SEMINAR: Radion-Dilaton/Higgs in light of the LHC

Friday April 4 2014, 2:30pm - Seminar room

Speaker: Anibal Medina (University of Melbourne)

Abstract:

Motivated by the bulk mixing $\xi R_5 H^{\dagger}H$ between a massive radion and a bulk scalar Higgs in warped extra dimensions, we construct an effective four dimensional action that---via the $AdS/CFT$ correspondence---describes the most general mixing between the only light states in the theory, the dilaton and the Higgs.

SEMINAR: Massive gravity and extensions

Friday March 28 2014, 2:30pm -  Seminar room

Speaker: David Pirtskhalava (Scuola Normale Superiore,Pisa)

Abstract:

A unique linear theory describing a free massive spin-2 representation of the Poincare group - Fierz-Pauli model - has proven to be extremely hard to generalize at the nonlinear level, without violating its consistency.

SEMINAR: Inflation, BICEP2, and an interesting discrepancy with Planck

Thursday March 27 2014, 12:00pm -  Seminar room

Speaker: Prof. Lorenzo Sorbo (U.Mass Amherst & TPT-CEA Paris)

Abstract: The BICEP2 collaboration has reported a strong B mode signal in the CMB polarization, which is well fit by a tensor-to-scalar ratio of r ~ 0.2.

COLLOQUIUM: High Energy Neutrino Astronomy at the South Pole

Monday March 24 2014, 12:00pm - Seminar room

Speaker: Kael Hanson (Universite Libre de Bruxelles)

Abstract: Abstract: The IceCube Neutrino Observatory at the South Pole Station is about to enter it's 4th year of operation with the full 86 string array (IC86).

SEMINAR: Backreaction in extended theories of gravity

Friday March 14 2014, 2:30pm -  Seminar room

Speaker: Alvaro de la Cruz Dombriz (UCM)

Abstract: One possible explanation for the present observed acceleration of the Universe is the breakdown of homogeneity and isotropy due to the formation of non-linear structures.

SEMINAR: On the non-linear scale of cosmological perturbation theory

Thursday March 20 2014, 2:40pm - Seminar room

Speaker: Thomas Konstandin (DESY)

Abstract:

I discuss the use of perturbative methods to study the evolution of matter fluctuations in the context of large scale structure formation.

SEMINAR: Non-relativistic particles in a thermal bath

Friday March 7 2014, 2:30pm -  Seminar room

Speaker: Antonio Vairo (Munich Tech. U)

Abstract:Heavy particles provide an ideal window for new physics and new phenomena. Since the late eighties they are treated by means of effective field theories that fully exploit the symmetries and power counting typical of non-relativistic systems.
