Today the two halves of new Vertex Locator (VELO) approached the LHC proton-proton collision point for the first time. This process is called “VELO closing” in the LHCb jargon. The…

Start of LHC Run 3. Today, at 16:47, protons collided again at LHCb after a 3.5 year break known as Long Shutdown 2 (LS2). During this period the original LHCb…

One half of the Vertex Locator (VELO) has landed at the LHCb experiment hall. The VELO detector will be located very tightly around the collision point. As the name suggests,…

Yesterday two frames of the scintillating fibre tracker (SciFi) were installed in the detector. They are placed on the other side of the magnet. Together with the VeLo, they will…

First physics results with the HeRSCheL detector. In a typical proton-proton collision at the LHC, proton constituents, quarks or gluons, interact and move to opposite directions. They are interconnected by…

The baccalauréat, often known in France colloquially as le bac, is an academic qualification which French and international students take at the end of the lycée (High School) (secondary education).…

The last run 1 collisions took place at LHCb on February 2013. The proton beams should traverse again LHCb in early 2015. The period in between is called Long Shutdown…

At LHCb the protons collide inside the VErtex LOcator detector (VELO). The VELO is composed of two halves, each consisting of 21 pairs of back-to-back silicon sensors, whose job is…

The physics results presented on this web page were obtained thanks to the excellent LHC collider performance, to the excellent LHCb data acquisition and analysis, and certainly also to the…
