A search for stop production in R-parity-violating supersymmetry has been performed in ep interactions with the ZEUS detector at HERA, using an integrated luminosity of 65 pb. At HERA, the R-parity-violating coupling λ allows resonant squark production, ed → q̃. Since the lowest-mass squark state in most supersymmetry models is the light stop, t̃, this search concentrated on production of t̃, foll...

The ep collider HERA is ideally suited to search for new particles which could be produced resonantly via the fusion of the incoming 27.5 GeV electron and a quark from the incoming 920 GeV proton. Particle masses up to the electron-proton centre-of-mass energy, √ s = 318 GeV, are kine-matically accessible. Two collider experiments, H1 and ZEUS, have searched for the production of squarks, the s...
s p 1⁄4 7 and 8 TeV. No significant excess is found, and upper limits are set on the production rate of the claimed Xð5568Þ state within the LHCb acceptance. Upper limits are also set as a function of the mass and width of a possible exotic meson decaying to the Bsπ final state. The same limits also apply to a possible exotic meson decaying through the chain B 0 s π , B 0 s → Bsγ where the phot...

Search for resonant t ¯ t production in proton-proton collisions at ffiffi s p ¼ 8 TeV V. Khachatryan et al. A search is performed for the production of heavy resonances decaying into top-antitop quark pairs in proton-proton collisions at ffiffi ffi s p ¼ 8 TeV. Data used for t...
A measurement of the production processes of the recently discovered Higgs boson is performed in the two-photon final state using 4.5 fb−1 of proton-proton collisions data at ffiffi s p 1⁄4 7 TeV and 20.3 fb−1 at ffiffi s p 1⁄4 8 TeV collected by the ATLAS detector at the Large Hadron Collider. The number of observed Higgs boson decays to diphotons divided by the corresponding Standard Model pr...
