      abstract     = {A search is presented for heavy vectorlike quarks (VLQs)
                      that couple only to light quarks in proton-proton collisions
                      at $\sqrt s$ =8 TeV at the LHC. The data were collected by
                      the CMS experiment during 2012 and correspond to an
                      integrated luminosity of 19.7 fb$^{−1}$. Both single and
                      pair production of VLQs are considered. The
                      single-production search is performed for down-type VLQs
                      (electric charge of magnitude 1/3), while the
                      pair-production search is sensitive to up-type (charge of
                      magnitude 2/3) and down-type VLQs. Final states with at
                      least one muon or one electron are considered. No
                      significant excess over standard model expectations is
                      observed, and lower limits on the mass of VLQs are derived.
                      The lower limits range from 400 to 1800 GeV, depending on
                      the single-production cross section and the VLQ branching
                      fractions $\mathfrak{B}$ to W, Z, and Higgs bosons. When
                      considering pair production alone, VLQs with masses below
                      845 GeV are excluded for $\mathfrak{B}$(W)=1.0, and below
                      685 GeV for $\mathfrak{B}$(W)=0.5,
                      B(Z)=$\mathfrak{B}$(H)=0.25. The results are more stringent
                      than those previously obtained for single and pair
                      production of VLQs coupled to light quarks.},
