Detector and data processing technologies for the LHCb experiment: tutorial 47

The Large Hadron Collider beauty (LHCb) experiment [1] at the LHC has been designed and built to search for signs of new physics phenomena beyond the Standard Model of particle physics in the decays of heavy particles made of beauty (b) and charm (c) quarks, created in proton-proton (pp) collisions at the LHC in Geneva, Switzerland. In particular, the LHCb is expected to study the reasons for which matter and anti-matter had different fates just after the initial Big Bang, and now we observe only matter. In fact, all experimental observations point to the conclusion that the current Universe is matter dominated, and there is no evidence of relic anti-matter, which was abundant in the early instants. The violation of CP (combination of Charge and Parity symmetries) is the experimental observation made for the first time in 1964 that particles and anti-particles may behave differently in their decays.
