Periodic Reporting for period 1 - SMEFTONE (The Standard Model Effective Field Theory at One Loop)
Reporting period: 2020-09-01 to 2022-08-31
This grant handled performing precision theoretical calculations for comparison with some of the most precise experiments in particle physics. In particular I applied a mathematical tool that allows us to infer information about potential new particles that cannot be produced directly at experiments, but whose properties can be inferred by how they change the behavior of the known measurable particles.
This is important firstly as it is a scientific endeavor pushing our understanding of nature, but also secondly in supporting society through training students whose analytic skills have applications across all of industry as well as because of the new methodologies we develop which may be adapted by industry in the future.
The overall objectives were to calculate precision theoretical predictions for the behavior of the Z boson particle and the recently discovered Higgs particle which can then be compared to experimental measurements. If the the experimental measurements deviate from the prediction of the Standard Model of particle physics, my calculations will tell us important information about the kinds of particles that could be causing this shift in behavior and how to look for them at future colliders.

Work performed:
1) I systematically improved our predictions of how particles move from one location to the other in a mathematical framework that allows us to infer the existence of new particles.
2) I systematically improved our predictions of how the Z boson particle is produced and decays in a mathematical framework that allows us to infer the existence of new particles.
3) I systematically improved our predictions of how the Higgs particle decays to two fermions (for example electrons) and a photon (the particle of light) in a mathematical framework that allows us to infer the existence of new particles.
This work was disseminated through 6 publications (one has been accepted for publication, but has not yet been published). I also attended four conferences/workshops where I gave talks and gave seminars at four different universities, some of these were virtual events due to the covid 19 situation.

This report marks the end of the project.
My work pushed calculations beyond the state of the art for the predictions of how a particle moves from one place to another, how the Z boson particle is produced and decays, and how the Higgs particle decays into two leptons and a photon in the context of a mathematical framework that allows us to infer the existence of new particles through measured deviations at experiments.
There is no economic impacts of this work. The social impact is that my work has pushed forward human understanding of how particles interact and with future precision measurements of the properties of the Z boson particle and Higgs particle we may be able to infer the existence of new particles that could change our understanding of the universe.
