Abstract A test of CP invariance in Higgs boson production via vector-boson fusion is performed in the H → τ τ decay channel. This test uses the Optimal Observable method and is carried out using 36.1 fb − 1 of s = 13 TeV proton–proton collision data collected by the ATLAS experiment at the LHC. Contributions from CP-violating interactions between the Higgs boson and electroweak gauge bosons are described by an effective field theory, in which the parameter d ˜ governs the strength of CP violati...

We report measurements of the flux-integrated \bar{\nu}_\muand \bar{\nu}_\mu+\nu_\mucharged-current cross-sections on water and hydrocarbon targets using the T2K anti-neutrino beam, with a mean neutrino energy of 0.86 GeV. The signal is defined as the (anti-)neutrino charged-current interaction with one induced \mu^\pmand no detected charged pion nor proton. These measurements are performed using a new WAGASCI module recently added to the T2K setup in combination with the INGRID Proton ...

Higgs boson properties are studied in the four-lepton decay channel (where lepton = e \mu using 139 fb^{-1}of proton-proton collision data recorded at \sqrt{s}= 13 TeV by the ATLAS experiment at the Large Hadron Collider. The inclusive cross-section times branching ratio for H\to ZZ^*decay is measured to be 1.34 \pm 0.12pb for a Higgs boson with absolute rapidity below 2.5, in good agreement with the Standard Model prediction of 1.33 \pm 0.08pb. Cross-sections times branchin...

The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many measurements of jet substructure at the LHC and previous colliders, but the targeted observables mix physical effects from various origins. Based on a recent proposal to factorize physical effects, this Letter presents a double-differential cross-section measurement of the Lund...

Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of the PMNS mixing matrix. T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events. Including information from the kinematic distribution of observed events, the hypothesis of no electron antineutrino appearance is disfavored with a significance of 2.40{\sigma} and no discrepanc...

Electroweak symmetry breaking explains the origin of the masses of elementary particles via their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering of massive vector bosons (with spin one) at the Large Hadron Collider allows to probe the nature of electroweak symmetry breaking with an unprecedented sensitivity. Among all processes related to vector-boson scattering, the electroweak production of two jets and a Zboson pair is...

A search for Higgs boson decays into a Zboson and a light resonance in two-lepton plus jet events is performed, using a ppcollision dataset with an integrated luminosity of 139 fb^{-1}collected at \sqrt{s}=13TeV by the ATLAS experiment at the CERN LHC. The resonance considered is a light boson with a mass below 4 GeV from a possible extended scalar sector, or a charmonium state. Multivariate discriminants are used for the event selection and for evaluating the mass of the light reson...

A search for long-lived particles decaying into hadrons and at least one muon is presented. The analysis selects events that pass a muon or missing-transverse-momentum trigger and contain a displaced muon track and a displaced vertex. The analyzed dataset of proton-proton collisions at \sqrt{s} = 13TeV was collected with the ATLAS detector and corresponds to 136 fb^{-1} The search employs dedicated reconstruction techniques that significantly increase the sensitivity to long-lived particle...

This paper reports the first simultaneous measurement of the double differential muon neutrino charged-current cross section on oxygen and carbon without pions in the final state as a function of the outgoing muon kinematics, made at the ND280 off-axis near detector of the T2K experiment. The ratio of the oxygen and carbon cross sections is also provided to help validate various models' ability to extrapolate between carbon and oxygen nuclear targets, as is required in T2K oscillation analyses. ...

Evidence for electroweak production of two jets in association with a Z\gammapair in \sqrt{s} = 13TeV proton-proton collisions at the Large Hadron Collider is presented. The analysis uses data collected by the ATLAS detector in 2015and 2016that corresponds to an integrated luminosity of 36.1~\mathrm{fb}^{-1} Events that contain a Zboson candidate decaying leptonically into either e^{+}e^{-}or \mu^{+}\mu^{-} a photon, and two jets are selected. The electroweak component is...
