Measurement of [formula] in Associated Production with the CMS Detector
The differential cross section of [formula] is measured with the CMS Detector. The Simplified Template Cross Section framework is used. The inclusive strength of the measured signal relative to the Standard Model is [formula], which agrees with the Standard Model within 2.1 standard deviations. The …

Hydrogen peroxide mediated oxidation of ferrous iron and associated production of hydroxyl radicals in natural aquatic systems
… when Fe(II) is complexed by NOM, with the HO production data able to be modelled using the same kinetic model developed to describe the Fe(II) oxidation process if it is assumed that only Fe(II)-NOM complexes yield HO . Overall, under circumneutral conditions Fe(II)-NOM complexes, although …

Studies of b-associated production and muonic decays of neutral Higgs bosons at the ATLAS experiment within the Minimal Supersymmetric Standard Model
This thesis presents a Monte Carlo study of neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) decaying into muons at the Atlas experiment at the CERN Large Hadron Collider. Signal and background processes are simulated using novel Monte Carlo generators that incorporate parts …

Direct search for exotic spin zero particles in the di-lepton final state of Higgs-Z associated production in sqrt(s) = 13 TeV pp collisions
… The channel considered here uses Higgs-Z---associated production with two leptons in the final state. The analysis uses a likelihood-fit profile of a multivariate discriminant to place 95% confidence limit upper bounds on the cross section of the proposed signal. A study of the performance …
