Realizing the supersymmetric inverse seesaw model in the framework of R-parity violation

If, on one hand, the inverse seesaw is the paradigm of TeV scale seesaw mechanism, on the other it is a challenge to find scenarios capable of realizing it. In this work we propose a scenario, based on the framework of R-parity violation, that realizes minimally the supersymmetric inverse seesaw mechanism. In it the energy scale parameters involved in the mechanism are recognized as the vacuum expectation values of the scalars that compose the singlet superfields $\hat N^C$ and $\hat S$. We develop also the scalar sector of the model and show that the Higgs mass receives a new tree-level contribution that, when combined with the standard contribution plus loop correction, is capable of attaining $125$GeV without resort to heavy stops.Comment: Minor modification of the text.

Energy dissipation and equivalent damping of RC columns subjected to biaxial bending: an investigation based in experimental results

The cyclic behaviour of reinforced concrete columns have been object of many experimental studies in the recent past years. However, the experimental studies on the biaxial response of RC columns are still limited. In this paper are presented the main results of an experimental study of 24 full-scale rectangular building columns tested for different loading paths under uniaxial and biaxial conditions. The experimental results are presented and discussed in terms of global behaviour, particularly focusing on the stiffness and strength degradation due to the increasing cyclic demand, and energy dissipation evolution. The equivalent viscous damping was estimated based on the experimental results of the RC columns tested under biaxial loading and empirical expressions are proposed
