Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at root s=7 TeV
(American Physical Society, 2012-10-26)
A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of root s = 7 TeV. No ...
Tests of CMS hadron forward calorimeter upgrade readout box prototype
(IOP Publishing, 2012-10)
A readout box prototype for the CMS Hadron Forward calorimeter upgrade was built and tested in the CERN H2 beamline. The prototype was designed to enable simultaneous tests of different readout options for the four anode ...
Search for new physics with same-sign isolated dilepton events with jets and missing transverse energy
(American Physical Society, 2012-08-17)
A search for new physics is performed in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state. The analysis is based on a data sample corresponding to an integrated ...
Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-11)
A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a ...
Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV
(American Physical Society, 2012-10-01)
Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using ...
Search for pair production of first- and second-generation scalar leptoquarks in pp collisions at root s=7 TeV
(American Physical Society, 2012-09-01)
Results are presented from a search for the pair production of first- and second-generation scalar leptoquarks in proton-proton collisions at root s = 7 TeV. The data sample corresponds to an integrated luminosity of 5.0 ...
Search for third-generation leptoquarks and scalar bottom quarks in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-12)
Results are presented from a search for third-generation leptoquarks and scalar bottom quarks in a sample of proton-proton collisions at root s = 7TeV collected by the CMS experiment at the LHC, corresponding to an integrated ...
Search for stopped long-lived particles produced in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-08)
A search has been performed for long-lived particles that have stopped in the CMS detector, during 7TeV proton-proton operations of the CERN LHC. The existence of such particles could be inferred from observation of their ...
Study of the dijet mass spectrum in pp -> W + jets events at root s=7 TeV
(American Physical Society, 2012-12-21)
We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp -> W + 2-jet and W + 3-jet events to look for resonant enhancement. The data sample corresponds to an integrated ...
Search for new physics in events with same-sign dileptons and b-tagged jets in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-08)
A search for new physics is performed using isolated same-sign dileptons with at least two b-quark jets in the final state. Results are based on a 4.98 fb(-1) sample of proton-proton collisions at a centre-of-mass energy ...
