Lo spettacolo della guerra. I «panorami» delle campagne rivoluzionarie e napoleoniche tra Inghilterra e Francia (1793-1816)
No full textIn 1787 Robert Barker, an Irish painter living in Edinburgh, patented the panorama, an immense circular painting which for the first time allowed viewers to immerse themselves in the canvas. Launched in London in 1791, the panorama rapidly spread throughout Europe, becoming particularly popular in Paris. The aim of this article is to reconstruct the genesis of the panorama industry in London and Paris between 1793 and 1816, a period in which war between France and England monopolized the market. More precisely, the article will investigate the reasons for the success of the military panorama, highlighting its decisive role in the transformation of public imaginary and the spectacularization of war
Immersive Risorgimento: The Panoramas of the Battle of Solferino in France and Italy
No full textThe years between the end of the 18th century and the beginning of the 19th century were marked by a great media transformation that led to a process of spectacularisation of politics. The war dimension was decisively affected by this transformation. A whole set of new cultural products offered to the public a virtual participation in war events of the time. Panoramas were the most effective ones, as they allowed for an immersive experience of the battlefields. At the same time, panoramas conquered the interest of institutions which integrated them into their policies of spectacularisation. The aim of this paper is to show how panoramas were crucial in the 19th-century process of militarisation of the imageries, by presenting the Italian unification, the so-called Risorgimento, as a case study. More precisely, the paper will focus on the panoramas devoted to the battle of Solferino (June 24, 1859), in which the Piedmontese and French armies defeated the Austrians. The Panorama of the Battle of Solferino, painted by Jean-Charles Langlois in 1865, and the similarly themed ones exhibited in Milan in 1881 and in Turin in 1884, will be discussed
Visitare il Risorgimento: turismo patriottico e diplomazia della memoria a Solferino e San Martino (1859-1909)
No full textIn the 19th century, battlefields played an increasingly important role in the imaginaries
and sensibilities of the public, establishing themselves as destinations of a new travel
experience that can be defined as patriotic tourism. The article will consider the Italian Risorgimento, presenting the battle of Solferino and San Martino as a case study. More precisely, it will reconstruct the touristic and memorial policies implemented
by the Society of Solferino and San Martino, from the aftermath of the battle until the
celebration of its fiftieth anniversary in 1909, under the different presidencies of Luigi
Torelli, Vincenzo Stefano Breda and Carlo Maluta. A transnational perspective will also
be adopted, analysing touristic flows from abroad and the central role played by French
diplomacy in publicising and promoting the sites of the 1859 Campaign
Dentro la «boutique» filellenica. I «panorami» della Guerra d'indipendenza greca (1821-1832)
No full textIn 1821, the outbreak of the Greek War of Independence sparked a philhellenic mobilization that drew in the European public with a never-before-seen intensity. The media, and military panoramas in particular, played a decisive role in this veritable «Graecomania». Patented in 1787, the panorama consisted in an immense circular canvas, allowing the spectator to be completely immersed in the painted subject. Having faced a crisis with the end of the Napoleonic wars, the military panorama received fresh impetus from the Hellenic conflict, and it became a huge success, especially in Paris and London. Filling a gap in the scientific literature, this article aims to reconstruct the story of the philhellenic panoramas produced in France and England with a transnational perspective, highlighting the innovative ways through which they mediatized and spectacularized the Greek War of Independence. More precisely, the philhellenic season launched two formats: the fixed panorama, perfected in France by Jean-Charles Langlois, and the moving panorama, popularized in England by a varied crowd of stage designers and entertainment entrepreneurs
Heavy-flavour production in Pb-Pb collisions at = 2.76 TeV with the ALICE detector
No full textHadrons containing heavy-flavours, i.e. charm and beauty quarks, are unique probes of the properties of the hot and dense QCD medium produced in heavy-ion collisions. Due to their large masses, heavy quarks are produced at the initial stage of the collision, almost exclusively via hard partonic scattering processes. Therefore, they are expected to experience the full collision history propagating through and interacting with the QCD medium. The parton energy loss, which is sensitive to the transport coefficients of the produced medium, can be studied experimentally by measuring the nuclear modication factor () which accounts for the modication of the heavy-flavoured hadron yield in Pb-Pb collisions with respect to pp collisions. In semi-central Pb-Pb collisions, the degree of thermalization of charm quarks in the QCD medium can be accessed via the measurement of the heavy flavour elliptic flow at low . At high , is sensitive to the path-length dependence of heavy quark in-medium energy loss. The ALICE collaboration has measured the production of open heavy flavour hadrons via their hadronic and semi-leptonic decays at mid-rapidity and in the semi-muonic decay channel at forward rapidity in pp, p-Pb and Pb-Pb collisions at 7, 5.02 and 2.76 TeV respectively. In this talk the current results on open heavy-flavour and will be presented.Hadrons containing heavy-flavours, i.e. charm and beauty quarks, are unique probes of the properties of the hot and dense QCD medium produced in heavy-ion collisions.

