New Borexino results on measurement of solar neutrino fluxes were published in Natureon 25 October. Simultaneous spectral analysis of neutrino fluxes from the pp, Be-7, and pepreactions was performed for the first time. Unlike previous ones, this analysis was made in a wide energy range including three components of the solar neutrino spectrum.
The review lecture “Solar neutrinos” by D.V. Naumov is intended for a wide audience beginning with junior students.
The General Laboratory Seminar on the Modane Underground Laboratoryin the Fréjus Tunnel (France) was given by Fabrice Piquemal at DLNP on 29 October 2018.
Video abstract of the General Laboratory Seminar by Reham El-Kholy (Cairo University, Egypt), 24 October 2018
Reham El-Kholy (Cairo University, Egypt) speaks about a possibilityof studying production of antiprotons in the SPD detector at the NICAL collider for searching dark matter in astrophysical experiments.
Results of 10 years of the Borexino experiment: the most precise spectral analysis of solar neutrino fluxes
The international collaboration Вorexino published yesterday, on 24 October, in Nature the compendium of its results on neutrinos, accompanying the thermonuclear processes in the Sun.
The Borexino detector is ultrasensitive instrument constructed for the Solar neutrino studies. Detector registers neutrino from the Sun by scintillation light from the scattered off electrons in the liquid organic scintillator of the total mass of 300 tonnes. The concentration of radioactive elements in the central part of the detector is lower by a factor of 1010 compared to the typical ones in ordinary materials. The ultra-low level of radioactivity achieved in the detector is one of the milestones of the Borexino project success.
Professor Stepan Agaronovich Bunyatov, a talented scientist, outstanding organizer of science, doctor of science in physics and mathematics, passed away on 24 October 2018.
S.A. Bunyatov began working at the Laboratory of Nuclear Problems in February 1956.He defended the candidate of science dissertation in 1965and the doctoral dissertation in1977. In 1982, the title of professor was conferred on him.
His scientific interests lay in the fields of neutrino physics, charmed particle physics, interactions of π mesons and protons with nucleons and nuclei, πN→ππN reaction near the production threshold, and pion–pion interactions.
S.A. Bunyatov is a co-author of two discoveries, double π-meson charge exchange and production and decay of the nucleon-stable helium-8 nucleus, which were predicted by Ya.B. Zel’dovich.
General Laboratory Seminar by Dr. Bernhard Schwingenheuer (Max Planck Institute for Nuclear Physics, Heidelberg), 22 October 2018
Dr. Bernhard Schwingenheuer speaks about the current status and perspectives of the LNGS experiments on the search for neutrinoless double beta decay.
Yesterday, on 17 October 2018, winners of the Breakthrough Prize 2019 in Life Sciences, Fundamental Physics, and Mathematics were announced.The Breakthrough Prize 2019 in Fundamental Physics was awarded to Charles Kane and Eugene Mele from University of Pennsylvania “for new ideas about topology and symmetry in physics, leading to the prediction of a new class of materials that conduct electricity only on their surface.”
