 Measurements of the W production cross sections in association with jets with the ATLAS detector This paper presents cross sections for the production of a W boson in association with jets, measured in proton--proton collisions at $\sqrt{s}=7$ TeV with the ATLAS experiment at the Large Hadron Collider.

 The HL-LHC accelerator physics challenges / Fartoukh, S (CERN) ; Zimmermann, F (CERN) We review the conceptual baseline of the HL-LHC project, putting into perspective the main beam physics challenges of this new collider in comparison with the existing LHC, and the series of solutions and possible mitigation measures presently envisaged..

 Two-Field Analysis of No-Scale Supergravity Inflation / Ellis, John ; Garcia, Marcos A G ; Nanopoulos, Dimitri V ; Olive, Keith A Since the building-blocks of supersymmetric models include chiral superfields containing pairs of effective scalar fields, a two-field approach is particularly appropriate for models of inflation based on supergravity.

 Jet and Photon Physics / Peruzzi, Marco (Zurich, ETH) /ATLAS and CMS Collaborations Jet production in proton-proton collisions is one of the main phenomenological predictions of QCD. The ATLAS and CMS Collaborations have performed measurements of several jet observables at the LHC and compared their results to theoretical predictions and event generators.

 Angular analysis and CP violation studies in B decays at CMS / Chen, Kai-Feng (Taiwan, Natl. Taiwan U.) /CMS Collaboration Angular distributions of the decay $B^0 \to K^{*0} \mu^+\mu^-$ are a clean probe of physics beyond the standard model. In particular the forward-backward asymmetry and other variables which can be determined as a function of $q^2$, provide fruitful information from a single decay channel.

 Study of heavy flavour and vector bosons associate production at CMS / Candelise, Vieri (INFN, Trieste ; Trieste U.) /CMS Collaboration The mechanism of production of heavy-flavoured mesons, containing b or c quarks, in association with vector bosons, W or Z, in the Standard Model is only partially understood. The study of events with one or two well-identified and isolated leptons accompanied by b-jets or secondary vertices is therefore crucial to refine the theoretical calculations in perturbative QCD, as well as validate associated Monte Carlo techniques.
