In this talk, I will review the more important recent theoretical results in the computations and simulations of Higgs-production at the LHC.
Recent measurements from the ATLAS and CMS collaborations on Higgs boson fiducial and differential cross sections will be presented. The interpretation of results will also be shown in EFT frameworks wherever possible.
With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson properties can be performed using its decays into bosons and fermions. At the same time, the search for double-Higgs production can profit for the large integrated luminosity to provide more and more stringent limits. This talk presents measurements of Higgs boson properties using decays...
One of the puzzles of the SM is the large hierarchy between the Yukawa couplings of different flavours. Yukawa couplings of the first and the second generation are constrained only very weakly so far. However, one can obtain large deviations in the Yukawa couplings in several New Physics (NP) models, such as e.g new vector-like quarks, or new Higgs bosons that couple naturally to individual...
We present a global interpretation of Higgs, diboson, and top quark production and decay measurements from the LHC in the framework of the Standard Model Effective Field Theory (SMEFT) at dimension six. We constrain simultaneously 36 independent directions in its parameter space, and compare the outcome of the global analysis with that from individual and two-parameter fits. Our results are...
Exotic and rare decays of the Higgs boson provide a unique window for the discovery of new physics, as the Higgs boson may couple to hidden-sector states that do not interact under the Standard Model gauge transformations. Models predicting exotic Higgs boson decays to pseudoscalars can explain the galactic centre gamma-ray excess, if the additional pseudoscalar acts as the dark matter...
Higgs-pair production is one of the targets of the high-luminosity LHC and of future hadron colliders, as it allows for a direct probe of the trilinear Higgs coupling and hence of the mechanism behind electroweak symmetry breaking. This talk will present the impact of the full next-to-leading order QCD corrections to Higgs-pair production via gluon fusion, the main production mechanism at...
Double Higgs production at the LHC
Higgs factories based on e+e- colliders have the potential to measure the complete profile of the Higgs boson at a level of precision that goes qualitatively beyond the expected capabilities of the LHC. This talk will review the program of Higgs boson coupling measurements expected from the International Linear Collider, including the most recent updates. These measurements span the range of...
LEP precision on electroweak measurements was sufficient not to hamper the extraction of Higgs couplings at the LHC. But the foreseen permille-level Higgs measurements at future lepton colliders might suffer from parametric electroweak uncertainties in the absence of a dedicated electroweak program. We perform a joint, complete and consistent effective-field-theory analysis of Higgs and...
Single boson production overview (W, Z, ४) at the LHC
The abundant amount of data to be collected by the ATLAS and CMS collaborations in future runs of the Large Hadron Collider at CERN opens up a new era of precision physics. Some of the most prominent precision observables are related to processes with one or more jets in the final state. In order to fully exploit the potential of the LHC and the HL-LHC, it is imperative to make theoretical...
V+jets/+heavy flavour production at the LHC
Jet substructure and fragmentation (including TOP) at the LHC
Modelling the data at the LHC: status and issues (overview including soft QCD and TOP)
Status of VBS measurements at the LHC
We present a calculation of the NLO corrections to the gluon-induced
electroweak gauge boson pair production, gg->ZZ and gg->W+W-, matched to the PYTHIA 8 parton shower in the POWHEG approach. The calculation consistently incorporates the continuum background, the Higgs-mediated process, and their interference. We consider leptonic decay modes of the vector bosons and retain offshell and...
In this talk I will present a new NNLO calculation for the photon pair production process at the LHC where the 0-jettiness resolution variable is resummed to NNLL' accuracy.This higher-order resummation is based on a factorisation formula derived within Soft-Collinear Effective in the small 0-jettiness region.
Then I will discuss the implementation of this process within the Geneva Monte...
Multibosons production at the LHC (diboson, triboson)
Overview of precision measurements (angular coefficients, charge asymmetry, sin2Ө, mW, etc) at the LHC
Top quark Cross sections overview (including re-interpretation) at the LHC
Status of single top measurements at the LHC
Top quark mass measurements at the LHC
The remarkably large integrated luminosity collected by the ATLAS and CMS detectors during Run2 in proton–proton collisions at a center-of-mass of 13 TeV allows to use the large sample of top quark events to explore a variety of properties of top quark production and decay and to probe the presence on new physics that might break well established symmetries or manifest itself in rare...
Latest measurements of top quark pair production in association with EWK bosons (W, Z or ɣ) and heavy flavoured jets (cc,bb) using data collected by the ATLAS detector in LHCpp collisions at 13 TeV are presented. Inclusive and differential measurements are included. In addition, the most recent results of the very rare four-top-quark production are reported. Where available with full Run-2...
