abstract of published work:
Investigation of the structure of the Standard Model effective potential at very large field strengths opens a window towards new phenomena and can reveal properties of the UV completion of the SM. The map of the lifetimes of the vacua of the SM...

We will present the recent progress on a model-independent estimate of the LHC potential to detect anomalous Higgs couplings in gluon-fusion double Higgs production. Our estimate of the sensitivity at 100 TeV collider will be presented as well if time is allowed.

We consider a scenario where supersymmetry is broken at a high energy scale, out
of reach of the LHC, but leaves a few fermionic states at the TeV scale. The particle
content of the low-energy effective theory is similar to that of Split Supersymmetry.
However, the gauginos and higgsinos are replaced by fermions carrying the same quantum numbers but having different couplings, which we call...

We construct a natural supersymmetry breaking model, with light third generation squarks and small radiative corrections to the Higgs up soft mass, by identifying flavour gauge messengers with magnetic quark superfields of $\mathcal{N}=1$ Supersymmetric QCD. Although these models of flavour and supersymmetry breaking are strongly coupled, through Seiberg duality we have a calculable and...

Axion, a very light pseudo-Goldstone boson is motivated by resolving the strong CP problem and has been a subject of phenomenological interest. For it to exist, we need a global symmetry, Peccei-Quinn symmetry. In this talk, we consider a case where this global symmetry is a remnant of an anomalous U(1) gauge symmetry and its breaking is related to the supersymmetry breaking. It explains...

"As it has been shown in the literature, triplet extended Higgs sectors suffer from fine tuning issues not present in the usual SM. These problems were solved in the Georgi-Macachek (GM) model by introducing a custodially invariant triplet extended Higgs sector. The quadratic divergences that arise in the corrections to the rho parameter in the GM model disappear when making it supersymmetric....

The Triplet extension of the MSSM (TMSSM) alleviates the little hierarchy problem and provides a significant enhancement of the loop-induced diphoton rate of the lightest CP-even Higgs h. In this paper we pursue the analysis of the TMSSM Higgs phenomenology by computing for the first time the h into Z + gamma decay. Interestingly we find that the rates of loop-induced decays are correlated and...

LHC8 raised doubts on using naturalness as a guide in our quest for physics beyond the Standard Model. In MSSM fine tuning enters through the Higgs mass and in non-minimal extensions through the negative superpartner searches. One non-minimal theory with a less severe missing superpartner problem, is MSSM with Dirac gauginos. Dirac gauginos are also known to lead to much milder flavour...

SuSy and other BSM phenomenology
Parallel Session talk
In this talk, I will briefly review the triplet extended MSSM, and then show that for a sizable portion of viable parameter space, associated with a large but still perturbative triplet coupling, the model features conspicuously smaller fine-tuning than in the case of MSSM-like couplings. I will then present the results of a fit to Higgs physics data as well as to low energy observables like...
