Study of weak vacuum polarization in $Z \to 2l \gamma$
The goal of the work was to perform a search of weak vacuum polarization in the channel $Z \to 2l \gamma$ using $20 \text{ fb}^{-1}$ of $pp$ collision data collected by the ATLAS experiment in 2012 at 8 TeV. The ratio of the distribution of an invariant mass of $l\gamma$ obtained from experimental...
