Search for dark matter and supersymmetry with a compressed mass spectrum in the vector boson fusion topology in proton-proton collisions at sqrt(s) = 8 TeV

Understand

A first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at sqrt(s) = 8 TeV is performed with the CMS detector.

• The vector boson fusion topology enhances missing transverse momentum, providing a way to probe supersymmetry also in the case of a compressed mass spectrum.
• The data sample corresponds to an integrated luminosity of 18.5 inverse femtobarns recorded by the CMS experiment.
• The observed dijet mass spectrum is consistent with the standard model expectation.
