Searches for heavy Higgs bosons in two-Higgs-doublet models and for t - GT ch decay using multilepton and diphoton final states in pp collisions at 8 TeV
(Physical Review D, 2014)
Searches are presented for heavy scalar (H) and pseudoscalar (A) Higgs bosons posited in the two doublet model (2HDM) extensions of the standard model (SM). These searches are based on a data sample of pp collisions collected ...
Measurement of diffractive dissociation cross sections in pp collisions at root s=7 TeV
(Physical Review D, 2015)
Measurements of diffractive dissociation cross sections in pp collisions at root s = 7 TeV are presented in kinematic regions defined by the masses M-X and M-Y of the two final-state hadronic systems separated by the largest ...
Simultaneous measurements of the t(t)over-bar, W+W-, and Z/gamma* - GT tau tau production cross-sections in pp collisions at root s=7 TeV with the ATLAS detector
(Physical Review D, 2015)
Simultaneous measurements of the t (t) over bar, W+W-, and Z/gamma* - GT tau tau production cross-sections using an integrated luminosity of 4.6 fb(-1) of pp collisions at root s = 7 TeV collected by the ATLAS detector at ...
Search for vectorlike charge 2/3 T quarks in proton-proton collisions at root(s)=8 TeV
(Physical Review D, 2016)
A search for fermionic top quark partners T of charge 2/3 is presented. The search is carried out in proton-proton collisions corresponding to an integrated luminosity of 19.7 fb(-1) collected at a center-of-mass energy ...
Measurement of the top quark mass using charged particles in pp collisions at root s=8 TeV
(Physical Review D, 2016)
A novel technique for measuring the mass of the top quark that uses only the kinematic properties of its charged decay products is presented. Top quark pair events with final states with one or two charged leptons and ...
Limits on the Higgs boson lifetime and width from its decay to four charged leptons
(Physical Review D, 2015)
Constraints on the lifetime and width of the Higgs boson are obtained from H - GT ZZ - GT 4l events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb(-1) at a ...
Measurement of Higgs boson production in the diphoton decay channel in pp collisions at center-of-mass energies of 7 and 8 TeV with the ATLAS detector
(Physical Review D, 2014)
A measurement of the production processes of the recently discovered Higgs boson is performed in the two-photon final state using 4.5 fb(-1) of proton-proton collisions data at root s = 7 TeV and 20.3 fb(-1) at root s = 8 ...
Search for the standard model Higgs boson produced through vector boson fusion and decaying to b(b)over-bar
(Physical Review D, 2015)
A first search is reported for a standard model Higgs boson (H) that is produced through vector boson fusion and decays to a bottom-quark pair. Two data samples, corresponding to integrated luminosities of 19.8 fb(-1) and ...
Searches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV
(Physical Review D, 2014)
Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs). ...
Measurements of jet multiplicity and differential production cross sections of Z plus jets events in proton-proton collisions at root s=7 TeV
(Physical Review D, 2015)
Measurements of differential cross sections are presented for the production of a Z boson and at least one hadronic jet in proton-proton collisions at root s = 7 TeV, recorded by the CMS detector, using a data sample ...
