Some experimental anomalies suggest the possible existence of light sterile neutrino(s) mixing with the active ones. In this talk, we present a (supersymmetric) scenario in which the sterile neutrino is the fermionic partner of the pseudoGoldstone boson associated with the spontaneous breaking of an approximate global symmetry. This property protects the sterile neutrino mass against large contri

We propose an extension of the standard model in which dark sector respects an unbroken local U(1) symmetry and communicates with standard model sector via portal interactions of Higgs, righthanded neutrinos and kinetic mixing. Various constraints and physics involved in the model are discussed.

I study precision gauge coupling unification (PGU) in the MSSM with pure gravity and mixed gravity/anomaly mediation. Implications of PGU for SUSY searches at the LHC are discussed.

We present the formalism of computing oneloop effective action for quantum gravitation using nonlocal heat kernel methods. We find agreement with previous old results. In main part of my talk I consider the system of EH gravitation and scalar fields. We are able to derive nonlocal quantum effective action up to the second order in heat kernel generalized curvatures. By going to flat spacetime e

I will present ideas of how to predict fermion mixing with the help of discrete nonabelian flavor symmetries which are broken in a particular way and give examples of models in which such ideas are realized. In the leptonic sector emphasis will be put on the possibility to explain the recently measured value of the reactor mixing angle and the possibilities to predict CP violating phases.

The motivation behind flavourmessenger unification originates from some Ftheory constructions of GUT theories where flavour and messengers come from the same D7brane intersection. This means that messengers and visible matter should be treated on equal footing. This scenerio has very strong consequences on model building and low energy phenomenology.

As is well known, a standard heterotic compactification to a maximally symmetric spacetime does not allow for fluxes to stabilise moduli. By relaxing the condition of a maximally symmetric spacetime, I show how this nogo theorem may be avoided. I will work with the example of a domain wall for concreteness. After moduli stabilisation, the domain wall vacuum may be lifted by means of e.g nonpert

Scenarios in which the supersymmetry breaking scale is not far above the soft parameters of the Minimal Supersymmetric Standard Model (MSSM) have two main consequences for model building. First, the particle spectrum is extended by an almost massless gravitino and possibly a sgoldstino scalar. Second, the MSSM interactions receive significant corrections from higher dimensional effective operators

Recent discovery of Higgslike particle at the LHC points to modifications of standard gauge mediation models. Those which have attracted the most attention contain additional interactions between messengers and matter. During the talk I will discuss the role of such messengermatter couplings and give examples of lowenergy spectra in that class of models.

Dark radiation is produced in LARGE volume models in which reheating is driven by the volume modulus decaying to the visible sector. Decays of this modulus to its axion partner provide the dark radiation. I will discuss the effects of oneloop radiative corrections to the only competitive MSSM decay channel: the decay into Higgs pairs via the GiudiceMasiero term. This alone will more precisely de

The discovery of the Higgs candidate boson last year offers a new tool to investigate BSM physics. Models with warped extra dimensions involve an additional scalar, the radion, which can mix with the Higgs. This mixing has been previously considered for Higgses localised on the infrared brane. We extend these studies to two further classes of models: those with a bulk Higgs, and gaugeHiggs unific

An appealing proposition to explain the suppression of proton decay mediating and other operators, in heterotic string derived models, is the existence of a low scale $Z^\prime$ that forbids the undesired operators, and thus may arise only after $Z^\prime$ breaking. We will discuss the constraints on such a $Z^\prime$ arising in string derived models and focus on the constraints arising from gauge

Supersymmetry breaking and its mediation can be reformulated as a scattering problem. This talk will outline how pion scattering and "bottom up" AdS/QCD models may be extended to describe strongly coupled hidden sectors that break supersymmetry. We look at what can "inprinciple" be measured and what it can actually predict about the MSSM.

We construct supersymmetric $SO(10)$ models with different intermediate scales, consistent with gauge coupling unification. We found the complete list of sets of fields that can be added in each regime that allows to preserve unification and a "sliding scale mechanism". Using mSugra boundary conditions we calculate some particular combinations of soft SUSY breaking terms, called "invariants", that

The Higgs quartic coupling has now been indirectly measured at the electroweak scale. Assuming no new lowscale physics, its running is known and, together with gauge and Yukawa couplings, it is a crucial new piece of information constraining UV completions of the Standard Model. In particular, supersymmetry broken at an intermediate or high energy scale with low tan(beta) is consistent with prese

We study the phenomenological viablility of a constrained NMSSM with parameters subject to unified conditions from Ftheory GUTs. We find that very simple assumptions about modulus dominance SUSY breaking in Ftheory unification lead to a predictive set of boundary conditions , consistent with all phenomenological constraints.

The Goldstone theorem does not apply straightforwardly to the case of spontaneously broken spacetime symmetries such as dilatation invariance. We elucidate under which conditions a light scalar degree of freedom, identifiable with the dilaton, can naturally arise in a field theory. Our construction can be considered as an example of an explicit dynamical solution to the Cosmological Constant probl
