LAPTh, an overview
LAPTh is a mixed research unit (UMR 5108) of the CNRS (within the Institute of Physics, INP) and the Université de Savoie. It is located in Annecy-le-Vieux, 5km from the centre of Annecy and about 40km from CERN and Geneva. The activities of LAPTh are centred around three main areas of research:
Post-doc Position to be filled Fall 2017 : Precision Calculations
In the framework of the French Excellence Initiative, ENIGMASS, a consortium of the four laboratories (LAPP, LAPTh, LPSC and LSM), we are seeking candidates for a post-doctoral position at LAPTh Annecy to work on the topic of precision calculations (QCD and electroweak higher order corrections) with applications to LHC physics. A good knowledge or familiarity with Monte-Carlo generators, tools or techniques will be a bonus. The successful candidate will join a team of theorists at LAPTh. Collaboration with theorists at LPSC Grenoble and with experimentalists in ATLAS (LAPP Annecy and LPSC Grenoble) is foreseen.
The fellowship is awarded for a period of two years starting in Fall 2017.
Applications will be reviewed starting Dec. 11th 2016, it is therefore highly advisable that the recommendation letters have reached by then. Submissions will remain open until the position is filled. Apply here.
Post-doc Position to be filled Fall 2017 : Flavour Physics
The theoretical high-energy physics (HEP) group at the LAPTh Annecy invites applications for a postdoctoral position funded by the French Excellence Initiative ENIGMASS (consortium of the four laboratories LAPP and LAPTh in Annecy, LPSC in Grenoble and LSM in Modane). The fellowship is awarded for two years, starting fall 2017. We are seeking a candidate whose research interests have substantial overlap with flavor physics. Close interaction with the LHCb group at the adjacent LAPP building is foreseen. However, applicants from all areas of high-energy phenomenology are encouraged to apply.
The LAPTh HEP group activities have large overlap with the astro-cosmo group. The lab also enjoys very close interaction with LAPP Annecy (experimentalists) and LPSC Grenoble (experimentalists/theorists), as well as with other CNRS labs, and with the nearby CERN. Annecy is a beautiful small-size town, located in a uniquely attractive area around a lake surrounded by mountains.
Interested candidates should submit their applications online here.
Required documents include a CV, a list of publications, a research statement, as well as three letters of recommendation.
The application deadline is Dec. 12, 2016. Later applications will be considered only if the position has not yet been filled.
First Franco-Russian Doctorate, initiated by LAPTh
Last June, the signing of the first Franco-Russian doctorate was held at the French Embassy in Moscow. The partners of this agreement, initiated by Pascal CHARDONNET of LAPTh, are the Université Savoie Mont Blanc, the Université Grenoble-Alpes, the COMUE Grenoble-Alpes, the Keldysh Institute of Applied Mathematics and the MEPhI in Moscow.
The objectives of the PhD in Fundamental Physics are:
The first joint doctoral training school will be held in Moscow on 12-16 December this year, which coindices with the 50th anniversary of Franco-Russian scientific cooperation. The theme will focus on the structure and evolution of the universe. The LAPTh welcome also the first student of the doctorate starting November 2016, on the understanding of the dark age of our universe with the formation of its first stars.
The IDEX project Université Grenoble Alpes is selected !
The conglomerate of academic institutions united by the Grenoble Alpes University Community (UGA) has been selected winner of the Excellence Initiative (IDEX) by an international jury chaired by Jean-Marc Rapp. The project submitted by the COMUE "Communauté Université Grenoble Alpes" under the programme "Investments for the Future" aims at creating a world-class university, with a strong international reputation, founded on scientific excellence, dynamism of its ecosystem, the leading rôle in educational innovation and student success, the involvement and commitment of the socio-economic and cultural world and local authorities. This date will mark a new beginning for the new institution and will be a major boon for all the laboratories involved. For LAPTh this will reinforce our contribution to the Excellence Laboratory Initiative (Labex) Enigmass and build upon our efforts in building a strong collaboration with the laboratories of the site in the framework of the UGA scientific clusters. More details on the UGA Idex project can be found here (in French).
International Indo-French Laboratory: IFTHEP
LAPTh (F. Boudjema) is coordinating an Indo French Laboratory, LIA (Laboratoire International Associé). The Indian coordinator is Rohini Godbole of the IISc (Indian Institute of Science) in Bangalore. The set up of the LIA is well timed since it covers the physics of the LHC, the LHC has just started colliding beams to achieve the unprecedented total centre of mass energy of 13TeV. After the discovery of the Higgs we are hoping that the opening up of this new threshold will allow discoveries that will shed light on the mysteries of the Higgs and provide clues about dark matter. The other major topic of the LIA is the study of the quark gluon plasma which intimately should provide clues about how matter forms in extreme conditions.
The LIA is structured around 4 nodes in each country. Participating laboratories represent the leading theory groups in both country with a high visibility internationally. The French laboratories are LAPTh, LPSC Grenoble, IPN Lyon, LPT Orsay, CPhT (Ecole Polytechnique) and IPhT CEA Saclay. On the Indian part beside IISc we have TIFR Mumbai, SINP/IACS/IISER Kolkata, IMSc Chennai and HRI Allahabad. The LIA IFTHEP (Indo French Theory High Energy Physics) , will run for an initial period of 4 years.
Refined background calculations for AMS02
The latest results from the AMS-02 experiment were announced in mid-April at CERN. These were the most precise measurements to date concerning the fluxes of protons, helium and the antiproton-to-proton ratio, extending at the same time the energy range of the PAMELA experiment. Most awaited were the results concerning the production of anti-matter, in particular the measurement of the anti-protons since the latter can be produced by the annihilation of Dark Matter particles which constitutes therefore a primary source. The conventional Standard Model production of anti-protons is through the collisions of high-energy cosmic rays with interstellar matter. This mechanism is therefore a secondary production mechanism that constitutes an important background to the signal of new physics through Dark Matter detection. Previous estimates of this background predicted a steep decrease at high energy (hundreds of GeV) of the antiproton-to-proton ratio.
The UGA Idex project pre-selected
Université de l’innovation
An important hurdle has been crossed on the way to achieve the goal of establishing the UGA, Université Grenoble Alpes, as a world class research and innovation university. The UGA is a conglomerate of universities and research institutions with a multi-disciplinary training programme in Grenoble and in the Alps region. The French Ministry of Education and Research has announced that the Idex (Excellence Initiative) pre-project of UGA is one out of three pre-projects that has been selected among 7 other applications. This paves the way to the submission of the full project which will be reviewed by an international panel whose results will be made public in January 2016. In case of success this date will mark a new beginning for the new institution and will be a major boon for all the laboratories involved. For LAPTh this will reinforce our contribution to the Excellence Laboratory Initiative (Labex) Enigmass and build upon our efforts in building a strong collaboration with the Grenoble laboratories.
More details on the UGA Idex project can be found here (in French).
The project stands on excellent scientific foundations. For example, 1 out of 5 inhabitants in the Grenoble Alpes region are, in one way or the other, involved with research and innovation, see this short clip .
Lectures on Amplitudes and Symbols
With 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.
