Abstract
Searches are presented for direct production of
top or bottom squark pairs in proton–proton collisions at the
CERN LHC. Two searches, based on complementary tech-
niques, are performed in all-jet final states that are character-
ized by a significant imbalance in transverse momentum. An
additional search requires the presence of a charged lepton
isolated from other activity in the event. The data were col-
lected in 2015 at a centre-of-mass energy of 13 TeV with the
CMS detector and correspond to an integrated luminosity of
2.3 fb

. No statistically significant excess of events is found
beyond the expected contribution from standard model pro-
cesses. Exclusion limits are set in the context of simplified
models of top or bottom squark pair production. Models with
top and bottom squark masses up to 830 and 890 GeV, respec-
tively, are probed for light neutralinos. For models with top
squark masses of 675 GeV, neutralino masses up to 260 GeV
are excluded at 95% confidence level.
