Precision Gauge Unification from Extra Yukawa Couplings

Friday October 1st, 14:30 hs -  Seminar room

Speaker: Arthur Hebecker (University of Heidelber)

Abstract:

Extra vector-like GUT multiplets can have a significant impact on the predicted value of the strong coupling. In particular, Yukawa couplings between such extra multiplets and the MSSM Higgs doublets can resolve the familiar two-loop discrepancy between the SUSY GUT prediction and the measured

Minimal Conformal Technicolor and Precision Electroweak Tests

Tuesday September 21st, 14:30hs - Seminar room

Speaker: Ruggero Tacchi (University of California, Davis)

 

Abstract:

I will talk about the minimal model of conformal technicolor and how the electroweak symmetry breaking is delivered in this theory. The chiral symmetry breaking follows the pattern SU(4) --> Sp(4) and generates two uneaten pseudo-Nambu-Golstone bosons: a composite Higgs and an additional neutral

Low Scale Flavor Gauge Symmetrie

Friday September 17th, 14:00hs - Seminar Room

Speaker: Giovanni Villadoro (CERN, Geneva)

 

Abstract:

I will discuss the possibility of gauging the Standard Model flavor group. Anomaly cancellation leads to the addition of fermions whose mass is inversely proportional to the known fermion masses. In this case all flavor violating effects come out to be controlled roughly by the Standard Model Yukawa, suppressing transitions for the light generations. Due to the inverted hierarchy the scale of new gauge flavor bosons could be as low as the electroweak scale without violating any existing bound but accessible at Tevatron and LHC. The mechanism of flavor protection potentially provides an alternative to Minimal Flavor Violation, with flavor violating effects suppressed by hierarchy of scales rather than couplings.

THESIS DEFENSE - TeV gamma-ray observations of nearby Active Galactic Nuclei with the MAGIC telescope: exploring the high energy region of the multi-wavelength picture

Friday July 23rd 2010, 12 pm - Seminar room

Thesis Defender: Diego Tescaro

Partially Supersymmetric Composite Higgs Models

Friday July 16th, 14:30hs - Seminar room

Speaker: Michele Redi ( CERN Geneva)

Abstract:

I will discuss the idea of the Higgs as a pseudo-Goldstone boson within the framework of partial supersymmetry in Randall-Sundrum scenarios and their CFT duals. The Higgs and third generation of the MSSM are composites arising from a strongly coupled supersymmetric CFT with global symmetry SO(5)

Beautiful Mirrors at the LHC

Friday July 9th, 14:30h - Seminar Room

Speaker: Roberto Vega-Morales (Northwestern University)

Abstract: In this talk I will explore the "Beautiful Mirrors" model, which aims to explain the measured value of A^b_FB, discrepant at the 2.9sigma level. This scenario introduces vector-like quarks which mix with the bottom, subtly affecting its coupling to the Z. The spectrum of the new particles consists

Cosmic-ray signatures of dark matter decay

Monday July 5th, 12:00 hs - Seminar room

Speaker: Alejandro Ibarra  (Technische Universität München)

Variations on Minimal Flavour Violation

Friday July 2nd, 2010, 14.30 hs - Seminar room

Speaker: Thorsten Feldmann (Technische Universitat Munchen)

Abstract: In this talk I will present some recent applications and extensions of the concept of "minimal flavour violation" (MFV), which is frequently used to constrain the flavour sector of new physics models. I will shortly explain how to define MFV in the effective-theory context, making use of Yukawa

A Warped Model of Dark Matter

Friday June 25th, 14:30 - Seminar room

Speaker: Benedict von Harling (University of Melbourne)

 

Abstract:
We present a model of dark matter in a warped extra dimension in which various dark sector mass scales are naturally generated without supersymmetry. The dark matter, whose mass is in the TeV range, is charged under a dark abelian gauge group. The corresponding dark photon obtains a mass in the
