Description
A search for narrow resonances decaying into dijet final states is
performed on data from proton-proton collisions at a center-of-mass
energy of 8 TeV, corresponding to an integrated luminosity of 18.8
fb-1 . The data were collected with the CMS detector using a
novel technique called data scouting, in which the information
associated with these selected events is much reduced, permitting
collection of larger data samples. This technique enables CMS to record
events containing jets at a rate of 1 kHz, by collecting the data from
the high-level-trigger system. In this way, the sensitivity to low-mass
resonances is increased significantly, allowing previously inaccessible
couplings of new resonances to quarks and gluons to be probed. The
resulting dijet mass distribution yields no evidence of narrow
resonances. Upper limits are presented on the resonance cross sections
as a function of mass, and compared with a variety of models predicting
narrow resonances. The limits are translated into upper limits on the
coupling of a leptophobic resonance ZB' to quarks,
improving on the results obtained by previous experiments for the mass
range from 500 to 800 GeV.
