Searches for new physics with top quarks in ATLAS and CMS / Iemmi, Fabio (Beijing, Inst. High Energy Phys.) /ATLAS and CMS Collaborations
The latest results by the ATLAS and CMS Collaborations on searches for new physics phenomena involving the production of top quarks are summarized. Both direct searches for new particles and interpretations of Standard Model measurements in terms of the presence of new physics are reported..

Observation of a $B_c^{*+}$ meson with the ATLAS detector
The first observation of a new meson state decaying into $B_c^+$ and a photon is presented using a dataset of $pp$ collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb$^{-1}$ [...]
