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