Among the theoretical models addressing the dark matter problem, the category based on a secluded sector is attracting increasing interest. The PADME experiment, at the Laboratori Nazionali di Frascati (LNF) of INFN, is designed to be sensitive to the production of a low mass gauge boson A’ of a new U(1) symmetry holding for dark particles. This 'dark photon’ is weakly coupled to the photon of...
Abstract: I will show how ultra-high-resolution measurements of the gravitational lensing of the Cosmic Microwave Background (CMB) can be used to measure the small-scale matter power spectrum. A robust measurement of structure on scales below 10 kiloparsecs today (M < 10^9 solar masses) with lensing of the CMB requires a telescope with roughly 20 arcsecond resolution or better, and would...
Abstract: Various theories beyond the Standard Model possess weakly interacting sub-eV particles often referred to as WISPs. Such particles, if they exist, would mediate long-range forces between macroscopic bodies. Strong constraints exist on such ultralight bosons with scalar and vector couplings to fermions from “spin-independent” experiments involving unpolarized test bodies. In contrast,...
