P -odd Eeective Z Interactions
نویسندگان
چکیده
A general analysis of the lowest-dimensional P-odd Z interaction is performed. It turns out that there are only two independent gauge invariant dimension-eight effective Lagrangians of such a type, similarly to the P-even case discussed earlier. It is shown, that such an eeective interaction is naturally induced, at the two-loop level, within an extension of the standard model of electroweak interactions involving two-doublet CP-violating Higgs sector.

Tests of Time Reversal Symmetry in the Deuteron
Internal target experiments with high quality proton beams allow for a new class of experiments providing null tests of time reversal symmetry in forward scattering. This could yield more stringent limits on T-odd P-even observables. A excellent candidate for such experiments is the proton deuteron system. This system is analyzed in terms of eeective T-violating P-conserving nucleon-nucleon int...
متن کاملContact Interactions and High-q 2 Events in E + P Collisions at Hera
We consider eeqq contact interactions as a possible origin of an excess of events above Standard Model predictions in e + p ! e + jet at high Q 2 observed by the H1 and ZEUS collaborations at HERA. The HERA data prefer chirality RL or LR contact terms and atomic physics parity violation measurements severely limit parity-odd contact terms. With equal left-right and right-left chirality interact...

Proton-neutron (p − n) interactions and their various aspects in N ≈ Z nuclei of g 9/2-and f 7/2 subshell are studied using a schematic model interaction with four force parameters proposed recently. It is shown that the model interaction well reproduces observed physical quantities: the double differences of binding energies, symmetry energy, Wigner energy, odd-even mass difference and separat...

متن کاملComputations with Eeective Real Numbers
A real number x is said to be eeective if there exists an algorithm which, given a required tolerance " 2 Z 2 Z , returns a binary approximation x ~ 2 Z 2 Z for x with jx ~ ? xj < ". In this paper, we review several techniques for computations with such numbers, and we will present some new ones.
