Abstract
A search is presented for long-lived particles produced in pairs in proton-proton collisions at the LHC operating at a center-of-mass energy of
13
TeV
. The data were collected with the CMS detector during the period from 2015 through 2018, and correspond to a total integrated luminosity of
140
fb
−
1
. This search targets pairs of long-lived particles with mean proper decay lengths between 0.1 and
100
mm
, each of which decays into at least two quarks that hadronize to jets, resulting in a final state with two displaced vertices. No significant excess of events with two displaced vertices is observed. In the context of
R
-parity violating supersymmetry models, the pair production of long-lived neutralinos, gluinos, and top squarks is excluded at 95% confidence level for cross sections larger than 0.08 fb, masses between 800 and 3000 GeV, and mean proper decay lengths between 1 and 25 mm.
