1.2 TeV collisions at LHCb
On December 14th 1.2 TeV proton beams have collided at LHCb during LHC machine studies. Many LHCb subdetectors, except for sensitive silicon detectors, recorded the world’s highest energy pp collisions.…
proton interactions with gas
Position of proton interactions inside the vertex detector with residual gas are shown in blue or red, proton-proton interactions in green (more details).
K0 reconstruction
So called “strange particles” are produced in the proton-proton collisions and decay inside LHCb detector into two other particles reconstructed as red tracks (more details).
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 is clearly observed (bottom left). The tracks are curved in…
RICH rings
LHCb RICH detectors are used to identify particles. The circles show possible position of measured points for different kinds of particles traversing the detector. The measured points clearly choose one…
