Reflexiones periféricas sobre las disyuntivas identitarias de una Europa en crisis: oscilaciones de un sueño paneuropeo cargado de una compleja vanidad
La Europa moderna, se ha erigido
como centro irradiador de cultura y valores
universales, en representación de
la civilización occidental. Los enfoques
eurocéntricos han generado el diseño
hegemónico de construcciones sociales
que han permitido construir una idea de
pertenencia a pesar de la falta de unidad
al interior de un continente profundamente
diverso, en donde múltiples identidades
-locales, nacionales y regionales
- entran sistemáticamente en fricción.
Así, mientras, por un lado, el viejo continente
se halla atravesando un proceso
transitivo producto de una nueva crisis
multidimensional, por otro, aún puede
apreciarse una cuota de vanidad en ciertos
sectores -cuya versión extrema aquí
se ha denominado Euronarcisimo- respecto
del rol civilizatorio que aquel debe
desempeñar en el actual sistema global.
En ese marco, el presente artículo surgido
de las experticias vividas en el viejo continente
por estos autores, analiza la actual
coyuntura europea, rescatando algunas
de las principales contradicciones identitarias
que emergen y se profundizan
mientras Europa piensa su nuevo rol en
un mundo en cambioModern Europe has emerged as a radiating
center of culture and universal
values, representing Western civilization.
Eurocentric approaches have generated
the design of hegemonic social constructs
that have allowed it to build a sense
of belonging despite the lack of unity
within a deeply diverse continent, where
multiple local, regional and national
identities, are in friction systematically.
So, on the one hand, the old continent is
undergoing a transitive process product
of a new multidimensional crisis, on the
other, can still be seen a vanity in certain
sectors - extreme version of which has
been termed here Euronarcisimo - about
civilization role that it be should play in
the current global system. In this context,
this paper that emerged from the expertise
gained in the old continent by these
authors, analyzes the current European
situation, some of major identity contradictions
that emerge and deepened as
Europe rethinks his new role on a changing

Non-standard neutrino interactions in IceCube
Non-standard neutrino interactions (NSI) may arise in various types of new physics. Their existence would change the potential that atmospheric neutrinos encounter when traversing Earth matter and hence alter their oscillation behavior. This imprint on coherent neutrino forward scattering can be probed using high-statistics neutrino experiments such as IceCube and its low-energy extension, DeepCore. Both provide extensive data samples that include all neutrino flavors, with oscillation baselines between tens of kilometers and the diameter of the Earth.
DeepCore event energies reach from a few GeV up to the order of 100 GeV - which marks the lower threshold for higher energy IceCube atmospheric samples, ranging up to 10 TeV.
In DeepCore data, the large sample size and energy range allow us to consider not only flavor-violating and flavor-nonuniversal NSI in the μ−τ sector, but also those involving electron flavor.
The effective parameterization used in our analyses is independent of the underlying model and the new physics mass scale. In this way, competitive limits on several NSI parameters have been set in the past. The 8 years of data available now result in significantly improved sensitivities. This improvement stems not only from the increase in statistics but also from substantial improvement in the treatment of systematic uncertainties, background rejection and event reconstruction
IceCube Search for Earth-traversing ultra-high energy Neutrinos
The search for ultra-high energy neutrinos is more than half a century old. While the hunt for these neutrinos has led to major leaps in neutrino physics, including the detection of astrophysical neutrinos, neutrinos at the EeV energy scale remain undetected. Proposed strategies for the future have mostly been focused on direct detection of the first neutrino interaction, or the decay shower of the resulting charged particle. Here we present an analysis that uses, for the first time, an indirect detection strategy for EeV neutrinos. We focus on tau neutrinos that have traversed Earth, and show that they reach the IceCube detector, unabsorbed, at energies greater than 100 TeV for most trajectories. This opens up the search for ultra-high energy neutrinos to the entire sky. We use ten years of IceCube data to perform an analysis that looks for secondary neutrinos in the northern sky, and highlight the promise such a strategy can have in the next generation of experiments when combined with direct detection techniques
Posteriori analysis on IceCube double pulse tau neutrino candidates
The IceCube Neutrino Observatory at the South Pole detects Cherenkov light emitted by charged secondary particles created by primary neutrino interactions. Double pulse waveforms can arise from charged current interactions of astrophysical tau neutrinos with nucleons in the ice and the subsequent decay of tau leptons. The previous 8-year tau double pulse analysis found three tau neutrino candidate events. Among them, the most promising one observed in 2014 is located very near the dust layer in the middle of the detector. A posterior analysis on this event will be presented in this paper, using a new ice model treatment with continuously varying nuisance parameters to do the targeted Monte Carlo re-simulation for tau and other background neutrino ensembles. The impact of different ice models on the expected signal and background statistics will also be discussed
