The ATLAS experiment has performed measurements of B-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and CP violation in the neutral B meson systems.
This talk will focus on the latest results from the ATLAS collaboration, in particular for rare processes 𝐵0𝑠→𝜇𝜇 and 𝐵0→𝜇𝜇, and CP violation in the 𝐵0𝑠→𝐽/𝜓𝜙 decays. In the latter, the...
We present a combined analysis of low energy precision constraints and LHC searches for leptoquarks which couple to first generation fermions. Considering all ten leptoquark representations, five scalar and five vector ones, we study at the precision frontier the constraints from $K \rightarrow\pi\nu\nu$, $K\rightarrow \pi e^+e^-$, $K_0−\bar{K}_0$ and $D_0−\bar{D}_0$ mixing, as well as from...
