    The BGOOD photoproduction experiment accesses forward meson angles and low momentum exchange kinematics in theudssector, which may be sensitive to molecular-like hadron structure. Recent results are presented, including strangeness photoproduction at forward meson angles, and π0π0coherent photoproduction off the deuteron.

    This report summarizes results of the first lattice QCD calculation of coupled-channelπΣ−K¯Nscattering in the Λ(1405) region. This study was carried out using a single CLS ensemble with a heavier-than-physical pion mass m_π≈ 200 MeV and a lighter-than-physical kaon mass m_K>≈ 487 MeV. Once the finite-volume energy spectrum has been reliably extracted, the Lüscher method was employed to obtain scattering amplitudes. Through a variety of parametrizations of the two-channel K-matrix, the final results show a virtual bound state below the πΣ threshold and a resonance right below K¯N.

    The current three sigma tension in the unitarity test of the Cabbibo-Kobayashi-Maskawa (CKM) matrix is a notable problem with the Standard Model of elementary particle physics. A long-standing goal of the study of free neutron beta decay is to better determine the CKM elementVudthrough measurements of the neutron lifetime and a decay correlation parameter. The Nab collaboration intends to measurea, the neutrino-electron correlation, with accuracy sufficient for a competitive evaluation ofVudbased on neutron decay data alone. This paper gives a status report and an outlook.
