Axions are the result of a dynamic field, similar to Higgs field, invented to solve the so-called Strong CP-problem, i.e., why the electric dipole moment (EDM) of the neutron and proton has not been observed so far even though the theory of QCD requires otherwise. Axions as dark matter can be thought of as an oscillatory field interacting extremely weakly with normal matter other than...
The Center for Axion and Precision Physics Research (CAPP) at IBS is establishing a state-of-the-art axion experiment in Korea to search for relic axion particles converting to microwave photons in a resonant cavity submerged in a strong magnetic field. The initial stage of building our axion experiment, CULTASK (CAPP Ultra Low Temperature Axion Search in Korea) is completed at KAIST (Korea...
Neutrino physics is one of the most active fields in the modern nuclear and particle physics. All the mixing angles and mass differences are measured with the solar, the reactor, and the accelerator driven neutrino oscillation experiments. Yet, the mass of the lightest neutrino is not known and whether the neutrinos are Dirac or Majorana particles, is also not determined. Neutrino-less double...
Astrophysical observations give overwhelming evidence for the existence of dark matter. The DAMA collaboration has asserted for years that they observe a dark matter-induced annual modulation signal in their NaI(Tl)-based detectors, while other direct detection dark matter experiments have seen no indications of a signal. I will describe the current status and prospect for alternative...
