Analysis of a combined measurement of $W^\pm\rightarrow\ell^\pm\nu\ (\ell=e,\mu)$ cross sections differential in $m_T^W$ and $m_T^W\otimes|\eta|$ at high transverse masses at $\sqrt{s}=13\ \mathrm{TeV}$ with the ATLAS detector

Physicists from different disciplines study various phenomena in nature. One such discipline is particle physics. It describes the most fundamental constituents of matter and their interactions. To provide a complete theory, the Standard Model of elementary particle physics has been developed. It is able to describe and predict most of the observed effects very accurately. Its most recent success was the discovery of the Higgs boson in 2012. However, there are also some phenomena that cannot be explained by the Standard Model. One of these phenomena is the nature of dark matter. Furthermore, the observation of neutrino oscillation contradicts the Standard Model [1, 2, 3]. Another very important aspect is that it does not include the gravitational force. Therefore, it is important to precisely test the predictions of the Standard Model to find deviations, which can lead to explanations for such undescribed effects.
