Abstract
A search is performed for heavy long-lived
charged particles using 3.0 fb−1 of proton–proton collisions
collected at √s = 7 and 8 TeV with the LHCb detector. The
search is mainly based on the response of the ring imaging
Cherenkov detectors to distinguish the heavy, slow-moving
particles from muons. No evidence is found for the production
of such long-lived states. The results are expressed as
limits on the Drell–Yan production of pairs of long-lived particles,
with both particles in the LHCb pseudorapidity acceptance,
1.8 <η< 4.9. The mass-dependent cross-section
upper limits are in the range 2–4 fb (at 95 % CL) for masses
between 14 and 309 GeV/c2.
