The production of jets and prompt isolated photons at hadron colliders provides stringent tests of perturbative QCD and are sensitive to parton distribution functions in the proton. In this talk we discuss the most recent measurements done using proton-proton collision data collected by the ATLAS experiment at √s=13 TeV with full Run-2 dataset. For what concerns measurement with photons, a...

Measurements of multiple electroweak bosons production and vector boson scattering, as well as photon-photon fusion at the LHC are stringent tests of the electroweak sector and provide a model-independent means to search for new physics at the TeV scale. In this talk, we present the most recent results on multi-boson production in proton-proton collisions at √s=13 TeV performed by the ATLAS...

We present the progress towards calculation of necessary ingredients for the mixed QCD-EW corrections to Drell-Yan processes outside the resonance region, where new physics searches are potentially relevant.

Measurement of Top quark properties takes advantage of the cleanness of the dilepton channel of top quark pair production. However, it is challenging to reconstruct the full final state kinematically due to the missing transverse momentum arising from two neutrinos, and a two-fold ambiguity in assigning the correct b-jet lepton. I will provide an overview of several existing methods to resolve...

After the triumph of discovering the Higgs boson at the CERN Large Hadron Collider, people are getting increasingly interested in studying the Higgs properties in detail and searching for the physics beyond the Standard Model (SM). A multi-TeV lepton collider provides a clean experimental environment for both the Higgs precision measurements and the discovery of new particles. In high-energy...

With the standard model working well in describing the collider data, the focus is now

on determining the standard model parameters as well as for any hint of deviation. In particular, the
determination of the couplings of the Higgs boson with itself and with other particles of the model
is important to better understand the electroweak symmetry breaking sector of the model. In... -

We study the QCD Adler function in the energy region $\approx 0.7-2.5$ GeV, in which the non-perturbative effects become dominant. Our analysis is a renormalon-based evaluation using transseries within the resurgence of the Renormalization-Group-Equation and does not require the Operator-Product-Expansion.

The study of the associated production of vector bosons and jets constitutes an excellent environment to check numerous QCD predictions. Total and differential cross sections of vector bosons produced in association with jets has been studied at CMS. Differential distributions as function of a broad range of kinematical observables are measured and compared with theoretical predictions. These...
