LHCb

The LHC accelerator will accelerate particles to the highest energy ever achieved in a laboratory. The LHCb detector will register the collisions between these particles, in particular collisions between pairs of anti-beauty and beauty quarks. It will record billion pairs of anti-beauty and beauty per year extremely precisely. Its goal: to detect a bigger asymmetry that will help explain how it is that nature prefers matter to antimatter.arrowMore about the Physics of LHCb

Despite being very big and heavy, the LHCb detector is a high-precision instrument based on the latest cutting-edge technology. The size comes from that fact that, at a closer look, it actually consists of several different types of sub-detectors, each one specialized in measuring a different aspect of what happens in the particle collisions. As a whole, the detector provides information about the trajectory, the identity, the momentum and the energy of each particle produced in the collisions. Each sub-detector is also very big in order to make precise measurements of the extremely fast and energetic particles that are produced.
