 Searches for Supersymmetry in ATLAS / Cervelli, Alberto (Universita e INFN, Bologna) After the discovery of the Higgs boson in ATLAS first run of data taking, and due to the lack of observation of new physics, searches for new particles such as Supersymmetric states are one of the main area of interest for the general purpose detectors operating at LHC [...] ATL-PHYS-PROC-2017-270. - 2017. - 9 p.

 Prospects for the measurement of the W-boson transverse momentum with a low pileup data sample at $\sqrt{s} = 13$ TeV with the ATLAS detector The imperfect knowledge of the $W$-boson transverse momentum ($p_T^W$) distribution is likely to be the limiting factor for future measurements of the $W$-boson mass at the Large Hadron Collider.

 Impact of Alternative Inputs and Grooming Methods on Large-R Jet Reconstruction in ATLAS During Run 1 of the LHC, the optimal reconstruction algorithm for large-$R$ jets in ATLAS, characterized in terms of the ability to discriminate signal from background and robust reconstruction in the presence of pileup, was found to be anti-$k_{t}$ jets with a radius parameter of 1.0, formed from locally calibrated topological calorimeter cell clusters and groomed with the trimming algorithm to remove contributions from pileup and underlying event.
