The LPC has transformed the way the CMS collaboration educates young students and post-docs CMS Data Analysis School established at the LPC for new collaborators The LPC hosts distinguished visiting scientists and fosters interactions with off-site collaborators and theorists through seminars, workshops, and hands-on tutorials. The LPC is the local (US) center of excellence for CMS physics The LPC serves as a critical link for remote physicists to participate directly in the CMS experiment effectively, economically and transparently.
