Observation of a cross-section enhancement near the $t\bar{t}$ production threshold in $\sqrt{s}=$13 TeV $pp$ collisions with the ATLAS detector

Speaker

Baptiste Ravina (CERN)

Description

I will present the recent ATLAS result on the observation of an excess near the $t\bar{t}$ threshold that is consistent with the formation of "toponium" quasi-bound states. Details of the experimental and statistical analysis techniques will be presented, with an emphasis on the modelling of both pQCD and pNRQCD $t\bar{t}$ production.
