SEMINAR: Dark matter and flavor

Decemeber 18 2014, 2:30pm - Seminar room

Speaker: Fady Bishara (Cincinnati U and Fermilab)

Abstract : We show that flavor symmetries can lead to dark matter stability without the need to impose additional discrete or continuous symmetries specifically for this purpose. We explore two scenarios.

December 12 2014, 2:30pm -  Seminar room

Speaker: Lorenzo Ubaldi (Bonn U)

Abstract : The axion represents a plausible solution to the strong CP problem, while supersymmetry remains a leading candidate in addressing the hierarchy problem of the Standard Model. Marrying the axion with supersymmetry results in a very rich and interesting phenomenology.

SEMINAR: On Flavour and Naturalness of Composite Higgs Models

December 11 2014, 2:30pm -  Seminar room

Speaker: Alexei Matsedonskyi (SNS Pisa)

Abstract : In this talk I present an analysis of flavour and EWPT constraints imposed on Composite Higgs models with a flavour-symmetric strong sector.

SEMINAR: Standard Model vacuum stability with a 125 GeV Higgs

December 5 2014, 2:30pm -  Seminar room

Speaker: Stefano Di Vita (MPI Munich)

Abstract : The observation at the LHC of a scalar particle compatible with the Standard Model (SM) Higgs boson could represent the ultimate success of the SM description of particle interactions.

SEMINAR: Understanding the Large Scale Structure of the Universe through Symmetries

November 28 2014, 2:30pm -  Seminar room

Speaker: Toni Riotto (Geneva U)

Abstract : Getting inspiration from what is usually done in high energy physics, we will discuss what kind of knowledge we may get on the large scale structure of the universe from the symmetries of the dark matter dynamics.

SEMINAR: Atomic dark matter

November 25 2014, 12:00pm - Seminar room

Speaker: Kalliopi Petraki (NIKHEF Amsterdam)

Abstract : Observations of the galactic and subgalactic structure of our universe can be explained better if dark matter possesses sizeable self-interactions, rather than if it is collisionless.

SEMINAR: A Higgs or the Higgs ? A detailed look at the anomalous Higgs couplings

November 21 2014, 2:30pm - Seminar room

Speaker: Shankha Banerjee (HRI Allahabad India)

Abstract : Recent results from the Large Hadron Collider (LHC) has proved the existence of the long-awaited Higgs boson in the Standard Model (SM).

SEMINAR: Massive gravity from spontaneous symmetry breaking

November 14 2014, 2:30pm -  Seminar room 

Speaker: Diego Blas (CERN)

Abstract : In this talk I'll present the first proposal to give mass to the gravitons from a spontaneous symmetry breaking mechanism. In contrast to massive gauge bosons, both the broken and unbroken phases are not Lorentz invariant.

SEMINAR: Models with small cosmological constant at finite temperature

November 11 2014, 2:30pm - Seminar room 

Speaker: Bithika Jain (Syracuse U)

Abstract : In 5D holographic realizations of spontaneously broken approximate conformal invariance, a naturally light dilaton can be obtained via the introduction of the small dependence of the 5D scalar potential on the field itself.

SEMINAR: News From Muonic Atoms

October 31 2014, 2:30pm -  Seminar room 

Speaker: Aldo Antognini (ETH Zurich)

Abstract : Muonic atoms are atomic bound states of a negative muon and a nucleus. The muon, which is the 200 times heavier cousin of the electron, orbits the nucleus with a 200 times smaller Bohr radius.
