I will discuss nonfactorizable QCD corrections from central jet veto to Higgs boson production at the Large Hadron Collider. At hadron colliders, phase factors in the scattering amplitudes lead to double-logarithmic corrections starting at four-loop order. I will introduce our recent work on the first all-order structure of these “super-leading” logarithms. Our analysis shows that in certain ... More

A combination of measurements of Higgs boson production cross sections and branching fractions is presented. The combination is based on the analyses of the Higgs boson decay modes H->yy, ZZ*, WW*, tautau, bb, mumu, and searches for decays into invisible final states. Up to 139 fb-1 of pp collision data collected at sqrt(s)=13 TeV with the ATLAS detector are used. Combined cross section measuremen ... More

Since the discovery of a scalar particle with mass at 125 GeV in the experiments ATLAS and CMS at LHC, different measurements based on its properties have been performed and the observations nicely correspond to the Higgs boson predicted by the Standard Model of particle physics. Among these measurements, the fiducial and differential cross-section play an important role in the test of the SM pred ... More

The most recent results for the cross-section measurements of the Higgs boson decaying into tau leptons at the ATLAS experiment will be presented. These results are setting the base for other searches in the Higgs boson sector in the tau final state aiming to look for physics beyond the Standard Model. The analysis is performed using the 139 ifb dataset recorded by the ATLAS experiment at LHC in t ... More

Testing the couplings of the Higgs boson to quarks is important to understand the origin of quark masses. The next most promising candidate is the decay to a pair of charm quark and antiquark. The presentation will focus on the analysis of the associated production of the Higgs boson with a W or Z boson performed by the ATLAS Collaboration using data collected between 2015 and 2018, and will de ...

Recently, we present for the first time a calculation of the complete next-to-leading order corrections to the $gg \to ZH$ process. We use the method of small mass expansion to tackle the most challenging two-loop virtual amplitude, in which the top quark mass dependence is retained throughout the calculations. We show that our method provides reliable numeric results in all kinematic regions, and ... More

The top quark is the heaviest elementary particle, studying its interaction with the Higgs boson not only helps to further understand the newly discovered Higgs boson itself, but also opens new opportunities to probe the BSM physics. This talk will summarize recent new experimental results that connect the top-Higgs interaction with searches of new physics beyond the standard model with the LHC Ru ... More

The electroweak symmetry breaking (EWSB) mechanism is still an undecided question in particle physics. We propose to utilize the single top quark and Higgs associated production ($th$), $Zh$ production via gluon fusion at the LHC to probe the couplings between the Higgs and the gauge bosons and further to test the EWSB. We demonstrate that the $th$ and $gg\to Zh$ productions are sensitive to the ... More
