Search for massive long-lived particles decaying semileptonically at sqrt(s)=13 TeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +996

A search is performed for massive long-lived particles (LLP) decaying semileptonically into a muon and two quarks. Two kinds of LLP production processes were considered. In the fir…
