The soft drop jet mass cross section is as an attractive candidate for precision measurements such as 𝛼𝑠 and top mass, as it can be perturbatively calculable to high accuracy besides being more robust against nonperturbative and underlying event corrections. In this talk I will focus our work on studying prospects of measurement of 𝛼𝑠 at the LHC using state of the art resummed cross section...
Measurements in boosted top quark production test the Standard Model in a previously unexplored regime with a strongly enhanced sensitivity to high-scale new phenomena. Dedicated techniques have been developed to reconstruct and identify boosted top quarks. In this contribution measurements of the ATLAS experiment are presented of the differential cross section and asymmetries in this extreme...
Using the tracking system at the LHC, one can efficiently suppress pile-up contamination and im- prove angular resolution. Observables that only depend on charged particles (tracks) are not in- frared safe in perturbation theory, so any calculation of track-based observables must account for hadronization effects. This can be done by matching the partonic cross section onto perturbative...
