Search for exotic long-lived particles at CLIC
M. Kucharczyk, M. Goncerz

TL;DR
This paper evaluates the sensitivity of the CLIC ILD detector to detect long-lived particles from Higgs decays at different energies, covering various masses and lifetimes, and estimates the production cross-section limits.
Contribution
It presents the first detailed sensitivity study of CLIC for long-lived particles from Higgs decays at multiple energies and luminosities.
Findings
Sensitivity to long-lived particles with lifetimes from 1 to 300 ps.
Mass range sensitivity between 25 and 50 GeV.
Cross-section limits as a function of mass and lifetime.
Abstract
A study of the sensitivity of the CLIC ILD detector model for massive long-lived particles produced in the decay of the Higgs boson is presented, using a data sample of collisions at centre-of-mass energy of 350 GeV and 3 TeV, corresponding to an integrated luminosity of 1 ab-1 and 3 ab-1, respectively. The sensitivity range covers long-lived particle lifetimes from 1 to 300 ps, masses between 25 and 50 GeV, and a parent Higgs mass of 126 GeV. Sensitivities to the production cross-section as a function of the long-lived particle mass and lifetime are determined.
