Higgs Boson Pair Production in Gluon Fusion at Next-to-Leading Order with Full Top-Quark Mass Dependence. [PDF]
Physical Review Letters, 2016 We present the calculation of the cross section and invariant mass distribution for Higgs boson pair production in gluon fusion at next-to-leading order (NLO) in QCD. Top-quark masses are fully taken into account throughout the calculation.

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Search for top-squark pair production in final states with one lepton, jets, and missing transverse momentum using 36 fb−1 of s√=13 TeV pp collision data with the ATLAS detector [PDF]
, 2017 The results of a search for the direct pair production of top squarks, the supersymmetric partner of the top quark, in final states with one isolated electron or muon, several energetic jets, and missing transverse momentum are reported.

EPJ Web of Conferences, 2019 The most recent results of a Higgs boson production and properties from the CMS Collaboration using the LHC Run 1 and Run 2 data are reported. These include analyses of a Higgs boson decaying to a pair of photons, four leptons via Z boson pair decays and

The Pair Production of Quarks [PDF]
Physikalische Blätter, 1997 AbstractA brief overview of the history of e+e− annihilation is presented, from the first days in the 1950s up to the start of PETRA in 1978. The pre‐LEP situation on R measurements is reviewed, followed by a description of how the b‐quark measurements at PETRA showed that the t‐quark must exist.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Differential top-quark pair production measurements
EPJ Web of Conferences, 2014 The large number of top quarks produced at the CERN Large Hadron Collider makes it possible to measure the top-quark pair production cross-section differentially with respect to different observables. Differential measurements are important for precision

Modulation effect in multiphoton pair production
Physics Letters B, 2017 We investigate the electron–positron pair production process in an oscillating field with modulated amplitude in the quantum kinetic formalism. By comparing the number density in the oscillating field with and without modulation, we find that the pair ...
