The Role of Ab Initio Beta-Decay Calculations in Light Nuclei for Probes of Physics Beyond the Standard Model

Grigor H. Sargsyan, Garrett B. King, Ayala Glick-Magid +1

Precision beta decay experiments serve as powerful probes of physics beyond the Standard Model, enabling stringent tests of fundamental symmetries of nature. In particular, these e…

Constraining Hamiltonians from chiral effective field theory with neutron-star data

Cassandra L. Armstrong, Brendan T. Reed, Tate Plohr +4

Multi-messenger observations of neutron stars (NSs) and their mergers have placed strong constraints on the dense-matter equation of state (EOS). The EOS, in turn, depends on micro…

Active learning emulators for nuclear two-body scattering in momentum space

A. Giri, J. Kim, C. Drischler +2

We extend the active learning emulators for two-body scattering in coordinate space with error estimation, recently developed by Maldonado et al. [Phys. Rev. C 112, 024002], to cou…

From closed shells to open shells: Coupled-cluster calculations of atomic nuclei
