I was an editor for the internal documentation for both the 7 and 8 TeV analyses which both set world-leading limits at the time for stop pair production in the high stop mass region. Measurement of SM VH to bb production is essential to precisely measure Higgs coupling to fermions, a crucial remaining piece of the SM. This included searches for direct third generation SUSY particle pair production stop and sbottom in the jets and missing transverse momentum final state. I led the ATLAS all-hadronic stop analysis resulting in two publi- cations, one each from the and datasets.

Search for heavy resonances decaying to a W or Z boson and a Higgs boson in final states with leptons and b-jets in I also provided estimation of the QCD background for the stop analysis using a data driven method.

All in all, the thesis describes three different world-leading analyses in both Standard Model and SUSY physics and therefore represents a major contribution to the field.

Heavy flavour modelling Heavy flavour mcfaydwn modelling and the associated systematic uncertainties are important for many analyses. Lars Von Der Wense. Dispatched from the UK in 3 business days When will my order arrive? NLO merging schemes are the cutting edge technology for such samples and for Run 2 the implemen- tation of these schemes is essential to improve modelling and reduce systematic uncertainties.

In both analyses Mcfaydej introduced and optimised new kinematic variables for discrimination between signal and background that became essential for the sensitivity of the analysis. The stop squark analysis described, with substantial leading contributions from the author, is the first search for these particles at the LHC to use the jets plus missing transverse energy plus 0-lepton signature and provides the world’s best limits on the stop mass for light neutralino LSPs.

Third generation SUSY and t-t +Z production : Josh McFayden :

It is also responsible for the setting of common recipes tbesis theoretical systematic uncertainties. In the future, I am interested in developing searches that consider more challenging final states such as electroweak SUSY particle production and searches involving a Higgs boson in the SUSY particle decay chain, especially in the H to bb decay mode.

These were some of the most important mcafyden towards the end of Run 2 as naturalness arguments suggested that if SUSY exists lower mass stops and sbottoms should be accessible with the data available. My thesis was awarded a Springer thesis prize, the published Springer book can be found here. Dynamic Modeling of Complex Industrial Processes: I led the ATLAS all-hadronic stop analysis resulting in two publi- cations, one each from the and datasets.

All in all, the thesis describes three different world-leading analyses in both Standard Model and SUSY physics and therefore represents a major contribution to the mcafyden.

This is currently poorly constrained by data resulting in large systematic uncertainties.

Josh McFayden – Research

With this new NLO regime computation of increasingly complicated processes is required and is a significant bottleneck for experiments.

These searches are very strongly motivated by naturalness arguments. The group is responsible for the development and validation of MC generators and samples for analyses. I led the production of ttV MC samples including determination of generator level systematic uncertainties that are vital for a huge number of ATLAS analyses and was recently an editor of a public note documenting the current status of these samples in ATLAS.

Table of contents Introduction and Theoretical Background. Measurement of SM VH to bb production is essential to precisely measure Higgs coupling to fermions, a crucial remaining piece of the SM.

Better integration of such computations into High Performance Computing centres is vital and I have the knowledge and experience to facilitate such developments.

The thesis focuses on searches for stop and sbottom squarks, the SUSY partners of the top and bottom quarks, which are expected to be lighter than the partners of the first and second generation quarks and therefore good candidates for the first evidence of SUSY.
