Handbook to support the SCOR Best Practice Guide for ‘Multiple Drivers’ Marine Research
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Marine species and ecosystems are exposed to a wide range of environmental change – both detrimental (threats) and beneficial – due to human activities. Some of the changes are global, whereas others are regional or local. It is important to distinguish the scale of each threat as the solutions will differ. For example, the mitigation of a global problem requires a global response, which is more difficult to achieve than addressing a local problem with a local response. These wide-ranging changes are often referred to drivers or stressors.

On the Relation of the LHeC and the LHC
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The present note relies on the recently published conceptual design report of the LHeC and extends the first contribution to the European strategy debate in emphasising the role of the LHeC to complement and complete the high luminosity LHC programme. The brief discussion therefore focuses on the importance of high precision PDF and αs determinations for the physics beyond the Standard Model (GUTs, SUSY, Higgs). Emphasis is also given to the importance of high parton density phenomena in nuclei and their relevance to the heavy ion physics programme at the LHC.

Statistical combination of several important standard model Higgs boson search channels
- 2009
-
Rapport (refereegranskat)abstract
- In this note we describe statistical procedures for combination of results from independent searches for the Higgs boson. Here only the Standard Model Higgs is considered, although the methods can easily be extended to non-standard Higgs models as well as to other searches. The methods are applied to Monte Carlo studies of four important search channels: H to tau+ tau-, H to W+ W- to e-nu mu-nu, H to gamma gamma, and H to ZZ)(*) to 4 leptons. The statistical treatment relies on a large sample approximation that is expected to be valid for an integrated luminosity of at least 2 fb-1 . Results are presented for the expected statistical significance of discovery and expected exclusion limits.

Higgs boson searches in gluon fusion and vector boson fusion using the H $\to$ WW decay mode
- 2009
-
Rapport (refereegranskat)abstract
- The prospects for Higgs searches in the H + 0j (H to WW to e-nu mu-nu ), H + 2j (H to WW to e-nu mu-nu ), and H + 2 j (H to WW to l-nu qq) channels at ATLAS are presented, including realistic effects such as trigger efficiencies and detector misalignment, with an emphasis on practical methods to estimate the backgrounds using control samples in data. With 10 fb−1 of integrated luminosity, one would expect to be able to discover a Standard Model Higgs boson in the mass range 135 < mH < 190 GeV and to be able to measure its mass with a precision of about 7 GeV if its true mass is 130 GeV or about 2 GeV if its true mass is 160 GeV.
