      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].},
