but its nonrelativistic reduction has a unique form, which is free from Schiff’s theorem. With this operator, we estimate the EDM for the Cs case (dCs) with nonrelativistic ...

The use of unconventional machining techniques in shaping metal matrix composites (MMCs) has generated considerable interest as the manufacturing of complicated die contours. Metal matrix composites are advanced materials having high specific strength, good wear resistance, and high thermal expansion coefficient. Electrical discharge machining is a best process to make complicated shapes on the...

Heavy polar molecules offer a great sensitivity to the electron electric dipole moment (EDM). To guide emerging searches for EDMs with molecular ions, we estimate the EDM-induced energy corrections for hydrogen halide ions HBr(+) and HI(+) in their respective ground X (2)Pi(3/2) states. We find that the energy corrections due to EDM for the two ions differ by an unexpectedly large factor of 15....
