Geneva, 26 November 2010. After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe’s life.

 

The structure of 4D Conformal Field Theories

Friday November 26th, 14:30hs -  Seminar room

Speaker: Slava Rychkov  (ENS & UPMC, Paris)

Abstract:

I will review the status of the program, initiated a few years ago by the speaker and R. Rattazzi, of putting model-independent bounds on the structure of 4D CFTs by using OPE associativity and unitarity. I will also discuss applications to BSM phenomenology.

 

NOVEMBER 2011 - IFAE among the top ten Catalan research institutes

From La Vanguardia, November 17th 2010:

The emergence of Dirac Pyisics in Graphene

Tuesday, November 23rd, 14:00hs. - Coffee room

Speaker: Alessio Celi (UB)

Abstract:

After a very brief introduction to the genesis of the material and to the (apparent) clashing with the Mermin-Wagner theorem, I will show that many of the surprising experimental properties, like the relativistic dispersion relation of the quasi-electrons, can be easily explained by the tight-binding approx (Hubbard model).

Neutrinoless double beta decay: Neutrino mass versus exotic contributions

Friday, November 19th, 14:30 - Seminar room

Speaker: Martin Hirsch (IFIC, Valencia)

Abstract:

Neutrinoless double beta decay is a very sensitive probe for physics beyond the standard model. Usually it is discussed only as a probe for the (Majorana) neutrino mass scale but, in principle, any model with lepton number violation can contribute to its amplitude.

Discrete Symmetries and the Flavour Problem

Friday November 12th, 14.30hs - Seminar room

Speaker: Luca Merlo  (TUM, Munich)

Abstract:

The flavour puzzle is an open problem in the Standard Model and the use of new symmetries helps in explaining the fermion mass hierarchies and mixings as well as the (non-)observation of FCNC processes. I will review the main idea of the flavour model building with a particular attention to the discrete non-Abelian symmetries. Furthermore I will give few examples of possible strategies to test flavour models.

 

 

NOVEMBER 2010 - Postdoctoral Position at the IFAE theory group

The Theory Group at the Institut de Física d'Altes Energies (IFAE), on the UAB Campus (Barcelona) invites applications for a Postdoctoral Position in Theoretical Particle Physics starting in September 2011. The appointment will be for two years. A third year may be possible but will be subject to evaluation.

Holographic d-wave superconductors and spectral functions

Friday October 29th, 14:30hs -  Seminar room

Speaker: Francesco Benini  (Princeton University)


Abstract:

The properties of a superfluid phase transition with a d-wave order parameter in a strongly interacting field theory with gravity dual are considered. In the context of the AdS/CFT correspondence, this amounts to writing down an action for a charged, massive spin two field on a background, and I will

Constraining new physics contributions to the width difference in the B_s system

Wednesday, October 27th, 14:30hs - Seminar room

Speaker: Christian Bauer  (LBL, Berkeley)

Abstract:

The recent measurement of the di-muon asymmetry by the D0 collaboration is in excess of the SM prediction by 3.2 sigma. In this talk I will discuss the implementation of this measurement, and show that the central value is in violation with the SM prediction for the off-diagonal term in the decay matrix

OCTOBER 2010 - Postdoctoral position in the gamma-ray astrophysics group at IFAE

The gamma-ray astrophysics group at IFAE ( www.ifae.es ) in Barcelona is looking for candidates to fill a postdoctoral position in the frame of the MultiDark project (see below). The IFAE group is part of the MAGIC collaboration, which operates a system of two ground-based gamma-ray telescopes in the island of La Palma.
