Title:          Sensitivity studies of different observables to new physics 
                in electroweak quartic gauge couplings at future lepton collider analyses

DESY group:     Theory

Type:           Tandem project: Online (Remote) part

Duration:       19th july - 10th sep 2021 (also 8th august - 10th sep 2021 possible)

Description:

Effective Field Theories (EFT) play a crucial role in systematic
approach to scrutinize new physics (NP) beyond the Standard Model
(SM). The Standard Model Effective Theory (SMEFT) allows us to model
deviations to the quartic gauge couplings within the Standard Model at
dimension-eight as genuine anomalous quartic gauge coupling (aQGC).
We aim to assess the sensitivity of different observables to new
physics in electroweak quartic gauge couplings at future lepton
colliders, and explore options to improve cut and selection
prescriptions for future lepton collider analyses. During the project,
we will utilize MadMiner, which provides a Python-based machine
learning framework for inference in particle physics, to infer the
full parameter dependence on the event outcome and perform the
respective statistical analysis. Especially, we aim to extend MadMiner
to use events generated by the Monte Carlo event generator WHIZARD,
which is well-suited for lepton collider simulations. Finally, we want
to infer the full distribution of the sensitivity to the
EFT-parameters over the complete phase space for different observables
from Monte Carlo samplings. With those results, we can then analyze
the unitarity-violating aspects of the higher-dimensional operators of
SMEFT on the different observables.

Special Qualifications expected:

Python and Shell scripting; basic knowledge about programming
(i.e. with Fortran) and machine-learning

Cancellation policy: In case the on-site part is cancelled due to COVID pandemic restriction
this online (remote) part of the project will still take place.
