An intriguing anomaly
Measurement of the decay B0 → D*+τ– ντ [ Branching fraction ratio B0 → D*+τ– ντ/ B0 → D*+μ– νμ = 0.336±0.027±0.030 ] Today, at the 13th Flavor Physics and…
First 13 TeV collisions
Today, proton beams collided at 13 TeV for the first time inside the LHCb detector. The collisions were part of the ongoing accelerator tests, and are not useful for physics…
Observing nearly invisible
Observation of the rare Bs0→μμ decay from the combined analysis of CMS and LHCb data [ Branching fraction Bs0→μμ = (2.8+0.7-0.6)x10-9 ; B0→μμ = (3.9+1.6-1.4)x10-10 ] The CMS and LHCb…
First 2015 proton-proton collisions
Today, for the first time in over two years, protons have collided inside the LHCb detector. Each proton beam had an energy of 450 GeV, which is the value they…
