Equality, Equity, and Diversity: Educational Solutions in the Basque Country
Public education is one of the greatest achievements of European countries during the twentieth century. While schooling systems neither exclusively form citizens, nor are they sufficient to alleviate all inequalities, education plays an increasingly important strategic role in relieving social problems and promoting the civic and ethical upbringing of our children. Researchers and professors at the UPV/EHU have had the privilege to design and implement important educational projects in conjunction with government of Autonomous Community of the Basque Country, which has the authority over education in its territory. This book presents the timely (in most cases since 2000) observations, research, and programs that have resulted from this cooperation. Our stress—in both our theoretical and analytical dimensions—has been on the importance of diversity, the promotion of social and human values, and respect for basic human rights. In addition, we describe the cooperation that must be fostered—and the various needs met—between all educational "agents": academic researchers, administrators, teachers, parents, and the community at large to promote equality and fairness in our society.This book was published with generous financial support from the Basque Government.Introduction: Alfonso Unceta and Concepción Medrano ?

Fine structure in the azimuthal transverse momentum correlations at GeV using the event shape analysis
The experimental results on transverse momentum azimuthal hadron correlations
at RHIC have opened a rich field for parton energy loss analysis in heavy-ion
collisions. Recently, a considerable amount of work has beendevoted to study
the shapes of the ``away-side'' jet which exhibit an interesting and unexpected
``double hump'' structure not observed in the analogous treatment of data.
Driven by the possibility that the latter result might just mean that such
structure exists already in the case of collisions, but that its relative
intensity could be small, here we use the Event Shape Analysis to show that it
is possible to identify and select well defined event topologies in
collisions, among which, a double hump structure for the away-side jet emerges.
Using two shape parameters, the sphericity in the transverse plane and the
recoil to analyze a sample of PYTHIA generated collisions at
GeV, we show that this structure corresponds to two jets
emitted in the backward hemisphere. Finally, we show that Q-PYTHIA
qualitatively reproduces the decrease in the yield of dijet events and the
increase of the double hump structure in the away side observed in heavy ion
collisions. The implications for the treatment of parton energy loss in
heavy-ion collisions are discussedComment: 6 pages, 7 fugures: One figure was changed, references were added.

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV
The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8 TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
