(2013-01-10)
A search for supersymmetry in final states with jets and missing transverse energy is performed in pp collisions at a centre-of-mass energy of √s = 7 TeV. The data sample corresponds to an integrated luminosity of 4.98 ...
Measurement of the X(3872) production cross section via decays to J/ψπ+π− in pp collisions at √s = 7 TeV
(2013-04-29)
The production of the X(3872) is studied in pp collisions at √s = 7 TeV, using decays to J/ψπ+π−, where the J/ψ decays to two muons. The data were recorded by the CMS experiment and correspond to an integrated luminosity ...
