Conclusions ï® ï® ï® ï® ï® ï® ï® ï® Long-lived particles are very common in the theoretical literature The Hidden Valley scenario illustrates that we may have underestimated the likelihood of long-lived particles. HV dynamics also can lead to a high multiplicity (per event) of such particles Tevatron experiments have not been able to put strong limits on long-lived neutral particles decaying in flight ATLAS/CMS will not find it easy in many cases due to ï± Triggering limitations ï± Reconstruction challenges LHCb therefore may have a special opportunity to discover new physics HLT1 and secondary interactions appear to be the bottleneck Theorists are available to provide benchmark models, MC assistance LHCb May 2009 M J Strassler 21
