The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to b-quark pairs is a unique probe into the properties of gluon fragmentation because ...

A search is reported for Higgs boson decay to μ⁺μ⁻ using data with an integrated luminosity of 24.8 fb⁻¹ collected with the ATLAS detector in pp collisions at √s̅ = 7 and 8 TeV at the CERN Large Hadron Collider. The observed ...

A search for heavy resonances decaying to a W or Z boson and a Higgs boson in the qq̅(′)bb̅ final state is described. The search uses 36.1 fb⁻¹ of proton-proton collision data at √s = 13 TeV collected by the ATLAS detector ...

The ATLAS experiment at the LHC has measured the Higgs boson couplings and mass, and searched for invisible Higgs boson decays, using multiple production and decay channels with up to 4.7 fb⁻¹ of pp collision data at √s̅ ...

We search for the decay ϒ(1s) → γA⁰, A⁰ → gg or ss̅, where A⁰ is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric Standard Model. We use a sample of (17.6 ± 0.3) x10⁶ ϒ(1s) mesons produced ...

A direct search for lepton-flavour-violating H -> mu tau decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H -> mu tau(had) channel, where ...

A search for Higgs boson pair production pp → hh is performed with 19.5 fb⁻¹ of proton-proton collision data at √s̅ = 8 TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products ...

A search is presented for the decay ϒ(1S)→γA⁰, A⁰→cc̅, where A⁰ is a candidate for the CP-odd Higgs boson of the next-to-minimal supersymmetric standard model. The search is based on data collected with the BABAR detector ...

An improved measurement of the mass of the Higgs boson is derived from a combined fit to the reconstructed invariant mass spectra of the decay channels H → γγ and H → ZZ∗ → 4ℓ. The analysis uses the pp collision data sample ...

We report a search for Higgs bosons that are produced via vector boson fusion and subsequently decay into invisible particles. The experimental signature is an energetic jet pair with invariant mass of O(1)TeV and O(100)GeV ...
