First reconstructed pi0’s
pi0 is the short lived particle decaying into two photons which were measured in the electromagnetic calorimeter ECAL. The plot above shows the nearly perfectly reconstructed pi0 mass.

A splash from the LHC beam
LHC has restarted on November 21st. Two LHC beams have made a full turn of the LHC. Afterwards, after synchronization with the LHC accelerating system (RF capture in technical language),…
First Cerenkov rings
first (two) rings produced by Cherenkov light emitted by cosmic particles in the two radiators of RICH1 have been observed. See explanations

LHCb catches a glimpse of the LHC beam
Computer images of the first beam through beam through LHCb (see video on YouTube or CERN CDS) The LHC’s anti-clockwise beam transfer system was tested over the weekend June 6-7,…
Angels and Demons
In the movie Angels and Demons the Illuminati have stolen antimatter from CERN in order to destroy Vatican. But what is antimatter? Is is real? Is it dangerous? What is…
Nobel Prize in Physics
Laureates: Yoichiro Nambu, Makoto Kobayashi, Toshihide Maskawa.The LHCb Collaboration is deeply grateful to the laureates for having prepared a precise theoretical framework in which we will try to understand why…
First beam day
As the beam of protons made its first full circuit of the LHC, the experiment’s detectors recorded the exciting moment: the cherenkov detectors RICH1 and RICH2, the muon chambers and…
