PARTICLE PHYSICS SEMINAR
at 17:00 – Stückelberg Auditorium
Long-lived particle searches at colliders
Dr. Philippe Mermod / Oxford University
The discovery of exotic long-lived particles would address a number of important questions in modern physics such as the origin and composition of dark matter and the unification of the fundamental forces. This talk will focus on searches for long-lived charged massive particles, where "charged" refers to the magnetic, electric or colour charge. Previous searches at the LEP and Tevatron Colliders allowed to put mass and cross section limits on various kinds of long-lived particles, such as Magnetic Monopoles and metastable leptons and up-type quarks. The new energy regime made available at the LHC will probe physics regions well beyond these limits. For instance, a new long-lived particle with mass 300 GeV carrying colour charge is expected to be copiously produced at the LHC and leave striking events in the detectors. I will outline a signature-based search strategy for long-lived massive hadrons in early ATLAS data
