Ground State Decay of the Three-Proton Emitter Na Reveals Isospin Symmetry Breaking
X. -D. Xu, I. Mukha, Z. C. Xu +24
The spectrum of the exotic three-proton (3p) emitter Na has been studied by detecting all in-flight decay products. Derived from the measured angular correlations O+p…
Mass measurements of Yb identify an anomalous proton-neutron interaction
C. L. Brown, J. Ash, B. Ashrafkhani +30
Mass measurements of nuclei can identify structurally-driven trends in binding energy across isotopic chains, and can also isolate specific nucleon-nucleon interactions, such as th…
Hadron Physics Opportunities at FAIR
J. G. Messchendorp, F. Nerling, P. Achenbach +103
This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…
A pathway towards decentralized studies of radioactive post-lead elements and their applications in beyond standard model physics
Moritz Pascal Reiter, Kriti Mahajan, Meetika Narang +21
Molecules have proven to be sensitive tools for studying physics beyond the standard model, with heavy and deformed nuclei offering decisive sensitivity to parity- and time-reversa…
Excitation Spectra of the Reaction near the -Meson Emission Threshold Measured in Coincidence with High-Momentum Protons
R. Sekiya, K. Itahashi, Y. K. Tanaka +74
The missing mass of the reaction has been measured near the -meson emission threshold in coincidence with a high-momentum proton to selectively collect $…
Observation of Tensor-Driven High-Momentum Neutrons in O via () Reactions and Zero-Degree Deuteron Momentum Spectroscopy
X. Wang, H. J. Ong, S. Terashima +42
The reaction has been studied at using 403-, 604-, 907- and 1209-MeV protons, comparing cross sections populating positive- and ne…
