Описание: This thesis presents innovative contributions to the CMS experiment in the new trigger system for the restart of the LHC collisions in Run II, as well as original analysis methods and important results that led to official publications of the Collaboration.
The author's novel reconstruction algorithms, deployed on the Field-Programmable Gate Arrays of the new CMS trigger architecture, have brought a gain of over a factor 2 in efficiency for the identification of tau leptons, with a very significant impact on important H boson measurements, such as its decays to tau lepton pairs and the search for H boson pair production.
He also describes a novel analysis of HH ? bb tautau, a high priority physics topic in a difficult channel. The original strategy, optimisation of event categories, and the control of the background have made the result one of the most sensitive concerning the self-coupling of the Higgs boson among all possible channels at the LHC.
Описание: This book reports on a new result from the KL 0 search at the J-PARC KOTO experiment, which sets an upper limit of 3x10-9 for the branching fraction of the decay at the 90% confidence level, improving the previous best limit by an order of magnitude.
Описание: In this thesis the author has conducted a search for the Higgs boson in the H ГЇВїВЅ ZZ ГЇВїВЅ l +l - qq Decay Channel at CMS with 4.6 fbГЇВїВЅ 1 of data collected by the Compact Muon Experiment. The book goes on to present statistical tools for analysis, with their results.

Описание: This thesis describes the stand-alone discovery and measurement of the Higgs boson in its decays to two W bosons using the Run-I ATLAS dataset. these include new methods for evaluating uncertainties on the jet binning used in the analysis and for estimating the background due to associated production of a W boson and an off-shell photon.

Описание: One promising experimental approach involves the use of large volumes of isotope-loaded liquid scintillator, but new techniques for background identification and suppression must be developed in order to reach the required sensitivity levels and clearly distinguish the signal.

Описание: This thesis describes one of the first measurements at the CERN LHC -- the world`s largest and highest-energy particle collider. The CMS collision data is analyzed, and results in the first measurement of the inclusive b cross section using semileptonic decays at a center of mass energy of 7 TeV.
