The DRSTP Postgraduate AIO/OIO School 2015
Theoretical High Energy Physics (THEP)
will be held for the third time in collaboration with the
Jorge André Swieca/IFT Summer School
26 January - 6 February 2015
Săo Paulo, Brazil


First week:

Ana Achúcarro (Leiden University, the Netherlands): From inflation to dark energy
Abstract: The course will present the concepts of modern cosmology and the great advances made during the last decade, both theoretically and observationally.

Cliff Burgess (McMaster University, Canada): Physics beyond the standard model
Abstract: The goal of the lectures is to present generic BSM ideas that could be relevant to the physics of the LHC, and that could help understanding the phenomenon of Electroweak Symmetry Breaking, as well as other open questions in the Standard Model of Particle Physics.

Carlos Nuñez (Swansea University, UK): Lectures on gauge/gravity duality
Abstract: The goal is to introduce the fundamental properties of the AdS/CFT duality through models that have a well-defined construction within superstring theory.

Second week minicourse lectures:

Nima Arkani-Hamed (IAS Princeton,New Jersey, USA):Scattering amplitudes and the amplituhedron
In these lectures, a new formulation for scattering amplitudes in planar N=4 SYM will be described where the usual picture of unitary evolution though space-time is not primary. Instead, amplitudes are associated the “the volume” of a new geometric object, “the Amplituhedron”, closely connected to another object studied by algebraic geometers and physicists in recent years, known as “the Positive Grassmannian”. It wil be described how locality and unitarity arise as derived notions from the positive geometry.
The following reading material is recommended:
(1) There is an excellent review of scattering amplitudes by Elvang and Huang, arXiv:1308.1697
(2) The Introduction of this early paper of Arkani-Hamed and Cachazo, arXiv:0808.1446
(3) The positive grassmannian paper arXiv:1212.5605
(4) The amplituhedron paper arXiv:1312.2007

Jan de Boer (University of Amsterdam, the Netherlands): Entanglement entropy and its uses
In these lectures we first review a few basic notions from quantum information theory with an emphasis on entanglement and its properties. We then discuss properties of entanglement in various systems, how they can be used to diagnose various phases, and how it can be computed in weakly and some strongly coupled field theories. Finally, we will discuss some aspects of the relation between entanglement and space-time geometry that has emerged in recent years.
