A search for pair production of first and second generation leptoquarks is performed in final states containing either two charged leptons and two jets, or one charged lepton, one neutrino and two jets, using proton-proton collision data at root s = 8 TeV. The data, corresponding to an integrated luminosity of 19.7 fb(-1), were recorded with the CMS detector at the LHC. First-generation scalar leptoquarks with masses less than 1010 (850) GeV are excluded for beta = 1.0 (0.5), where beta is the branching fraction of a leptoquark decaying to a charged lepton and a quark. Similarly, second-generation scalar leptoquarks with masses less than 1080 (760) GeV are excluded for beta = 1.0 (0.5). Mass limits are also set for vector leptoquark production scenarios with anomalous vector couplings, and for R-parity violating supersymmetric scenarios of top squark pair production resulting in similar final-state signatures. These are the most stringent limits placed on the masses of vector leptoquarks and RPV top squarks to date. ; Austrian Federal Ministry of Science, Research and Economy; Austrian Science Fund; Belgian Fonds de la Recherche Scientifique; Brazilian Funding Agency (CNPq); Brazilian Funding Agency (CAPES); Brazilian Funding Agency (FAPERJ); Brazilian Funding Agency (FAPESP); Bulgarian Ministry of Education and Science; CERN; Chinese Academy of Sciences; Ministry of Science and Technology; National Natural Science Foundation of China; Colombian Funding Agency (COLCIENCIAS); Croatian Ministry of Science, Education and Sport; Croatian Science Foundation; Research Promotion Foundation, Cyprus; Ministry of Education and Research, Estonia; Estonian Research Council, Estonia [IUT23-4, IUT23-6]; European Regional Development Fund, Estonia; Academy of Finland, Finnish Ministry of Education and Culture; Helsinki Institute of Physics; Institut National de Physique Nucleaire et de Physique des Particules / CNRS, France; Commissariat a l'Energie Atomique et aux Energies Alternatives / CEA, France; Bundesministerium fur ...
