Boosted objects : a probe of beyond the standard model physics
- 2011

In: European Physical Journal C. - : Springer Science and Business Media LLC. - 1434-6044 .- 1434-6052. ; 71:6, s. 1661-
-
Journal article (peer-reviewed)abstract
- We present the report of the hadronic working group of the BOOST2010 workshop held at the University of Oxford in June 2010. The first part contains a review of the potential of hadronic decays of highly boosted particles as an aid for discovery at the LHC and a discussion of the status of tools developed to meet the challenge of reconstructing and isolating these topologies. In the second part, we present new results comparing the performance of jet grooming techniques and top tagging algorithms on a common set of benchmark channels. We also study the sensitivity of jet substructure observables to the uncertainties in Monte Carlo predictions.

Les Houches 2013: Physics at TeV Colliders: Standard Model Working Group Report
- 2014
-
Conference paper (peer-reviewed)abstract
- This Report summarizes the proceedings of the 2013 Les Houches workshop on Physics at TeV Colliders. Session 1 dealt primarily with (1) the techniques for calculating standard model multi-leg NLO and NNLO QCD and NLO EW cross sections and (2) the comparison of those cross sections with LHC data from Run 1, and projections for future measurements in Run 2.

A live video observatory reveals temporal processes at a shelf-depth whale-fall
- 2010
-
In: Cahiers De Biologie Marine. - 0007-9723. ; 51:4, s. 375-381
-
Journal article (peer-reviewed)abstract
- There have been very few studies of temporal processes at chemosynthetic ecosystems, even at relatively more accessible shallow water sites. Here we report the development and deployment of a simple cabled video observatory at 30 m water depth in Gullmarsfjorden, Sweden. The camera provides a live video feed to the internet of faunal activity in the experiments, which to date have included 5 separate whale-fall deployments. Our data suggest that the time to decomposition of small cetacean carcasses at shelf-depth settings is considerably slower than at deep-sea sites. We have also provided a new methodology for the deployment of low-cost live video observatories at up to 30 m water depth, which can be used both for research and outreach activities.

Bone-eating worms from the Antarctic: the contrasting fate of whale and wood remains on the Southern Ocean seafloor
- 2013
-
In: Proceedings of the Royal Society B-Biological Sciences. - : The Royal Society. - 0962-8452 .- 1471-2954. ; 280:1768
-
Journal article (peer-reviewed)abstract
- We report the results from the first experimental study of the fate of whale and wood remains on the Antarctic seafloor. Using a baited free-vehicle lander design, we show that whale-falls in the Antarctic are heavily infested by at least two new species of bone-eating worm, Osedax antarcticus sp. nov. and Osedax deceptionensis sp. nov. In stark contrast, wood remains are remarkably well preserved with the absence of typical wood-eating fauna such as the xylophagainid bivalves. The combined whale-fall and wood-fall experiment provides support to the hypothesis that the Antarctic circumpolar current is a barrier to the larvae of deep-water species that are broadly distributed in other ocean basins. Since humans first started exploring the Antarctic, wood has been deposited on the seafloor in the form of shipwrecks and waste; our data suggest that this anthropogenic wood may be exceptionally well preserved. Alongside the new species descriptions, we conducted a comprehensive phylogenetic analyses of Osedax, suggesting the clade is most closely related to the frenulate tubeworms, not the vestimentiferans as previous reported.
