Uccisioni mirate, legittima difesa preventiva e diritti umani

2018

Targeted killings by drones on the territory of other States has increasingly become the US Administration’s weapon of choice in the war against terrorism. According to the US, these operations constitute a justified use of self-defensive force «against terrorists who pose a continuing and imminent threat to the American people» (Remarks by the President at the National Defense University, 23 May 2013, www.whitehouse.gov). The aim of the present article is to assess the validity of this justification under both ius ad bellum and international human rights law. To this end, Section 1 introduces the arguments advanced by the US Administration. Section 2 explores the admissibility of anticipat…

Omicidi mirati a mezzo drone: brevi riflessioni a margine del caso "Lo Porto" tra diritto penale e diritto internazionale

2018

Quale diritto penale in ipotesi di "vittime collaterali" di drone strike? La sempre maggiore rilevanza che il fenomeno degli omicidi mirati a mezzo drone assume nel contesto internazionale pone la necessità di interrogarsi su come, nell'ordinamento interno, le categorie classiche del diritto penale debbano operare rispetto a fattispecie "peculiari", caratterizzate da una distanza fisica e psichica dal target e dall’esistenza di una “catena di comando” coinvolta, a più livelli, nella singola operazione di omicidio mirato. Si cercherà pertanto di capire, partendo dal caso dell'omicidio di un cittadino italiano per mezzo di droni statunitensi in Pakistan, ma fornendo un contributo di portata p…

Searching for signatures around 1920 MeV of a N-* state of three hadron nature

2009

We provide a series of arguments which support the idea that the peak seen in the gamma p -> K+ Lambda reaction around 1920 MeV should correspond to the recently predicted state of J(P) = 1/2(+) as a bound state of K(K) over bar N with a mixture of alpha(0)(980)N and f(0)(980)N components. At the same time we propose polarization experiments in that reaction as a further test of the prediction, as well as a study of the total cross-section for gamma p -> K(+)K(-)p at energies close to threshold and of d sigma/dM(inv) for invariant masses close to the two-kaon threshold.

Conceptual design and simulation of a water Cherenkov muon veto for the XENON1T experiment

2014

XENON is a direct detection dark matter project, consisting of a time projection chamber (TPC) that uses xenon in double phase as a sensitive detection medium. XENON100, located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, is one of the most sensitive experiments of its field. During the operation of XENON100, the design and construction of the next generation detector (of ton-scale mass) of the XENON project, XENON1T, is taking place. XENON1T is being installed at LNGS as well. It has the goal to reduce the background by two orders of magnitude compared to XENON100, aiming at a sensitivity of $2 \cdot 10^{-47} \mathrm{cm}^{\mathrm{2}}$ for a WIMP mass of 50 GeV/c$^{2}$.

Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at E beam =4 TeV

2018

Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation this background arises mainly from scattering of the 4 TeV protons on residual gas in the beam pipe. Methods of reconstructing the BIB signals in the ATLAS detector, developed and implemented in the simulation chain based on the FLUKA Monte Carlo simulation package, are described. The interaction rates are determined from the residual gas pressure distribution in the LHC ring in order to set an absolute scale on the predicted rates of BIB so that they can be compared qua…
