Observation of top-quark production in the forward region with LHCb / Coco, Victor (speaker) (CERN)
As differential NNLO theory predictions become available, both single top and top pair production cross-section measurements in the forward region will provide important experimental tests. Top pair production in the forward region can also constrain the gluon density function in the proton at large momentum transfer, which are responsible for large uncertainties in many SM predictions.  Forward top production is observed, in the µ +b final state, with the  3 fb-1 Run I dataset collected by the LHCb detector. The cross-section for the combined t\bar{t} and single-t at \sqrt{s}=7 TeV and \sqrt{s}=8 TeV is derived, for muons from the W boson with pT>25 GeV in the pseudo-rapidity range 2.0<\eta<4.5 and with a b-tagged jet with 50<pT<100 GeV in the pseudo-rapidity range 2.2<\eta<4.2 [...]

Unlock performance secrets of next-gen Intel hardware / Dr. Matveev, Zakhar A. (speaker) (Intel Corp.)
Software must be optimized for both threaded and SIMD vector parallelism to achieve scaled performance on modern machines. The gap (often 2 orders of magnitude) between modernized workloads and unoptimized baselines is increasing with every next hardware generation. SIMD code modernization is not without cost, but exciting new features of OpenMP 4.0 "explicit vectorization" and new Intel® "Vectorization Advisor" software tool make it possible to introduce efficient and portable SIMD parallelism without disrupting ongoing development. In addition to vector parallelism topic, the seminar will cover adjacent "code modernization" areas like new types of memory available in Next Generation Intel® Xeon Phi Product. About the speaker Zakhar is a software architect in Intel SSG group [...]

Theories of Electroweak Symmetry Breaking : A Post LHC Run-I Perspective (1/3) / Wells, James Daniel (speaker) (University of Michigan (US))
Lecture 1 : The Brout-Englert-Higgs Theory of Electroweak Symmetry Breaking The goal of this lecture is to put the discovery of the Higgs boson in historical context and qualitatively discuss the importance and meaning of its discovery. Claims that the BEH theory has its roots in the theory developments of superconductivity will be considered [...]

Searching for hot new physics using ultracold neutrons: fundamental symmetries above the TeV scale. / Hickerson, Kevin (speaker) (UCLA)
 Ultracold neutrons (UCN) are an exotic variant of the familiar unbound nucleon, but down-scattered to 1 mK. At this temperature, UCN propagate extremely slowly, a few meters per second, with only a few 10-7 electron volts of kinetic energy [...]
