Search for high-mass resonances decaying to dimuons at CDF.
2009
We present a search for high-mass neutral resonances using dimuon data corresponding to an integrated luminosity of 2.3 fb(-1) collected in pp collisions at s=1.96 TeV by the CDF II detector at the Fermilab Tevatron. No significant excess above the standard model expectation is observed in the dimuon invariant-mass spectrum. We set 95% confidence level upper limits on sigma BR(pp -> X ->mu mu), where X is a boson with spin-0, 1, or 2. Using these cross section limits, we determine lower mass limits on sneutrinos in R-parity-violating supersymmetric models, Z(') bosons, and Kaluza-Klein gravitons in the Randall-Sundrum model.
Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider
2020
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these longlived particles (LLPs) can decay far from the interaction vertex of the primary proton–proton collision. Such LLP signatures are distinct from those of promptly decaying particles that are targeted by the majority of searches for new physics at the LHC, often requiring customized techniques to identify, for example, significantly displaced decay vertices, tracks with atypical properties, and short track segments. Given their non-standard nature, a comprehensive overview of LLP…
Épigraphie religieuse et communautés civiques au Haut-Empire : la délimitation du territoire de la ciuitas Aeduorum aux IIe et IIIe siècles
2013
Since the 19th century, many proposals have been made regarding the boundaries of the territory of the civitas Aeduorum. Although there is general agreement on many geographic sectors, there are still major discrepancies of opinion, principally in the regions of Autissiodurum / Auxerre and Alesia. The religious epigraphy of the Early Empire, in particular the use of a specific formulary, seems to demonstrate a single religious (and political) community in these regions, which would thus have all belonged to the civitas Aeduorum in the 2nd and 3rd centuries.
Il cuore e la ragione secondo Pascal
2018
Il saggio riflette sulla dottrina pascaliana del cuore, centro della fede e del pensiero.
Il cuore e la critica della ragione. Ripartire da Laporte
2018
The author presents the Italian translation of the text by Jean Laporte "Le coeur et la raison selon Pascal", identifying in the hearth a critic instance of reason. This reflection is conducted through the reference to the work of Jean Luc Marion in his essay on Negative Certainties.
Implications for dark matter direct detection in the presence of LIGO-motivated primordial black holes
2019
We discuss formation of dark matter (DM) mini-halos around primordial black holes (PBHs) and its implication on DM direct detection experiments, including axion searches. Motivated by LIGO observations, we consider $f_{\textrm{DM}} \simeq 0.01$ as the fraction of DM in PBHs with masses $10 M_{\odot} - 70 M_{\odot}$. In this case, we expect the presence of dressed PBHs after Milky Way halo formation with mini-halo masses peaked around $M_{\textrm{halo}} \sim (50-55) M_{\textrm{PBH}}$. We analyze the effect of tidal forces acting on dressed PBHs within the Milky Way galaxy. In the solar neighborhood, the mini-halos are resistant against tidal disruption from the mean-field potential of the ga…
Constraints on Cosmic Strings Using Data from the Third Advanced LIGO–Virgo Observing Run
2021
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 data set. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks and, for the first time, kink-kink collisions.cA template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension, $G\mu$, as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models.cAdditionally, we develop and test a third model which interpolat…
Molte Palermo. Temi
2019
Nel tema delle incompiute idee di città possibili si riconoscerà il paradigma connotativo dello stesso divenire di Palermo, lungo un percorso millenario di processi di trasformazione nessuno dei quali portato a compimento, in virtù di quel valore distintivo di exemplum che non necessita di ulteriori e conclusive dimostrazioni. Il corso della storia, del resto, ha imposto a Palermo il ciclico riproporsi di destini interrotti. Tale si rilevò l’invenzione della città capitale, quella della “quadratura geometrica e della croce di strade” sovrimpressa a quella archetipica e fondativa della Pan-ormos scambiatrice. E l’incompiutezza sarà il tratto distintivo della città dei rettifili stradali otto…

The Antinomy of Hospitality and The Double Imperative
2017
The purpose of this paper is to develop, on the basis of the comparison that Derrida engages with Kant on hospitality, some remarks on Kant’s concept of reason, and to show how the “right to visit”, in which space Kant de nes cosmopolitan right, implies a radical openness to the needs of the other, which Kant places at the heart of the concept of reason and which decides, therefore, the way each of us, as a man, can be said to be rational. Rationality and hospitality are placed on the same edge in the re ection of J. Derrida, who radicalizes the link between responsibility and practical reason and transforms the Kantian ‘Du sollst, also kannst du auch’ into an aporia, a term that does not i…
