Fundamental Physics in Small Experiments

Synergy between NP and HEP research goals and efforts in fundamental symmetries and interactions

“…The 2021 Snowmass process brought to the fore a remarkable collaboration between nuclear and high energy physicists to elucidate the potential for significant progress through joint experimental and theoretical efforts in four areas of great interest to the "Fundamental Symmetries" subprogram of the DOE Office of Science, Nuclear Physics. This collaboration is evident from the joint authorship of four contributions [1][2][3][4], including the associated topical group reports [5][6][7]. These four areas are: (i) neutrinoless double beta decay (0νββ), (ii) the neutron electric dipole moment (nEDM), (iii) tests of CKM unitarity through precision calculations for the extraction of the V ud matrix element, and (iv) lepton-nucleus scattering.…”
