abstract = {A search for pair production of third-generation scalar
leptoquarks and supersymmetric top quark partners, top
squarks, in final states involving tau leptons and bottom
quarks is presented. The search uses events from a data
sample of proton-proton collisions corresponding to an
integrated luminosity of 19.7 inverse femtobarns, collected
with the CMS detector at the LHC with sqrt(s) = 8 TeV. The
number of observed events is found to be in agreement with
the expected standard model background. Third-generation
scalar leptoquarks with masses below 740 GeV are excluded at
$95\%$ confidence level, assuming a $100\%$ branching
fraction for the leptoquark decay to a tau lepton and a
bottom quark. In addition, this mass limit applies directly
to top squarks decaying via an R-parity violating coupling
lambda'[333]. The search also considers a similar signature
from top squarks undergoing a chargino-mediated decay
involving the R-parity violating coupling lambda'[3jk]. Each
top squark decays to a tau lepton, a bottom quark, and two
light quarks. Top squarks in this model with masses below
580 GeV are excluded at $95\%$ confidence level. The
constraint on the leptoquark mass is the most stringent to
date, and this is the first search for top squarks decaying
via lambda'[3jk].},
