Directional detection of Dark Matter particles in the MeV mass range could be accomplished by studying electron recoils in large arrays of parallel carbon nanotubes. In a scattering process with a lattice electron, a DM particle might transfer sufficient energy to eject it from the nanotube surface. An external electric field is added to drive the electron towards the open ends of the array,...
In Particle Physics, axions appear in very well motivated extensions of the Standard Model including the Peccei-Quinn mechanism proposed to solve the long-standing strong-CP problem. Together with the weakly interacting massive particles of supersymmetric theories, axions are also a favored candidate for resolving the Dark Matter issue.
I propose a new detection scheme for the search of...
For many years the PVLAS collaboration has been working on trying to measure vacuum magnetic birefringence using optical techniques. That electrodynamics in vacuum is non-linear was predicted in 1935 [H. Euler and B. Kockel, Naturwiss, 23, 246 (1935)] and the first experimental proposal to detect the leading nonlinear effect, namely vacuum magnetic birefringence closely related to...
