Modification of jet shapes in PbPb collisions at √sNN=2.76TeV
(2014-03-07)
The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding ...
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 ...
Measurement of the tt¯ production cross section in the all-jets final state in pp collisions at √s = 8 TeV
(2016-03-08)
The cross section for tt¯ production in the all-jets final state is measured in pp collisions at a centre-of-mass energy of 8 TeV at the LHC with the CMS detector, in data corresponding to an integrated luminosity of 18.4 ...
Searches for supersymmetry based on events with b jets and four W bosons in pp collisions at 8 TeV
(2015-05-28)
Five mutually exclusive searches for supersymmetry are presented based on events in which b jets and
four W bosons are produced in proton–proton collisions at √s = 8 TeV. The data, corresponding to an
integrated luminosity ...
