We propose using the storage ring electric dipole moment (EDM) method to search for axion dark matter induced EDM oscillation in nucleons. The uses a combination of $B$ and $E$ fields produce resonance between $g\ensuremath{-}2$ spin precession frequency background field greatly enhance sensitivity it. An range from ${10}^{\ensuremath{-}9}\text{ }\text{ }\mathrm{Hz}$ 100 MHz can, principle, be scanned with high sensitivity, corresponding an ${f}_{a}$ $1{0}^{13}\text{...
Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well those reached directly at high energy colliders. Discrimination between different models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics. In this report, we discuss current status prospects near future a compelling suite such experiments, along with developments needed encompassing theoretical framework.
We consider different types of storage rings as precision probes axion-mediated monopole-dipole forces. show that current and planned experiments aiming to measure magnetic electric dipole moments protons, muons electrons very precisely may explore new parts the parameter space beyond existing laboratory bounds and, in some cases, astrophysical constraints. Remarkably, a light axion coupled explain FNAL/BNL $(g-2)_\mu$ anomaly an environmental effect -- coherent field generated by earth...
The axion, a consequence of the PQ mechanism, has been considered as most elegant solution to strong-CP problem and compelling candidate for cold dark matter. Center Axion Precision Physics Research (CAPP) Institute Basic Science (IBS) was established on 16 October 2013 with main objective launch state art axion experiments in South Korea. Relying haloscope technique, our strategy is run several parallel explore wide range masses sensitivities better than QCD models. We utilize not only...
A hypothetical pseudoscalar particle axion, which is an immediate result of the Peccei-Quinn solution to strong $CP$ problem, may couple gluons and lead oscillating electric dipole moment (EDM) fundamental particles.

This work demonstrates that two systematic errors, coherent betatron oscillations (CBO) and muon losses can be reduced through application of radio frequency (RF) electric fields, which ultimately increases the sensitivity $g-2$ experiments. As ensemble polarized muons goes around a weak focusing storage ring, their spin precesses, when they decay interaction, $\mu^+ \rightarrow e^+ \nu_e \bar{\nu_\mu}$, positrons are detected by electromagnetic calorimeters. In addition to expected...

본 논문은 스펙트럴 영역에서 마이크로스트립 선로의 접지면에 있는 DGS 슬롯의 임피던스 특성을 구하고, 이를 스텝 저역 통과 필터 특성 개선에 응용하였다. 슬롯 해석에 사용한 방법은 슬롯에 의한 불연속으로 인한 전압과 self-reaction을 이용한 방법이다. 이 방법을 수치 해석 결과는 full-wave 방법의 결과와 비교해도 정확하다는 것을 보였다. 그리고 기존 필터의 주파수 개선하기 위해서, 균일한 또는 비균일한 슬롯을 갖는 필터를 설계 제작하였다. 실험 결과를 통해, 제안된 필터는 필터보다 차단 대역이 넓어지고 차단주파수 이후 급격한 특성과 같은 개선된 확인할 수 있었다. In this paper, investigations on the impedance characteristics of a DGS(Defected Ground Structure) slot in groud plane microstripline are presented spectral domain and...
