Matrix Elements for Fundamental Symmetries — •Javier Menendez — Technische Universität Darmstadt — ExtreMe Matter Institute

Symmetries are crucial for our understanding of Nature and can be tested at low energies with massive detectors. These processes depend on matrix elements that involve both nuclear states, described with state-of-the-art nuclear structure calculations; and hadronic currents, obtained at nuclear energies within chiral effective field theory. Two processes will be reviewed: neutrinoless double-beta (0nbb) decay, and the scattering of weakly interacting massive particles (WIMPs) off nuclei. 0nbb decay violates lepton number conservation and its observation would establish the Majorana nature of neutrinos. WIMPs are predicted in supersymmetric extensions of the Standard Model and are among the most promising candidates for Dark Matter.
