The Theories of Interconstitutionality and Transconstitutionalism. Preliminary Insights from a Jus-cultural Perspective (With a view to Transnational Social Justice)

In the following pages, some light will hopefully be shed into the recent proposals of interconstitutionality and transconstitutionalism – deemed highly influential among Portuguese and Spanish-speaking countries – considering them against the backdrop defined by the more general disquisitions recently devoted to interculturality and transculturality in their quality of practical responses to the globalization and social differentiation phenomena. Acknowledging the fact that, even inside the juridical linguistic game and within the juristic community of interpreters, the new narratives interwoven through the above mentioned concepts are becoming more and more intricate – v.g., including epistemic and normative, as well as subjective and objective perspectives, giving birth to new elaborate semantic networks and covering an ever growing territory – it is important to admonish, at the outset, that, in this stance, we cannot but provide a preliminary and provisory map of the vast continent thereby comprised. As a consequence, the present text will limit itself to the signalling of some landmarks and the rough drawing of the basic lineaments for further (and certainly wiser and more competent) cartographic and exploratory endeavours

Dirac and Majorana heavy neutrinos at LEP II

The possibility of detecting single heavy Dirac and Majorana neutrinos at LEP II is investigated for heavy neutrino masses in the range $M_N=(\sqrt s/2, \sqrt s)$. We study the process $e^+e^- \longrightarrow \nu_{\ell} \ell q_i \bar q_j$ as a clear signature for heavy neutrinos. Numerical estimates for cross sections and distributions for the signal and the background are calculated and a Monte Carlo reconstruction of final state particles after hadronization is presented.Comment: 4 pages, 8 figure

Discriminating among the theoretical origins of new heavy Majorana neutrinos at the CERN LHC

A study on the possibility of distinguishing new heavy Majorana neutrino models at LHC energies is presented. The experimental confirmation of standard neutrinos with non-zero mass and the theoretical possibility of lepton number violation find a natural explanation when new heavy Majorana neutrinos exist. These new neutrinos appear in models with new right-handed singlets, in new doublets of some grand unified theories and left-right symmetrical models. It is expected that signals of new particles can be found at the CERN high-energy hadron collider (LHC). We present signatures and distributions that can indicate the theoretical origin of these new particles. The single and pair production of heavy Majorana neutrinos are calculated and the model dependence is discussed. Same-sign dileptons in the final state provide a clear signal for the Majorana nature of heavy neutrinos, since there is lepton number violation. Mass bounds on heavy Majorana neutrinos allowing model discrimination are estimated for three different LHC luminosities.Comment: 7 pages, 5 figure
