S=−1meson-baryon unitarized coupled channel chiral perturbation theory and theS01resonances Λ(1405) and -Λ(1670)
2003
The $s-$wave meson-baryon scattering is analyzed for the strangeness $S=-1$ and isospin I=0 sector in a Bethe-Salpeter coupled channel formalism incorporating Chiral Symmetry. Four channels have been considered: $\pi \Sigma$, $\bar K N$, $\eta \Lambda$ and $K \Xi$. The required input to solve the Bethe-Salpeter equation is taken from lowest order Chiral Perturbation Theory in a relativistic formalism. There appear undetermined low energy constants, as a consequence of the renormalization of the amplitudes, which are obtained from fits to the $\pi\Sigma\to\pi\Sigma$ mass-spectrum, to the elastic $\bar K N \to \bar K N$ and $ \bar K N\to \pi \Sigma$ $t$--matrices and to the $ K^- p \to \eta \…
Genealogie dell'empatia. Brecht, Lessing e Stanislavskij
2018
Sulla base di concetti quali empatia, compassione e immedesimazione, il lavoro mette a confronto le teorie estetiche di Brecht, Lessing e Stanislavskij. Ricostruendo le tappe del fecondo rapporto di scambio dialettico che lega il drammaturgo tedesco del '900 all'attore e regista russo e al drammaturgo teorico della drammaturgia della compassione del 700, si analizza un caso di tormentata ricezione. Based on concepts such as empathy, compassion and identification, the work compares the aesthetic theories of Brecht, Lessing and Stanislavsky.
Integrarsi nel Regno: da stranieri a cittadini in Sicilia tra attività mercantile, negozio politico e titolo di nobiltà
2014
Il saggio intende evidenziare in una prospettiva di lungo periodo i caratteri dell’integrazione dei numerosi mercanti stranieri presenti nel Regno di Sicilia, focalizzando alcune condizioni che la resero possibile sul piano politico e sociale. Nelle maggiori città erano presenti colonie di mercanti che vi dimoravano stabilmente «cum domo et familia», e diversi, grazie al matrimonio con donne del luogo poterono conseguirne la cittadinanza con i relativi privilegi connessi, riuscendo in molti casi a inserirsi tra le file dell’oligarchia urbana e occupando importanti cariche municipali. Da lì il passo verso l’acquisizione di un feudo e di un titolo nobiliare fu piuttosto breve, soprattutto in …

In this article, Segreto deals with the connection between the Other and the Power, moving from the topos of the Stranger in the Ancient Greek to ourdays Migrants.

The $K^+K^-$ invariant-mass interval ($M_{K^+K^-}$), number of selected events ($N_{\rm sig}$) after background subtraction, detection efficiency ($\varepsilon$), ISR luminosity ($L$), measured $e^+e^-\to K^+K^-$ cross section ($\sigma_{K^+K^-}$), and the charged-kaon form factor ($|F_K|$). For the number of events and cross section. For the form factor, we quote the combined uncertainty. For the mass interval 7.5 - 8.0 GeV/$c^2$, the 90$\%$ CL upper limits for the cross section and form factor are listed.

Measured amplitude and phase values for the $I=1/2$ $K \pi$ $\mathcal{S}$-wave as functions of mass obtained from the Model Independent Partial Wave Analysis (MIPWA) of $\eta_c \to K^0_{\scriptscriptstyle S} K^{\pm}\pi^{\mp}$. The amplitudes and phases in the mass interval 14 are fixed to constant values.
