H-3(Lambda) and (3)((Lambda)over-bar)(H)over-bar lifetime measurement in Pb-Pb collisions at √sNN=5.02 TeV via two-body decay
(2019) [Journal article]An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb–Pb collisions at √sNN =5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been ... -
Habilidad en preguntas conceptuales y en resolución de problemas de física
(1992) [Journal article]This study is described correlating the perfomance of engineering students in basically conceptual physics quizzes with their performance in physics exams constituted essentially by problem solving items. Research findings ... -
Hall effect in Ce 1-x Y x/Pd 3 mixed-valence alloys
(1985) [Journal article]Mixed-valence and Kondo lattice systems exhibit large anomalous Hall coefficients with a striking change of sign at low temperature in severa! systems (CePd3, CeCu6, ... , etc.). We have studied the Hall effect of Ce1-x ... -
Halo formation and emittance growth in the transport of spherically symmetric mismatched bunched beam
(2015) [Journal article]The effect of an initial envelope mismatch on the transport of bunched spherically symmetric beams is investigated. A particle-core model is used to estimate the maximum radius that halo particles can reach. The theory is ... -
Halo intruders in the Galactic bulge revealed by HST and Gaia : the globular clusters Terzan 10 and Djorgovski 1
(2019) [Journal article]Context. The low-latitude globular clusters Terzan 10 and Djorgovski 1 are projected in the Galactic bulge, in a Galactic region highly affected by extinction. A discrepancy of a factor of ∼2 exists in the literature in ... -
Hamiltonian formulation of QED in the superaxial gauge
(1982) [Journal article]We present a hamlltonian formulation of QED in a fully fixed axial gauge. The equal-time commutators for all field variables are computed and are shown to lead to the correct equations of motion. The constraints and gauge ... -
Hard and soft contributions in diffraction : a closed look
(2001) [Journal article]Disentangle the hard and soft dynamics in diffractive DIS is one of the main open questions of the strong interactions. We propose the study of the logarithmic slope in Q2 of the diffractive structure function as a potential ... -
Hard color-singlet exchange in dijet events in proton-proton collisions at √s = 13 TeV
(2021) [Journal article]Events where the two leading jets are separated by a pseudorapidity interval devoid of particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at √s=13 TeV. The signature is expected from ... -
Hard gluon evolution in warming medium
(2022) [Journal article]We describe the energy distribution of hard gluons travelling through a dense quark–gluon plasma whose temperature increases linearly with time, within a probabilis tic perturbative approach. The results were applied to ... -
Hardness and elasticity in cubic ruthenium dioxide
(2001) [Journal article]The Knoop hardness of the highly incompressible cubic phase of ruthenium dioxide was found to be 19–20 GPa from indentation tests. This value scales well with the shear modulus approximated by the elastic constant C44 of ... -
Hardness evaluation, stoichiometry and grain size of titanium nitride obtained with plasma nitriding on Ti-6AI-4V samples
(2010) [Journal article]Titanium nitride films were formed on the surface of Ti-6Al-4V discs by plasma nitriding (glow discharge) in different N2:H2 atmospheres at several substrate temperatures. In this study the influence of the process parameters ... -
Hardware-assisted thread and data mapping in hierarchical multi-core architectures
(2016) [Journal article]The performance and energy efficiency of modern architectures depend on memory locality, which can be improved by thread and data mappings considering the memory access behavior of parallel applications. In this paper, we ... -
Hardware-assisted visibility sorting for unstructured volume rendering
(2005) [Journal article]Harvesting the power of modern graphics hardware to solve the complex problem of real-time rendering of large unstructured meshes is a major research goal in the volume visualization community. While, for regular grids, ... -
