Description
In this paper, we study the prospect of ECAL barrel timing to develop
triggers dedicated to long-lived particles decaying to jets, at the level-1 of
HL-LHC. We construct over 20 timing based variables, and identify two of them
which have better performances and are robust against increasing PU. We
estimate the QCD prompt jet background rates accurately using the "stitching"
procedure for varying thresholds defining our triggers, and compute the signal
efficiencies for different LLP scenarios for a permissible background rate. The
trigger efficiencies can go up to O(80%) for the most optimal
trigger for pair-produced heavy LLPs having high decay lengths, which degrades
with decreasing mass and decay length of the LLP. We also discuss the prospect
of including the information of displaced L1 tracks to our triggers, which
further improves the results, especially for LLPs characterised by lower decay
lengths.
