Descripción
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 √{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 β
=1.0 (0.5 ) , where β 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
β =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.
