Yet it was Hopkins (1912) who first realized the full significance of vitamins...
متن کاملPresent Status of the Kekb B-factory
The KEKB B-factory is an energy-asymmetric e+edouble-ring collider at KEK. It has been operated since December 1998, and has recently marked the peak luminosity of 7.35 /nb/s which is the highest value in the history of colliders. By several improvements such as solenoid windings in LER, new moving-chamber masks in HER, etc., the luminosity performance of KEKB has been significantly upgraded la...
متن کاملPresent Status of Inclusive Rare B Decays
We give a status report on inclusive rare B decays, highlighting recent developments and open problems. We focus on the decay modes B → Xs,dγ, B → Xsll and B → Xsνν̄ and on their role in the search for new physics. Most of the inclusive rare B decays are important modes of flavour physics due to the small hadronic uncertainties. They can be regarded as laboratories to search for new physics. We ...
