SUMMARY:Hongtao Yang (CERN) "ATLAS Measurement of Higgs Boson Production in the Diphoton Decay Channel and ATLAS-CMS Combined Measurement of the Higgs Boson Mass"
DESCRIPTION:Abstract:\nUnderstanding the properties of the newly-discovered Higgs boson has been one of the priorities of the LHC physics program. In this talk\, I will present the measurement of Higgs boson production processes in the diphoton decay channel using 4.5/fb of pp collisions at 7 TeV and 20.3/fb at 8 TeV collected by the ATLAS experiment at the LHC\, and discuss the essential role of this decay channel in the Higgs boson coupling studies. I will also cover the measurement of Higgs boson mass based on the combined data samples of the ATLAS and CMS experiments in the high resolution diphoton and four-lepton decay channels.

SUMMARY:Lene Bryngemark (Lund U.) " Searches for Physics Beyond the Standard Model Using Dijets in ATLAS"
DESCRIPTION:Abstract:\nThe LHC gives us access to the highest collider energies\, at the highest intensities\, providing a unique opportunity to thoroughly examine the constituents of matter and their interactions at ever smaller distances and higher mass scales. Jets are produced in the highest momentum transfer collisions and are thus at the energy frontier. With the recent increase in LHC beam energy\, ATLAS makes use of this sensitivity to make its first statements of what physics looks like in a new energy regime. In this presentation\, I show the results from both the 8 and the more recent 13 TeV analysis of dijet mass and angular distributions. I also mention some possible extensions of this analysis to further enhance its discovery potential for physics beyond the Standard Model.

SUMMARY:Ben Nachman (SLAC) "Measuring and Exploiting the Quantum Properties of Jets with the ATLAS Detector"
DESCRIPTION:Abstract:\nQuarks and gluons hadronize before their properties can be directly measured.  However\, information about the origin\, electric charge\, and color charge of high energy quarks and gluons is embedded in the resulting collimated sprays of hadrons known as jets.  This information defines the quantum properties of jets: the observable consequences of the quantum properties of quarks and gluons on the jets they form.  Such properties are often subtle\, but the ATLAS collaboration has recently demonstrated that even the electric and color charge can be extracted with high precision.  These measurements have important implications for probing the emergent properties of the strong force at the highest available energies and for searching for physics beyond the Standard Model.

SUMMARY:Special RPM - Rachel Mandelbaum (CMU) "Recent Progress and Future Prospects for Weak Lensing Cosmology""
DESCRIPTION:Abstract:\nMeasurements of weak gravitational lensing (coherent shape distortions of distant galaxies due to the lensing effect of mass between us and those galaxies) and are among the most promising ways to learn about the equation of state of dark energy\, the theory of gravity on cosmological scales\, and the connection between galaxies and the dark matter density field.  In this talk\, I will review the state of the field of weak lensing\, including recent cosmological analysis and prospects with future surveys.  I will then discuss some of the obstacles to robust weak lensing cosmology\, such as the difficulty in estimating coherent galaxy shape distortions in real data\, or in removing the effect of coherent galaxy shape alignments that arise due to (for example) large-scale tidal fields.  After presenting recent progress on both of these sources of systematic uncertainty\, I will conclude with future prospects for reducing them to below the statistical error and enabling robust cosmological constraints with future large surveys such as LSST\, Euclid\, and WFIRST.
