LHCb
The LHCb (Large Hadron Collider beauty) experiment aims to record the decay of particles containing b and anti-b quarks, known as B mesons. The detector is designed to gather information about the identity, trajectory, momentum and energy of each particle.

LHCb Masterclasses

LHCb is part of the International Masterclass Programme: each year, high-school students reach their nearby universities and become LHCb physicists for a day. Their goal is to select in real LHCb events a particular decay of the D0 meson, where a Kaon and a Pion are produced. On such events, the D0 lifetime is measured, using the same analysis tools and techniques LHCb researchers use every day.

LHCb masterclass event files for the event display

Each file contains 30 events recorded with LHCb detector. The events have been pre-selected using loose criteria to contain D0 meson candidates decaying into a Kaon and a Pion.

LHCb event file for real measurement

This file contains about 60k events pre-selected using loose criteria to contain D0 meson candidates decaying into a Kaon and a Pion.
