Question:
Consider an integrated luminosity of 100 ev/fb of the BaBar experiment. In the laboratory frame the centre of mass moves with the average Lorentz factor βγ = 0.56. How many seconds at a luminosity L = 1034 cm-2s-1 would be needed to collect such sample? Assuming the value ΔR = 3 at the ϒ(4S) resonance, how many B0B0 pairs have been collected? What is the average separation between production and
decay vertices?
