| Summary: | A first search for pair production of dark matter candidates through vector boson fusion in proton-proton
collisions at ffiffi
s p ¼ 8 TeV is performed with the CMS detector. The vector boson fusion topology enhances
missing transverse momentum, providing a way to probe supersymmetry, even in the case of a compressed
mass spectrum. The data sample corresponds to an integrated luminosity of 18.5 fb−1, recorded by the
CMS experiment. The observed dijet mass spectrum is consistent with the standard model expectation. In
an effective field theory, dark matter masses are explored as a function of contact interaction strength. The
most stringent limit on bottom squark production with mass below 315 GeV is also reported, assuming a
5 GeV mass difference with respect to the lightest neutralino. |
