Territory and memory: The Landing of the Allies in Sicily in 1943

The concept of memory (memorial site) has gained crucial importance in recent years for the identification of places (areas) and in the affirmation of local identities. The memorial sites are areas where usually tragic events have occurred and resulted in a cultural change. In these places there are still signs of these historical events and/or tangible and intangible indications created by the society such as: monuments, obelisks, marble inscriptions, others. Sicily represents an ideal area for studying memorial sites; not only because of the number of dominations in the past centuries, but also for the significance of all places where the mafia has taken its root. These elements have caused several changes in the culture and in the landscape. Sicily is the land where \u201cOperation Husky\u201d began, in the summer of 1943. This agreement between the Americans and the British aimed at occupying Sicily, Italy after World War II. Seventy years after this operation the territory is still marked by testimonies of those tragic events. The bombing devastated buildings, which we can still acknowledge for their cultural significance. These memorial areas represent a strong testimony of the past. There are cemeteries, protecting bodies many of which are unknown; there are bunkers and other military garrisons well preserved throughout the territory. These signs must be rediscovered, to be replicated because of the contemporary geopolitical situation. As a result, in this paper we propose to identify the area of eastern Sicily suitable for a tourist itinerary in the cultural memory of the war of 1943. The idea is to encourage tourism that gives rise to real emotions and thoughts

Positrons in Cosmic Rays from Dark Matter Annihilations for Uplifted Higgs Regions in MSSM

We point out that there are regions in the MSSM parameter space which successfully provide a dark matter (DM) annihilation explanation for observed positron excess (e.g. PAMELA), while still remaining in agreement with all other data sets. Such regions (e.g. the uplifted Higgs region) can realize an enhanced neutralino DM annihilation dominantly into leptons via a Breit-Wigner resonance through the CP-odd Higgs channel. Such regions can give the proper thermal relic DM abundance, and the DM annihilation products are compatible with current antiproton and gamma ray observations. This scenario can succeed without introducing any additional degrees of freedom beyond those already in the MSSM.Comment: 11 pages, 9 figure

High energy gamma-ray constraints on decaying Dark Matter

New bounds on decaying Dark Matter are derived from the gamma-ray measurements of (i) the isotropic residual (extragalactic) background by Fermi and (ii) the Fornax galaxy cluster by H.E.S.S. We find that those from (i) are among the most stringent constraints currently available, for a large range of dark matter masses and a variety of decay modes, excluding half-lives up to about 10^26 to few 10^27 seconds. In particular, they rule out the interpretation in terms of decaying dark matter of the e+/- spectral features in PAMELA, Fermi and H.E.S.S., unless very conservative choices are adopted. We also discuss future prospects for CTA bounds from Fornax which, contrary to the present H.E.S.S. constraints of (ii), may allow for an interesting improvement and may become better than those from the current or future extragalactic Fermi data.Comment: In Proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), ID622, Rio de Janeiro (Brazil
