We report the results of the first computation related to the study of the spectator effects in the rare decay mode B→Kγγ within the framework of Standard Model. It is found that the account of these effects results in the enhancement factor for the short-distance reducible contribution to the branching ratio.

This paper summarises the B-physics prospects of the LHCb experiment. The focus is on the uniqueness of LHCb over and above the B-factories and the Tevatron experiments: the measurement of the unitarity angle γ using a number of complementary methods, the measurement of the [Formula: see text] mixing phase φs in tree and penguin decay modes, and the expected observation of the rare decay mode [Formula: see text] below Standard Model predictions.

While studying the heavy fragments (Z ≥ 4) emitted from the disintegrations of silver and bromine nuclei by 5GeV/c antiprotons in nuclear emulsion, an event was found to have the decay characteristics of 8He in its rare decay mode, [Formula: see text].
