Recent Developments in Neutrino/Antineutrino -Nucleus Interactions

Abstract Recent experimental results and developments in the theoretical treatment of neutrino-nucleus interactions in the energy range of 1-10 GeV are discussed. Difficulties in extracting neutrino-nucleon cross sections from neutrino-nucleus scattering data are explained and significance of understanding nuclear effects for neutrino oscillation experiments is stressed. Detailed discussions of the status of two-body current contribution in the kinematic region dominated by quasi-elastic scattering and specific features of partonic nuclear effects in weak DIS scattering are presented

Nuclear Shadowing in Electro-Weak Interactions

Shadowing is a quantum phenomenon leading to a non-additivity of electroweak cross sections on nucleons bound in a nucleus. It occurs due to destructive interference of amplitudes on different nucleons. Although the current experimental evidence for shadowing is dominated by charged-lepton nucleus scattering, studies of neutrino nucleus scattering have recently begun and revealed unexpected results.Comment: 77 pages, 57 figures.

La metamormosis de la universidad, homenaje a Edgar Morin

El mundo vive un cambio de época caracterizado por una crisis civilizatoria que afecta a la mayoría de las instituciones. La universidad no es ajena a este fenómeno. Cada vez más voces coinciden en que la educación convencional ha perdido aliento y vivacidad, por lo que se vuelve obligatorio replantear el quehacer educativo y reconfigurar sus propósitos. Esta obra promueve e impulsa maneras distintas de entender e implementar la universidad del siglo XXI. Encabezados por el gran pensador Edgar Morin, sus autores trazan el reto de generar una metamorfosis de la educación superior desde esquemas de complejidad y, para ello, ofrecen un conjunto de propuestas y experiencias sobre los caminos posibles para transformar las tareas universitarias. Dirigidas a académicos, sociólogos y todo aquel que tenga la preocupación intelectual de regenerar la organización de la universidad e, incluso, de la sociedad, estas páginas recuperan varias de las conferencias y tesis presentadas en el Seminario Internacional Universidad, pensar y actuar para la humanidad, en que Edgar Morin convoca a “resucitar la esperanza” y construir, desde la educación, un futuro nuevo, convirtiendo a esta obra en una invitación a continuar ahondando en la reflexión sobre las respuestas para cimentar un planeta más humano, más sustentable y más justo en que predomine, como indica el autor francés, el Eros sobre el Thanatos.ITESO, A.C

From Gargamelle to MINERvA: exploring the structure of the nucleon with neutrinos

Neutrino scattering experiments have been exploring the structure of the nucleon with Deep-Inelastic Scattering for over 50 years. Although hints of nucleon structure were available using CERN’s first neutrino beam in the 1960s, the study actually started quantitatively in the early 1970s with the Gargamelle heavy liquid bubble chamber that produced first neutrino confirmation of scaling. This study of nucleon structure continued with both bubble chambers and more massive electronic detectors that, with higher energy neutrino beams and $$Q^2$$ reach, examined the breaking of this scaling while testing Quantum Chromodynamics. A significant factor when including neutrino explorations of nucleon structure in the overall picture is that to gather significant statistics, neutrino experiments have had to use heavier nuclear targets. It has been experimentally demonstrated that the structure of the nucleon in the nuclear environment is indeed different than the free nucleon structure. Understanding this modified structure has played an important part in the experimental and theoretical exploration of nucleon structure by neutrinos and is one of the important goals of the on-going MINERvA experiment at Fermilab
