Webinto a pair of long-lived neutral scalar particles s as shown in Fig. 1. The s-bosons then decay back into SM particles through their mixing with the mediator [15]. The HS model assumes an effective Yukawa coupling between the s-boson and the SM particles; therefore each s-boson decays primarily into a heavy fermion pair: bb¯, cc¯, τþτ−. WebLong-lived particles decaying to e , with masses between 7 and 50GeV/c2 and lifetimes between 2 and 50ps, are searched for by looking at displaced vertices containing …

This paper presents a search for hypothetical massive, charged, long … WebWe examine the capacity of the Large Hadron Collider to determine the mean proper lifetime of long-lived particles assuming different decay final states. We mostly concentrate on the high luminosity runs of the LHC, and therefore, develop our discussion in light of the high amount of pile-up and the various upgrades for the HL-LHC runs.
