The storage ring EDM method can be used to study the electron EDM at the 10^-29 e.cm level provided there is a high sensitivity electron spin polarimeter available at 15 MeV/c, the electron magic momentum. In this study, we present the feasibility results on a polarimeter concept we developed specifically for the storage ring electron EDM measurement. The idea of using Compton backscattering...

The Weakly Interacting Massive Particles, which appear in supersymmetric extensions of the Standard Model, are one of the strongest candidates to form the Dark Matter of the Universe. The lack of a positive signal during the last 30 years in the search of “standard WIMPs“, during which the experimental efforts have reached remarkable levels of sensitivity, and the lack of proof of...

We present a proposal to search for QCD axions with mass in the 200 μeV range, assuming that they make a dominant component of dark matter. Due to the axion–electron spin coupling, their effect is equivalent to the application of an oscillating rf field with frequency and amplitude fixed by the axion mass and coupling respectively. This equivalent magnetic field would produce spin flips in a...

We can consider two continuous parameters, one is the MI-axion direction
and the other the phase of anomalous U(1) gauge transformation. If the anomalous U(1) gauge boson obtains mass by absorbing the MI-axion at the compactification scale, one continuous parameter remains, which describes a global symmetry. This corresponds to the 't Hooft mechanism in gauge theory that if one scalar VEV...

I will present some recent results on the Fermi-LAT and Nustar potential to probe axion like particles (ALPs) produced in stars. The case of massive ALPs will also be included.
