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.

Effective Theory Predictions for LHC Processes

Monday, 25th October, 12:00hs - IFAE Seminar room.

Speaker: Christian Bauer  (LBNL, Berkely)

Abstract:

This talk will give an introduction to effective field theories and how they can improve our theoretical understanding of collider physics. After discussing the basic ideas of effective theories, I will present briefly a relatively new effective theory called SCET which is suitable for collider physics. I will then

Yang-Mills theory in 2+1 dim. (Schrödinger wave functional and Hamiltonian treatment by Karabali, Kim and Nair)"

Wednesday October 20th, 14:00hs - Multifunctional room

Speaker: Sebastian Krug

Abstract:

We review the treatment of 3 dimensional Yang-Mills theory in the fieldtheoretical Schrödinger picture done by Karabali, Kim and Nair, which gives an analytical continuum calculation of the vacuum wave functional, string tension, gluelump spectrum, etc. starting from first principles. For a review paper see hep-th/0309061.

Universal Extra Dimensions on (Projective) Sphere

Friday October 8th, 14:30hs - Seminar room

Speaker: Kin-ya Oda (Osaka University)

Abstract:

We propose a six dimensional Universal Extra Dimensions (UED) model compactified on a real projective plane $RP^2$, a two-sphere with its antipodal points being identified. We utilize the Randjbar-Daemi-Salam-Strathdee spontaneous sphere compactification with a monopole configuration of an extra
