We have studied Bs0→Ds-π+ and Bs0→Ds K± decays using 23.6fb-1 of data collected at the Υ(5S) resonance with the Belle detector at the KEKB e+e- collider. This highly pure Bs0→Ds-π+ sample is used to measure the branching fraction, B(Bs0→Ds-π+)=[3.67-0.33+0 ...
High energy accelerators and storage rings are designed to collide charged particle beams and study their collision products. The production rate of the collision products has to be maximized in order to reduce the statistical uncertainty of the produced e ...
A particle beam is a collection of a large number of charges and represents an electromagnetic potential for other charges, therefore exerting forces on itself (space charge) and other beams (Beam-Beam Interactions, BBIs). The control of the BBIs in partic ...
Recently it has been pointed out that the characteristic quantum-gravity scale could be as low as the weak scale in theories with gravity propagating in higher dimensions. The observed smallness of Newton's constant is a consequence of the large compactifi ...
The CERN Large Hadron Collider (LHC) will store 2808 bunches per colliding beam, each bunch consisting of 1011 protons at an energy of 7 TeV. If there is a failure in an element of the accelerator, the resulting beam losses could cause damages not only to ...
