Constraining the Higgs boson self-coupling via single-Higgs production measurement / Rossi, Eleonora (Universita e INFN, Roma Tre) /ATLAS Collaboration
After the discovery of the Higgs boson, one of the main targets of particle physics is the measurement of the Higgs boson couplings to fermions and vector bosons. Moreover, also of great interest is the observation of the interaction of the Higgs boson with itself, known as the Higgs boson self-coupling. [...]

Combined measurements of Higgs boson production and decays with the ATLAS detector / Zhou, Chen (Department of Physics, University of Wisconsin) /ATLAS Collaboration
The most precise measurements of Higgs boson cross sections, using the framework of simplified template cross sections, are obtained from a combination of measurements performed in the different Higgs boson decay channels. This talk presents the combined measurements, as well as their interpretations in terms of Higgs coupling modifiers and their ratios, also taking into account results of searches for H->invisible decays as well as off-shell Higgs boson production.

Measurements of ttbar pairs produced in association with electroweak gauge bosons using the ATLAS detector / Lopez Solis, Alvaro (University of Sheffield) /ATLAS Collaboration
The large centre-of-mass energy available at the proton-proton collider LHC allows for the copious production of top-quark-antiquark pairs in association with electroweak gauge bosons (W / Z / gamma) at high transverse momenta. The tt ̄Z and tt ̄W production cross sections are simultaneously measured using a combined fit in several analysis regions. [...]

Measurements of multiparton interactions at ATLAS / Martin, Tim (University of Warwick, Coventry) /ATLAS Collaboration
Measurements of multiple parton scattering in proton-proton collisions provide insight into the structure and long-range low-momentum scale interactions of the proton. In this talk we present two recent measurements using proton-proton collision data collected by the ATLAS experiment. [...]

Measurement of photon production at ATLAS / Cantero, Josu (Oklahoma State University) /ATLAS Collaboration
The production of prompt isolated photons at hadron colliders provides stringent tests of perturbative QCD and can be used to evaluate probability density functions of partons in the proton. In this talk, we present the measurements of the isolated-photon plus two jets and the inclusive isolated-photons cross sections, both measured using proton-proton collision data collected by the ATLAS experiment at Ãs=13 TeV.

Measurement of jet fragmentation using the ATLAS detector / Villaplana Perez, Miguel (INFN Milano and Universita' di Milano, Dipartimento di Fisica) /ATLAS Collaboration
Gluon splitting to b-quark pairs is a unique probe of the properties of gluon fragmentation, as the identified b-tagged jets provide a proxy for the quark daughters of the initial gluon. We present a measurement of key differential distributions related to $g \to b \bar{b}$ using data collected with the ATLAS detector at 13 TeV. [...]

Measurement of jet substructure observables using the ATLAS detector / Villaplana Perez, Miguel (INFN Milano and Universita' di Milano, Dipartimento di Fisica) /ATLAS Collaboration
Theoretical calculations for jet substructure observables with accuracy beyond leading-logarithm have recently become available. Such observables are significant not only for probing a new regime of QCD at a hadron collider, but also for improving the understanding of jet substructure properties that are used in many searches for physics beyond the Standard Model.

Precision electroweak measurements with ATLAS / Andari, Nansi (IRFU, CEA, Université Paris-Saclay) /ATLAS Collaboration
The electroweak sector of the Standard Model can be tested via precision measurements of fundamental observables: the effective leptonic weak mixing angle and the W-boson mass. The ATLAS collaboration has recently measured the W-boson mass using data collected during Run 1 at a centre-of-mass energy of 7 TeV: mW= 80370+/-19 MeV and the effective leptonic weak mixing angle using data collected at 8 TeV: sin2theta_eff^l = 0.23140 +- 0.00036.

Search for Higgs boson decays to beyond-the-Standard-Model light bosons in four-lepton events with the ATLAS detector at $\sqrt{s}=13$ TeV / Chiu, Yu Him Justin (University of Victoria) /ATLAS Collaboration
Current measurements permit the branching ratio of the SM Higgs to BSM particles to be as high as approximately 30%. Such exotic decays of the Higgs are well-motivated theoretically. [...]
