Alessandro Torrielli (University of Surrey, United Kingdom) will visit IGFAE and he will give lectures in the week 16th-20th September. The course will be about 10 hours in total. He will teach on the topic of classical integrability. To get an idea you may see his lecture notes at https://arxiv.org/abs/1606.02946. For more information, please, contact Riccardo Borsato (riccardo.borsato@usc.es). More information coming soon!

The organizing committee cordially invites you to attend the Topical Workshop on Electronics for Particle Physics (TWEPP). The conference will be held in the historic city of Santiago de Compostela from September 2nd to 6th, 2019.

The scientific program focusses on all aspects of electronics for particle physics experiments, and accelerator instrumentation. LHC experiments (and their operational experience) remain a focal point of the meeting but a strong emphasis on R&D for future experimentation will be maintained.

Several renowned keynote speakers will give their view on new ground breaking developments in this field. Additionally, researchers are invited to submit abstracts, based on which, a variety of presentations and poster sessions will be held.

Further informal discussions concerning the different conference topics will be possible during the conference welcome reception, the dinner and any other social opportunity offered by the beautiful city of Santiago.

Let us extend to you a warm welcome to Santiago and to TWEPP!

We shall discuss Chern-Simons (CS) theories with rank N and level k on generic three manifold. The partition functions of such theories can be written as a function of modular transformation matrices summed over different integrable representations of affine Lie algebra u(N)k. Using properties of modular transform matrices, we express the partition functions of these theories as a unitary matrix model. We show that, the eigenvalues of unitary matrices are discrete and proportional to hook lengths of the corresponding integrable Young diagram. As a result, in the large N limit, the eigenvalue density develops an upper cap. We consider CS theory on S2 × S1 coupled with fundamental matters and express the partition functions in terms of modular transformation matrices. Solving this model at large N we find the dominant integrable representations and show how large N representations are related to each other by transposition of Young diagrams as a result of level rank duality.

Next we consider U(N) CS theory on S3 and observed that in a particular framing the dominant representation is no longer an integrable representation after a critical value of ’t Hooft coupling. We also show that CS on S3 admits multiple (two-gap phase) large N phases with the same free energy.

The conference will bring together experts working on different topics of string theory, including integrable deformations, non-abelian/Poisson-Lie T duality and double field theory. The schedule of the talks will allow for extended time dedicated to discussions among participants.

The Iberian Gravitational Waves Meeting, (IberianGW2019) is an international conference organised yearly by different members of the Red Temática de Ondas Gravitacionales (REDONGRA). In 2019 it will take place in Santiago de Compostela, organized by the Instituto Galego de Física de Altas Enerxías, IGFAE.

In the mid-2020s, Fermilab will commission the world’s most powerful neutrino beam. The Long-Baseline Neutrino Facility (LBNF) will provide the neutrino beam for the Deep Underground Neutrino Experiment (DUNE), whose large (40kT) liquid argon detectors will be located in the Homestake mine in Lead South Dakota, 1300 km from Fermilab. On the Fermilab site, the Near Detector Hall will be located at a depth of approximately 200 feet beneath surface level and will house 3 detector systems that will enable the full reach of the DUNE physics program. In a sense, the near site could be called the Fermilab Accelerator-Neutrino Observatory (FANO), given the enormous number of neutrino events (upwards of 100M events per year) that can be studied there. In this talk I will give a brief overview of the goals of the DUNE program and the neutrino beam provided by LBNF and then go into detail on the near detectors. I will focus the near detector discussion, however, on the Multi-purpose Detector (MPD) component. The MPD, which consists of a large gaseous Time Projection Chamber operating at 10 Atm surrounded by a high-performance electromagnetic calorimeter, both housed in a large magnet system operating at 0.5T magnetic field, is the first direct application of collider-detector technology and configuration to a neutrino experiment. Finally, I will outline the physics program beyond DUNE’s core oscillation physics that can be performed at the near site.

In this informal presentation I will provide a concise introduction to some of the fundamental objects in classical integrability. Maintaining focus on the concepts, we will work within the principal chiral model representing a string on a 3-sphere.

In this talk, I will present the results for the computation of the spin-2 excitations for a class of N=2 supersymmetric solutions of type IIA supergravity found by Gaiotto and Maldacena. The mass spectrum of these excitations can be derived by solving a second order partial differential equation. In our work, we consider as specific examples the Abelian and non-Abelian T-dual versions of AdS5xS5 and we study the mass spectra. For the modes that do not "feel" the non-Abelian T-duality transformation, we can provide analytical formulas for the masses, while for the rest we can only derive the spectra numerically. The numerical values that correspond to large masses are compared with WKB formulas. We also find a lower bound for the masses.

The 2nd edition of the joint Workshop LIP/IGFAE consolidate the long tradition of scientific cooperation between researchers from the two institutes, both national and international references on High-Energy Physics. It follows the previous edition

In this blackboard talk I will give a pedagogical introduction to the so-called T-Tbar deformations. This is a class of irrelevant deformations of two-dimensional quantum field theories generated by the determinant of the stress-energy tensor. Remarkably, such deformations preserve a wealth of symmetries of the underlying theory, and they act in a simple way on the spectrum of any QFT. Though their physics is far from being completely understood, they seem to be closely related to string theory, to the holographic "AdS/CFT" duality, and to flux tubes in gauge theory. I will review some of these links and give some personal remark on those which I found most intriguing.
