Heavy ions at the Future Circular Collider
2016
The Future Circular Collider (FCC) Study is aimed at assessing the physics potential and the technical feasibility of a new collider with centre-of-mass energies, in the hadron-hadron collision mode, seven times larger than the nominal LHC energies. Operating such machine with heavy ions is an option that is being considered in the accelerator design studies. It would provide, for example, Pb-Pb and p-Pb collisions at sqrt{s_NN} = 39 and 63 TeV, respectively, per nucleon-nucleon collision, with integrated luminosities above 30 nb^-1 per month for Pb-Pb. This is a report by the working group on heavy-ion physics of the FCC Study. First ideas on the physics opportunities with heavy ions at th…
Działalność animacyjna liderów Lokalnej Grupy Działania w środowisku wiejskim (przykład Śląska Opolskiego)
2016
Artykuł omawia modernizację obszarów wiejskich Śląska Opolskiego w perspektywie działań animacyjnych podejmowanych przez liderów lokalnych skupionych w Lokalnej Grupie Działania. Przeanalizowano – na podstawie badań terenowych – ich współpracę z Fundacją Euro-Country – partnerstwo dla zrównoważonego rozwoju obszarów wiejskich, która wspólnie z nimi wdraża lokalną strategię rozwoju, budując lokalne partnerstwo i integrując społeczności wiejskie wokół idei zrównoważonego i wielofunkcyjnego rozwoju.
First measurement of quarkonium polarization in nuclear collisions at the LHC
2021
The polarization of inclusive J/$\psi$ and $\Upsilon(1{\rm S})$ produced in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region $2.5<y<4$ and measuring the polar and azimuthal angular distributions of the muons. The polarization parameters $\lambda_{\theta}$, $\lambda_{\phi}$ and $\lambda_{\theta\phi}$ are measured in the helicity and Collins-Soper reference frames, in the transverse momentum interval $2<p_{\rm T}<10$ GeV/$c$ and $p_{\rm T}<15$ GeV/$c$ for the J/$\psi$ and $\Upsilon(1{\rm S})$, respectively. The polarization parameter…
Multipion Bose-Einstein correlations in pp,p-Pb, and Pb-Pb collisions at energies available at the CERN Large Hadron Collider
2016
Three- and four-pion Bose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC. We compare our measured four-pion correlations to the expectation derived from two- and three-pion measurements. Such a comparison provides a method to search for coherent pion emission. We also present mixed-charge correlations in order to demonstrate the effectiveness of several analysis procedures such as Coulomb corrections. Same-charge four-pion correlations in pp and p-Pb appear consistent with the expectations from three-pion measurements. However, the presence of non-negligible background correlations in both systems prevent a conclusive statement. In Pb-Pb collisions, we obse…
Performance of the ALICE experiment at the CERN LHC
2014
ALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe the running environment and the data handling procedures, and discuss the performance of the ALICE detectors and analysis methods for various physics observables.
Beyond the standard model via extended symmetries and dark matter
2015
In this thesis, we discuss ideas of how to go beyond the Standard Model (SM) of particle physics to incorporate the cosmological observations of dark matter and matter–antimatter asymmetry, and to address the theoretical problems related to the scalar sector of the SM. Although the SM has proven to be an excellent description of the interactions of elementary particles, there is both experimental and theoretical evidence that this description cannot be complete. Most notably, the cosmological observations of dark matter (DM) and the matter–antimatter asymmetry in the universe cannot be explained within the SM. We have studied simple singlet extensions of the SM. We found out that these DM a…
Review of proton and nuclear shape fluctuations at high energy
2020
Determining the inner structure of protons and nuclei in terms of their fundamental constituents has been one of the main tasks of high energy nuclear and particle physics experiments. This quest started as a mapping of the (average) parton densities as a function of longitudinal momentum fraction and resolution scale. Recently, the field has progressed to more differential imaging, where one important development is the description of the event-by-event quantum fluctuations in the wave function of the colliding hadron. In this Review, recent developments on the extraction of proton and nuclear transverse geometry with event-by-event fluctuations from collider experiments at high energy is …
Proton shape fluctuation and its relation to DIS
2018
We review the recent progress in extracting the proton fluctuating substructure by studying exclusive processes at HERA, and the applications of these developments in the interpretation of the LHC heavy ion data. The possibilities to extract the proton geometry directly from the LHC high-multiplicity proton-nucleus and proton-proton collision data is also discussed. peerReviewed
Development of competencies by PBL and evaluation with rubrics in the group work in Higher Education
2019
[ES] La investigación acerca del desarrollo de competencias con ABP ha crecido mucho en los últimos años, sin embargo, no se han investigado sus consecuencias sobre procesos psicosociales, como la creatividad, liderazgo entre iguales y cohesión de equipo en el trabajo en grupo. En este trabajo además se analizan las diferencias en el nivel competencial de 16 grupos de 4 estudiantes de la asignatura Psicología Social del Deporte del Grado en Ciencias de la Actividad Física y el Deporte como resultado de su participación en una metodología de ABP evaluada con rúbricas. Los instrumentos utilizados en esta experiencia se dividen en dos: la evaluación de competencias y la evaluación de variables…
El efecto del liderazgo auténtico y el tipo de establecimiento de metas sobre el desempeño y las respuestas actitudinales y afectivas de los seguidor…
2014
El papel que, en los últimos años, han jugado los líderes de organizaciones, tanto públicas como privadas, en el creciente número de escándalos que han sacudido la opinión pública internacional ha evidenciado la necesidad de un nuevo enfoque en el proceso de liderazgo. En este contexto, el liderazgo auténtico emerge como una alternativa post-heroica y post-autoritaria a los modelos de liderazgo basados en el carisma A pesar de que la investigación en liderazgo auténtico crece diariamente, aún es necesario explorar qué factores contextuales afectan a la influencia del líder auténtico sobre sus seguidores. En este contexto, el objetivo general de esta tesis es contribuir a la investigación so…