Experimental overview on heavy-flavor production
No full textHadrons containing heavy-flavors are unique probes of the properties of the hot and dense QCD medium produced in heavy-ion collisions. Due to their large masses, heavy quarks are produced at the initial stage of the collision, almost exclusively via hard partonic scattering processes. Therefore, they are expected to experience the full collision history propagating through and interacting with the QCD medium. The parton energy loss, which is sensitive to the transport coefficients of the produced medium, can be studied experimentally by measuring the nuclear modification factor which accounts for the modification of the heavy-flavored hadron yield in Pb-Pb collisions with respect to pp collisions. In semi-central Pb-Pb collisions, the degree of thermalization of charm quarks in the QCD medium can be accessed via the measurement of the heavy flavor elliptic flow v2 at low pT. Furthermore, the measurement of heavy-flavors production in pp collisions allows testing the perturbative QCD calculations. The PHENIX and STAR Collaborations at the Relativistic Heavy-Ion Collider and ALICE, CMS and ATLAS Collaborations at the Large Hadron Collider have measured the production of charmonium and bottonium states as well as open heavy flavor hadrons via their hadronic and semi-leptonic decays at mid-rapidity and in the semi-muonic decay channel at forward rapidity in pp, p-A and A-A collisions in an energy domain that ranges from = 0.2 TeV to = 13 TeV in pp collisions and from = 0.2 TeV to = 5.02 TeV in A-A collisions. In this contribution the latest experimental results will be reviewed
Anisotropic Flow in the Few Collisions Regime: Application to Bottomonia

Hot Quarks 2018 — Workshop for Young Scientists on the Physics of Ultrarelativistic Nucleus-Nucleus Collisions. Proceedings. Vol 10. Basel Switzerland: MDPI; 2019: 16.Considering the kinetic Boltzmann equation in the limit of very few collisions, we study the evolution of the phase space distribution of bottomonia interacting with an expanding gas of massless partons. We investigate the scaling of the anisotropic flow coefficients on the initial eccentricities and the inverse Knudsen number, and compute their transverse momentum dependence
Open charm via D mesons using the ALICE detector at CERN-LHC
No full textCharm and bottom quarks have been proposed as probes to study hot quark matter produced in high-energy heavy-ion collisions. The detailed understanding of the charm cross-section in proton-proton collisions as well as the production mechanisms is of considerable interest as QCD test tool and as reference calibration for heavy-ion studies. Measurements of D mesons yield in minimum bias proton-proton collisions can be used to extract the charm cross-section. In this contribution we present latest results on performance studies of the reconstruction of D0, D* and D+ mesons in proton-proton collisions at √s = 7 TeV using the ALICE central detector. The D0 meson is reconstructed through the hadronic channel D0 → K-π+ while the D* meson is reconstructed through the hadronic decay sequence D*+ → D0π+ and D0 → K-π+ (and their charge conjugate channels). The D+ is reconstructed through the channel D+ → K-π+ π+ . A preliminary discussion on possible sources of systematic is done
