NewsLectures on Amplitudes and SymbolsWith the advent of the LHC and the need for ever increasing accuracy, techniques in loops calculations have witnessed tremendous progress borrowing from highly complex mathematical structures and improving and adapting these structures. A very recent development concerns the use of symbols. Giorgios Papathanasiou will introduce some of these concepts starting from an elementary exposition of how these objects appear from the integrals one encounters in the evaluation of scattering amplitudes beyond tree-level. There will be 4 lectures: 1: Analytic structure of scattering amplitudes and Feynman integrals. Algebraic and transcendental functions. Classical polylogarithms. 2: Multiple polylogarithms (MPL): Integral and Series representations. Shuffle and quasi-shuffle algebras. 3: The symbol map. Properties. Integrability condition. Application: Resolving identities among MPLs and simplifying expressions. 4: (Optional) Advanced topics: The Hopf algebra of MPLs and the coproduct. Bootstrapping amplitudes. Expanding the symbol. Graspa 2015Undergraduate Summer School in Particle and Astroparticle Physics of Annecy-le-Vieux, July 16-22 2015 The school Courses will be in English. No background knowledge on the topics covered beyond a popular science level is assumed. A strong background in Quantum Mechanics is expected, however.
A maximum of 30 students will be admitted. PhysTeV Les Houches 2015In a few weeks the high energy physics team will be going to Les Houches. We will be overseeing the 9th session of the LH PhysTeV. This session will coincide with the first beams at the LHC which will soon be running at 13TeV. The highlight of the 2015 Les Houches Edition is to take full advantage of the data that has been collected at the LHC so far and prepare for the future runs. The Workshop will devote particular attention to:(i) Higgs physics, and how it shapes our view on the mechanism of electroweak symmetry breaking; (ii) related searches for New Physics and (iii) progress in new techniques for the calculations and simulation of Standard Model processes. These activities will be conducted in close connection with the development and improvements of related theory tools, in particular of Monte-Carlo event generators. The Workshop proper runs over one year, including two meetings in Les Houches in the month of June, and exchanges and collaborations before and after the meetings. The meetings in Les Houches will consist of two sessions: Session I: 1-10 June 2015with emphasis on SM-related issues Session II: 10-19 June 2015 with emphasis on New-Physics searches A course on Nonequilibrium Processes
