At high luminosity, bottom, charm and ? factories, synchrotron radiation and lost particles due to beam-gas interaction cause huge backgrounds to detectors, posing problems in trigger rates, radiation damage and efficiency. Studies of such effects have been made and are reported in this book.

CP violation is one of the most subtle effects in the Standard Model of particle physics and may be the first clue to the physics that lies beyond. Charge conjugation, C, and parity, P, are symmetries of particle interactions. C corresponds to the operation of replacing a particle by its antiparticle, while P is the operation of mirror reflection. Before 1956, it was believed that these were also symmetries of the interactions of elementary particles. In 1956, C S Wu found evidence for P violation in the weak interaction. Theorists proposed that the combination of CP would be a symmetry of...
