Estimate of the $m_H$ shift due to interference between signal and background processes in the $H \rightarrow \gamma\gamma$ channel, for the $\sqrt{s} = 8$ TeV dataset recorded by ATLAS / Becot, Cyril (Department of Physics, New York University) ; Fayard, Louis (LAL, Univ. Paris-Sud, IN2P3/CNRS, Universite Paris-Saclay)
In the context of precision measurements of the properties of the Higgs boson, one of the most fundamental parameters is the knowledge of its mass. [...]

Measurement of track reconstruction inefficiencies in the core of jets via pixel dE/dx with the ATLAS experiment using $\sqrt{s}=13$ TeV $\textit{pp}$ collision data / Duffield, Emily Marie (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Facini, Gabriel (University of Chicago, Enrico Fermi Institute) ; Gadatsch, Stefan (European Laboratory for Particle Physics, CERN) ; Jansky, Roland (Institut fuer Astro- und Teilchenphysik der Leopold-Franzens-Universitaet Innsbruck) ; Morley, Anthony Keith (School of Physics, University of Sydney) ; Shapiro, Marjorie (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Pagan Griso, Simone (Lawrence Berkeley National Laboratory and University of California, Berkeley)
The inefficiency of the ATLAS charged particle reconstruction in the core of jets is studied as a function of the transverse momentum of the jet between 200 GeV and 1600 GeV, using proton-proton data collected by the ATLAS experiment from the LHC in 2015 at a center-of-mass energy of $\sqrt{s}=13$ TeV.

Study of higher-order QCD corrections in the $gg\rightarrow H\rightarrow VV$ process / Calandri, Alessandro (Centre de Physique des Particules de Marseille (CPPM), IN2P3-CNRS) ; Cerutti, Fabio (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Mansoulie, Bruno (Commissariat a l'Energie Atomique (CEA), DSM/IRFU, Centre d'Etudes de Saclay)
Several studies have shown that the high-mass off-peak regions in the $H\rightarrow ZZ$ and $H\rightarrow WW$ channels above the $VV$ mass threshold ($V=W,Z$) have sensitivity to off-shell Higgs production and interference effects. [...]
