SEMINAR: Heavy Vector Triplets: Bridging Theory and Data

May 9 2014, 2:30pm - Seminar room

Speaker: Andrea Thamm (EPFL Lausanne)

Abstract: I will discuss a model-independent strategy to study narrow resonances applied to a heavy vector triplet of the Standard Model group for illustration. The method is based on a simplified phenomenological Lagrangian which reproduces a large class of explicit models.

SEMINAR: BSM Primary effects

May 8 2014, 2:30pm - Seminar room

Speaker: Sandeepan Gupta

Abstract: While the predictions of the SM Lagrangian have by now all been tested, the experimental verification of the predictions of its dimension 6 extension are only begining, with the arrival of Higgs data. We first identify the BSM primary effects, the set of physical quantities, that give us the best way to constrain new physics.

COLLOQUIUM:  Hunting for Axions and WISPs with cutting-edge photon sensors

May 19  2014 - Seminar room

Speaker: Cantatore Giovanni (Trieste Universita & INFN)

Abstract: The search for Axions and for other WISPs, Weakly Interacting Slim Particles, has recently picked up considerable pace. Precision experiments looking for WISPs use a panoply of advanced techniques, explore a sector of particle physics outside the Standard Model in and are complementary to accelerator experiments.

SEMINAR: On the validity of effective field theory for dark matter searches at LHC

Friday May 16 2014, 2:30pm - Seminar room

Speaker: Enrico Morgante (U de Geneve)

Abstract:

Effective operators are a powerful tool for Dark Matter searches, because of their simplicity and because they provide a framework in which Direct Detection, Indirect Detection and collider experiments can put model independent constraints on the same space of parameters.

SEMINAR: A sterile neutrino at MiniBooNE, MicroBooNE and IceCube

Friday April 28 2014, 12:00pm

Speakar: Manel Masip (Universidad de Granada)

Abstract:We argue that a sterile neutrino of mass around 50 MeV slightly mixed with the muon flavor may be the origin of the MiniBooNE anomaly, and we study its implications at MicroBooNE (that starts taking data this year).

SEMINAR: Split SUSY Radiates Flavor

Friday April 25th 2014, 2:30pm -  Seminar room

Speaker: Daniel Stolarski (CERN)

Abstract: The discovery of a Higgs with mass around 125 GeV is in tension with natural supersymmetry (SUSY).

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).
