Flavor Physics and Neutrinos
Parallel Session talk
In this work we consider a simple extension of the Standard Model involving additional fermionic singlets and assume an underlying inverse seesaw mechanism for neutrino mass generation. In a first stage we determine which are the minimal inverse seesaw realisations that account for neutrino data while at the same time complying with all experimental requirements (electroweak precision tests...

Flavor Physics and Neutrinos
Parallel Session talk
I will present a model where spontaneous breaking of global lepton number within the seesaw mechanism leads
to a consistent inflationary scenario consistent with the recent CMB B-mode observation by the BICEP2 experiment.
The model includes a natural dark matter candidate and can account for the baryon asymmetry of the universe through leptogenesis.

Cosmology and Astroparticles
Parallel Session talk
I present extensions of the Standard Model, where the global symmetries baryon and lepton number are gauged and subsequently spontaneously broken. These theories are consistent with collider bounds and cosmology, and have intriguing consequences due to the requirement of anomaly cancellation: lepto-baryon fields that have to be introduced can be a dark matter candidate and/or generate neutrino...

Flavor Physics and Neutrinos
Parallel Session talk
Based on flavour symmetries only, there are two ways to give rise to an effective description of flavour physics in the quark sector close to the CKM picture: one is based on $U(3)_q\times U(3)_u\times U(3)_d$, and the other on $U(2)_q\times U(2)_u\times U(2)_d$ (or equivalent symmetries). In this context we analyze the current status of flavour physics measurements and we compare their...

Flavor Physics and Neutrinos
Parallel Session talk
We derive bounds on the electric and chromo-electric dipole moments of the charm quark. The second one turns out to be particularly strong, and we quantify its impact on models that allow for a sizeable flavour violation in the up quark sector, like flavour alignment and Generic U(2)^3. In particular we show how the bounds coming from the charm and up CEDMs constrain the size of new physics...

SuSy and other BSM phenomenology
Parallel Session talk
In supersymmetric models, a CP-even state with SM Higgs couplings mixes with additional, heavier CP-even states, causing deviations in the Higgs couplings from SM values. These deviations are reduced as the heavy states are decoupled with large soft masses, thereby exacerbating the tuning associated with the electroweak scale. This new source of tuning is different from that derived from...

SuSy and other BSM phenomenology
Parallel Session talk
We discuss a class of models based on a few-site deconstruction of an AdS5 background. We show how the separation between the Planck and weak scales may be obtained as well as the hierarchies of fermion masses. Being weakly coupled, these models have supressed contributions to flavor violation and electroweak precision parameters.
In addition, we discuss how the Higgs may be realized as a...

SuSy and other BSM phenomenology
Parallel Session talk
We study the phenomenological implications of a string-motivated scenario in which supersymmetry breaking is triggered by the Dilaton field. We show that for the MSSM there is a tension between the expected Higgs mass and the dark matter relic abundance. This constrains the parameter space and thus leads to testable predictions for LHC-14. We also present examples within the general singlet...

SuSy and other BSM phenomenology
Parallel Session talk
In light of the conspicuous absence of SUSY in the energy range explored by the
LHC in 2012, non-supersymmetric BSM scenarios are becoming more and more
attractive. One key ingredient in exploring such BSM physics are the
renormalization group equations (RGEs) that are essential for extrapolating the
theory to higher energy scales. Although the 2-loop RGEs for a general quantum
field...
