Search for massive rare particles with MACRO
Massive rare particles have been searched for in the penetrating cosmic
radiation using the MACRO apparatus at the Gran Sasso National Laboratories.
Liquid scintillators, streamer tubes and nuclear track detectors have been used
to search for magnetic monopoles (MMs).
Based on no observation of such signals, stringent flux limits are
established for MMs as slow as a few 10^(-5)c. The methods based on the
scintillator and on the nuclear track subdetectors were also applied to search
for nuclearites. Preliminary results of the searches for charged Q-balls are
also presented.Comment: 20 pages, 9 EPS figures included with epsfi
Supplement: "Localization and broadband follow-up of the gravitational-wave transient GW150914" (2016, ApJL, 826, L13)
This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands
Matter effects in upward-going muons and sterile neutrino oscillations
The angular distribution of upward-going muons produced by atmospheric neutrinos in the rock below the MACRO detector shows anomalies in good agreement with two flavor nu (mu) --> nu (tau) oscillations with maximum mixing and Deltam(2) around 0.0024 eV(2). Exploiting the dependence of magnitude of the matter effect on oscillation channel, and using a set of 809 upward-going muons observed in MACRO, we show that the two flavor nu (mu) --> nu (s) oscillation is disfavored with 99% C.L. with respect to nu (mu) --> nu (tau).

Search for lightly ionizing particles with the MACRO detector
A search for lightly ionizing particles has been performed with the MACRO detector. This search was sensitive to particles with charges between 1/5e and close to the charge of an electron, with beta between approximately 0.25 acid 1.0. Unlike previous searches both single track events and tracks buried within high multiplicity muon showers were examined. In a period of approximately one year no candidates were observed. Assuming an isotropic flux, for the single track sample this corresponds to a 90%, C.L. upper flux limit Phi less than or equal to 9.2 x 10(-15) cm(-2) s(-1) sr(-1)
Realismo e utopia: da More a Eberlin
With his Statuten aus dem Land Wolfaria (1521), Johann Eberlin von Günzburg is the first author to imitate More’s Utopia, even though Eberlin’s proposals for religious, social and political reform are addressed directly at contemporary Germany, in the style of the pamphlets that characterize the first years of the Reformation. Often acknowledged as the first Lutheran utopia, Wolfaria has in fact little in common with the subtle Humanistic game played by Erasmus and More, yet it still is an extremely interesting work, precisely because it allows us to perceive, in all their unresolved issues, the enthusiastic moments of fervent Lutheran propaganda of the beginning
Le De regia sapientia de Botero et De la naissance, durée et chute des Estats de Lucinge
Dans le cadre d’une recherche plus vaste sur les origines françaises du débat italien sur la raison d’État à la fin du XVIe siècle, Enzo Baldini étudie les liens étroits des deux livres de Giovanni Botero et de René de Lucinge. L’auteur montre comment le dialogue que les deux hommes entretinrent durant les années 1580 fut décisif non seulement pour le traité que Lucinge consacra à la Naissance, durée et chute des Estats, mais aussi pour la réflexion de Botero sur la « raison par laquelle on gouverne un État »
