Recently, the LHCb collaboration reported the first evidence for the decay B08 →μ＋μ-. A branching ratio of （B08 →μ＋μ-） = （3.2＋1.5-1.2） x 10-9 is given.

A branching ratio of （B08 →μ＋μ-） = （3.2＋1.5-1.2） x 10-9 is given. Using the newest data, and together with the most precise predictions of the Standard Model contributions to the decay, we derive the constraints on the combinations of the R-parity violating parameters. Our results are several orders of magnitudes stronger than the constraints in the previous literature. We also update the constraints on the relevant parameters using the upper limit of B（B08 →μ＋μ-）.展开更多

The base of third metacarpal was found to be fractured with comminution of the capitate. The decrease in carpal height index and comminution of the third metacar- pal base lead to dilemma between conservative treatment and surgical management of this particular injury. The sur- gical management was chosen to maintain the carpal height index of the wrist to prevent the late degenerative changes.The patient was applied with external fixator in distraction mode expanning the wrist joint for six weeks, and the wrist was mobilised after removal of the fixator. It is shown that the external fixator in distraction mode expanning the wrist joint is a good alternative method for treatment of capitate fracture.展开更多
