K0 reconstruction
So called “strange particles” are produced in the proton-proton collisions and decay inside LHCb detector into two other particles reconstructed…
High multiplicity events
A high multiplicity event with three muon tracks (green) recorded on December 12th. Other events can be found here.
More proton-proton collisions
On December 8th many long tracks were reconstructed using the detectors along the whole length of the LHCb. Collision vertex…
RICH rings
LHCb RICH detectors are used to identify particles. The circles show possible position of measured points for different kinds of…
First proton-proton collisions
A proton-proton collision candidate event. On November 23 protons from two beams circulated at LHC and have collided at LHCb.…
First reconstructed pi0’s
pi0 is the short lived particle decaying into two photons which were measured in the electromagnetic calorimeter ECAL. The plot…
First proton interactions
… reconstructed Vertex Locator VELO track. Other reconstructed events can be found here. … event reconstructed later (offline reconstruction). Particularly…
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…
First Cerenkov rings
first (two) rings produced by Cherenkov light emitted by cosmic particles in the two radiators of RICH1 have been observed.…
