    The proton-proton momentum correlation functions () for kinematically complete decay channels of Al p + p + Na and Mg p + p + Ne have been measured at the RIKEN RI Beam Factory. From the very different correlation strength of for Al and Mg, the source size and emission time information were extracted from the data by assuming a Gaussian source profile in the correlation function calculation code (CRAB). The results indicated that the mechanism of two-proton emission from Al was mainly sequential emission, while that of Mg was mainly three-body simultaneous emission. By combining our earlier results of the two-proton relative momentum and the opening angle, it is pointed out that the mechanism of two-proton emission could be distinguished clearly.

    On neutrinoless double electron capture

    E. G. Drukarev · A. I. Mikhailov

    We found the probability for the neutrinoless double electron capture in the case of capture. We clarified the mechanism of the energy transfer from the nucleus to the bound electrons. This enabled us to obtain the equations for the probability of the process which modify those obtained earlier. We found that the probability of the process is three orders of magnitude larger than it was supposed earlier.

    Single-Transverse-Spin-Asymmetry studies with a fixed-target experiment using the LHC beams (AFTER@LHC)

    J.P. Lansberg🇫🇷 · M. Anselmino🇮🇹 · R. Arnaldi🇮🇹 · S.J. Brodsky🇺🇸 · V. Chambert🇫🇷 · C. Da Silva🇺🇸 · J.P. Didelez🇫🇷 · M.G Echevarria🇪🇸 · E.G. Ferreiro🇪🇸 · F. Fleuret🇫🇷 · Y. Gao🇨🇳 · B. Genolini🇫🇷 and 25 other authors

    We discuss the potential of AFTER@LHC to measure single-transverse-spin asymmetries in open-charm and bottomonium production. With a HERMES-like hydrogen polarised target, such measurements over a year can reach precisions close to the per cent level. This is particularly remarkable since these analyses can probably not be carried out anywhere else
