Abstract |
New particles with large masses that decay into hadronically interacting particles are predicted by many models of physics beyond the Standard Model. A search for a massive resonance that decays into pairs of dijet resonances is performed using 140 fb(-1) of proton-proton collisions at ffiffiffisp root s = 13 TeV recorded by the ATLAS detector during Run 2 of the Large Hadron Collider. Resonances are searched for in the invariant mass of the tetrajet system, and in the average invariant mass of the pair of dijet systems. A data-driven background estimate is obtained by fitting the tetrajet and dijet invariant mass distributions with a four-parameter dijet function and a search for local excesses from resonant production of dijet pairs is performed. No significant excess of events beyond the Standard Model expectation is observed, and upper limits are set on the production cross sections of new physics scenarios. |

Abstract |
We report on a measurement of the fraction of events with a W or Z boson which are produced diffractively in (p) over barp collisions at root s = 1.96 TeV, using data from 0.6 fb-1 of integrated luminosity collected with the CDF II detector equipped with a Roman- pot spectrometer that detects the (p) over bar from (p) over bar + p -> (p) over bar + [X + W/Z]. We find that (1.00 +/- 0.11)% of Ws and (0.88 +/- 0.22)% of Zs are produced diffractively in a region of antiproton or proton fractional momentum loss xi of 0.03 < xi < 0.10 and 4-momentum transferred squared t of -1 < t < 0 (GeV/c)(2), where we account for the events in which the proton scatters diffractively while the antiproton dissociates, (p) over bar + p -> [X + W/Z] + p, by doubling the measured proton dissociation fraction. We also report on searches for W and Z production in double Pomeron exchange, (p) over bar + p -> [X + W/Z] + p, and on exclusive Z production, (p) over bar + p -> (p) over bar + Z + p. No signal is seen above background for these processes, and comparisons are made with expectations. |

Abstract |
We study the processes gamma gamma -> K+K-eta and gamma gamma -> K+K-pi(0) using a data sample of 519 fb(-1) recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy e(+)e(-) collider at center-of-mass energies at and near the Upsilon(nS) (n = 2, 3, 4) resonances. We observe eta(c) -> K+K-pi(0) and eta(c) -> K+K-eta decays, measure their relative branching fraction, and perform a Dalitz plot analysis for each decay. We observe the K*(0)(1430) -> K eta decay and measure its branching fraction relative to the K pi decay mode to be R(K*(0)(1430)) = B(K*(0)(1430)-> K eta)/B(K*(0)(1430)-> K pi) = 0.092 +/- 0.025(- 0.025)(+0.010). The eta(c) -> K+K-eta and K*(0)(1430) -> K eta results correspond to the first observations of these channels. The data also show evidence for eta(c)(2S) -> K+K-pi(0) and first evidence for eta(c)(2S) -> K+K-eta. |

Abstract |
The charmless three- body decay modes B +/- -> K +/-pi(-)pi(-), B-+/- -> K-+/- (KK-)-K-+/-, B-+/- pi(-) K-K- and B-+/-pi(-)pi(-) are reconstructed using data, corresponding to an integrated luminosity of 3.0 fb(-1), collected by the LHCb detector. The inclusive CP asymmetries of these modes are measured to be [GRAPHICS] where the first uncertainty is statistical, the second systematic, and the third is due to the CP asymmetry of the B +/- J Psi K-+/- reference mode. The distributions of these asymmetries are also studied as functions of position in the Dalitz plot and suggest contributions from rescattering and resonance interference processes. |

Abstract |
A search for dark matter in association with a Higgs boson decaying to two photons is presented. This study is based on data collected with the ATLAS detector, corresponding to an integrated luminosity of 36.1 fb(-1) of proton-proton collisions at the LHC at a center-of-mass energy of 13 TeV in 2015 and 2016. No significant excess over the expected background is observed. Upper limits at 95% confidence level are set on the visible cross section for beyond the Standard Model physics processes, and the production cross section times branching fraction of the Standard Model Higgs boson decaying into two photons in association with missing transverse momentum in three different benchmark models. Limits at 95% confidence level are also set on the observed signal in two-dimensional mass planes. Additionally, the results are interpreted in terms of 90% confidence-level limits on the dark-matternucleon scattering cross section, as a function of the dark-matter particle mass, for a spin-independent scenario. |
