JOSH MCFAYDEN THESIS

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. Search for heavy resonances decaying to a W or Z boson and a Higgs boson in final states with leptons and b-jets in With this new NLO regime computation of increasingly complicated processes is required and is a significant bottleneck for experiments.

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.

These were some of the most important searches 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. These searches are very strongly motivated by naturalness arguments. This will help to constrain the MC gesensitivity can be found with sufficient data. Better integration of such computations into High Performance Computing centres is vital and I have the knowledge and experience to facilitate such developments.

Better integration of such computations into High Performance Computing centres is vital and I have the knowledge and experience to facilitate such developments. I also provided estimation of the QCD background for the stop analysis using a data driven method.

Implementation and validation of these new MC generator configurations requires significant tech- nical expertise and a large amount of coordination with the MC generator authors. Table of contents Introduction and Theoretical Background.

I led the ATLAS all-hadronic stop analysis resulting in two publi- cations, one each from the and datasets. 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.

Heavy flavour modelling Heavy flavour production modelling and the associated systematic uncertainties are important for many analyses. These were some of the most important searches 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.

I am a member of the MCNet collaboration which is dedicated to developing and supporting general-purpose Monte Carlo event generators throughout the LHC era and beyond.

These searches are very strongly motivated by naturalness arguments. This included searches for direct third generation SUSY particle pair production stop and sbottom in the jets and missing transverse momentum final state.

Research Interests

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.

Other books in this series. Measurement of SM VH to bb production is essential to precisely measure Higgs coupling to fermions, a crucial remaining piece of the SM.

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.

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

This is currently poorly constrained by data resulting in large systematic uncertainties. I was an theiss 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. Dynamic Modeling of Complex Industrial Processes: Both processes are dominant backgrounds in many SUSY searches.

Lars Von Der Wense. This involved leading a team responsible for production of all ATLAS Monte Carlo simulation and managing the generation of billions of simulated collision events. It describes novel techniques for estimating and rejecting the Standard-Model backgrounds to searches for these particles.

I have also contributed significantly to development of MC generators, improving MC modelling and understanding of the corresponding uncertainties.

It is also responsible for the setting of common recipes for theoretical systematic uncertainties.
