@misc{10481/76574, year = {2022}, month = {7}, url = {http://hdl.handle.net/10481/76574}, abstract = {This article presents the results of two studies of Higgs boson properties using the WW*(-> e nu mu nu)jj final state, based on a dataset corresponding to 36.1fb(-1) of root s = 13 TeV proton-proton collisions recorded by the ATLAS experiment at the Large Hadron Collider. The first study targets Higgs boson production via gluon-gluon fusion and constrains the CP properties of the effective Higgs-gluon interaction. Using angular distributions and the overall rate, a value of tan (alpha) = 0.0 +/- 0.4(stat.) +/- 0.3(syst.) is obtained for the tangent of the mixing angle for CP-even and CP-odd contributions. The second study exploits the vector-boson fusion production mechanism to probe the Higgs boson couplings to longitudinally and transversely polarised W and Z bosons in both the production and the decay of the Higgs boson; these couplings have not been directly constrained previously. The polarisation-dependent coupling-strength scale factors are defined as the ratios of the measured polarisation-dependent coupling strengths to those predicted by the Standard Model, and are determined using rate and kinematic information to be a(L) = 0.91(-0.18)(+0.10)(stat.)(-0.17)(+0.09)(syst.) and a(T) = 1.2 +/- 0.4(stat.)(-0.3)(+0.2)(syst.). These coupling strengths are translated into pseudo-observables, resulting in kappa(VV) = 0.91(-0.18)(+0.10)(stat.)(-0.17)(+0.09)(syst.) and epsilon(VV) = 0.13(-0.20)(+0.28)(stat.)(-0.10)(+0.08)(syst.). All results are consistent with the Standard Model predictions.}, organization = {ANPCyT, Argentina}, organization = {YerPhI, Armenia}, organization = {ARC, Australia}, organization = {BMWFWandFWF,Austria}, organization = {ANAS, Azerbaijan}, organization = {SSTC, Belarus}, organization = {CNPq and FAPESP, Brazil}, organization = {NSERC, NRC and CFI, Canada}, organization = {CERN}, organization = {ANID, Chile}, organization = {CAS, MOST and NSFC, China}, organization = {Minciencias, Colombia}, organization = {MEYS CR, Czech Republic}, organization = {DNRF and DNSRC, Denmark}, organization = {IN2P3- CNRS and CEA-DRF/IRFU, France}, organization = {SRNSFG, Georgia}, organization = {BMBF, HGF andMPG, Germany}, organization = {GSRI, Greece}, organization = {RGC and Hong Kong SAR, China}, organization = {ISF and Benoziyo Center, Israel}, organization = {INFN, Italy}, organization = {MEXT and JSPS, Japan}, organization = {CNRST, Morocco}, organization = {NWO, Netherlands}, organization = {RCN, Norway}, organization = {MEiN, Poland}, organization = {FCT, Portugal}, organization = {MNE/IFA, Romania}, organization = {JINR}, organization = {MES of Russia and NRC KI, Russian Federation}, organization = {MESTD, Serbia}, organization = {MSSR, Slovakia}, organization = {ARRS and MIZŠ, Slovenia}, organization = {DSI/NRF, South Africa}, organization = {MICINN, Spain}, organization = {SRC and Wallenberg Foundation, Sweden}, organization = {SERI, SNSF and Cantons of Bern and Geneva, Switzerland}, organization = {MOST, Taiwan}, organization = {TAEK, Turkey}, organization = {STFC, United Kingdom}, organization = {DOE and NSF, USA}, organization = {BCKDF, CANARIE, Compute Canada and CRC, Canada}, organization = {COST, ERC, ERDF, Horizon 2020 and Marie Skłodowska-Curie Actions, European Union}, organization = {Investissements d’Avenir Labex, Investissements d’Avenir Idex and ANR, France}, organization = {DFG and AvH Foundation, Germany}, organization = {Herakleitos, Thales and Aristeia programmes co-financed by EU-ESF and the Greek NSRF, Greece}, organization = {BSFNSF and GIF, Israel}, organization = {Norwegian 2014-2021, Norway}, organization = {NCNandNAWA, Poland}, organization = {La Caixa Banking Foundation, CERCA Programme Generalitat de Catalunya and PROMETEO and GenT Programmes Generalitat Valenciana, Spain}, organization = {Göran Gustafssons Stiftelse, Sweden}, organization = {The Royal Society and Leverhulme Trust, UK.}, publisher = {Springer}, title = {Constraints on Higgs boson properties using WW*(-> e nu mu nu)jj production in 36.1 fb(-1) of root s=13 TeV pp collisions with the ATLAS detector}, doi = {10.1140/epjc/s10052-022-10366-1}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
