2. Status of Higgs Effective Theories

Luca Merlo (IFT, Madrid)

With the discovery of a scalar resonance at ATLAS and CMS, the understanding of the electroweak symmetry breaking origin seems a much closer goal. Deviations from SM couplings are different for theories of new physics based on a non-linear realisation of the SU(2)xU(1) gauge symmetry breaking and those assuming a linear realisation. In this talk, I will review and compare the effective...

1. SUSY custodial Higgs triplets and breaking of universality

Mariano Quiros (IFAE, Barcelona)

24/10/14 10:15

An extension of the MSSM with Higgs triplets can be of great help to alleviate the little hierarchy problem. We show that such an extension (a supersymmetric version of the Georgi-Machacek model) in agreement with electroweak data does exist. The main smoking gun of the model, apart from the rich phenomenology with singly and doubly charged scalars and fermions, can be the possible breaking of...

0. Seesaw scale vs Cosmology

Jacobo Lopez Pavon (SISSA, Trieste)

24/10/14 11:30

I will study the simplest extension of the SM that can account for neutrino masses: the Type-I seesaw. The model introduces a New Physics scale, M, which is often assumed to be much larger than the electroweak scale. However, it is presently unconstrained and the light neutrino masses and mixing can be generated for any value of M above eV. Its determination is one of the most important open...

3. Cosmology and fundamental physics: some examples

Licia Verde (ICC, Barcelona)

24/10/14 12:15

Cosmology has made the transition to precision science. This opens up the possibility to test fundamental physics with cosmological observations. I will present some examples and discuss potential and challenges of this approach.

4. Theoretical Status of Inflationary Cosmology

Lotfi Boubekeur (IFIC, Valencia)

24/10/14 14:45

Inflation is by far the leading theory explaining the initial conditions of our universe. Its predictions are consistent with all existing experimental probes, yet it lacks firm observational evidence. I will give an overview of the theoretical status of inflationary scenarios, in a model-independent way. I will explain how inflationary predictions are related to fundamental physics and what...

5. Neutrino oscillation phenomenology: three-flavor analyses and beyond

María Amparo Tortola (IFIC, Valencia)

24/10/14 15:30

I will present an updated global fit to neutrino oscillation data within the three-flavour framework. The most recent data from solar and atmospheric neutrino experiments are included in our analysis together with the latest results from the long-baseline accelerator experiments T2K and MINOS and the recent measurements of reactor neutrino disappearance reported by Double Chooz, Daya Bay and...
