A top-quark mass measurement feasibility study in the tt ̄ dilepton channel at LHC and at future hadronic colliders
No full textThis contribution documents the first efforts being taken to study the feasibility of a measurement of the top-quark mass at the Large Hadron Collider and future hadron colliders in pair production events in the dilepton channel

New Physics signals from measurable polarization asymmetries at LHC
No full textWe propose a new type of Z polarization asymmetry in bottom-Z production at LHC that should be realistically measurable and would provide the determination of the so-called Ab parameter, whose available measured value still appears to be in disagreement with the Standard Model prediction; we discuss the overall expected precision of this measurement and its implications. If Supersymmetry is found, a second polarization, i.e. the top longitudinal polarization in top-charged Higgs production, would neatly identify the tan β parameter. In this case, the value of Ab should be in agreement with the Standard Model. If Supersymmetry does not exist, a residual disagreement of AbAb from the Standard Model prediction would be a clean signal of New Physics of “non-Supersymmetric” origin
Testing Bell Inequalities at the LHC with Top-Quark Pairs
No full textCorrelations between the spins of top-quark pairs produced at a collider can be used to probe quantum entanglement at energies never explored so far. We show how the measurement of a single observable can provide a test of the violation of a Bell inequality at the 98% C.L. with the statistical uncertainty of the data already collected at the Large Hadron Collider, and at the 99.99% C.L. with the higher luminosity of the next run. Detector acceptance, efficiency, and migration effects are taken into account. The test relies on the spin correlations alone and does not require the determination of probabilities-in contrast to all other tests of Bell inequalities

EOF analysis of complex response of Venice mobile gates
No full textThe complex dynamics of the Venice tidal barrier subjected to broadbanded wave spectra are investigated by applying empirical orthogonal function (EOF) analysis to experimental data sets. Space and frequency patterns of the natural modes of the barrier are reconstructed and satisfactorily compared with the recent theory of Li and Mei. The results indicate that when broadbanded wave spectra are considered, natural modes with the longest spatial wavelengths seem more likely to be excited than those with shorter wavelengths
