Today, at the Neutrino2018 conference in Heidelberg, the NOvA collaboration reported the first results from the antineutrino experiments, which indicate that muon antineutrinos oscillate into electron antineutrinos. This phenomenon is observed for the first time.
The NOvA neutrino experiment with a record large distance between the source and the detector is set in the Fermi National Accelerator Laboratory (Fermilab).The goal is to study neutrinos, the particles capable of passing through matter without any interaction with it.The long-term goal of the experiment is to find similarities and differences in how neutrinos and antineutrinos change from one type, muon neutrino in this case, to two other types, electron and tau neutrinos.The evidence for this transition of neutrinos and antineutrinos and their comparison will allow scientists to better understand how the Universe is constructed.
Manufacture of all parts for two professional inclinometers has been accomplished at the DLNP Workshop. The next stage is assembly and commissioning of the inclinometers at CERN. By the end of the year, the DLNP scientists will supply five of these new instruments to CERN and put them into operation. The work is carried out at the Department of Multiple Hadronic Processes under the leadership of Prof. J. Budagov within the JINR–CERN agreement and is aimed at stabilizing spatial positions of beams for increasing the LHC luminosity.
The high-precision instrument of the new generation, Precision Laser Inclinometer, makes it possible to monitor angular oscillations of the Earth in two orthogonal directions in the range of 10-6–4 Hz with a maximum sensitivity of 2.4∙10-11 rad/Hz1/2. It reliably detects angular inclinations of the Earth surface caused by the Moon, the Sun, distant (over 104 km away) earthquakes, the microseismic peak, and industrial sources.
Dmitri Semikoz (Directeur de Recherche CNRS, Paris) demonstrated that the standard static model of galactic cosmic rays suggested in 1990th came into conflict with a lot of modern experimental data, including variability measurements of the cosmic ray flux in the Galaxy, magnetic field measurements, and a great deal of anomalies in local observations of cosmic rays.
The year 2017 marked the 25th anniversary of the world’s largest scientific collaborations, the ATLAS collaboration, established in 1992 for carrying basic research at the Large Hadron Collider at CERN. JINR joined the preparations for the international ATLAS experiment as early as the preliminary R&D stage and became one of its main participants. The film is dedicated to this significant event.
On May 16, 2018, within the framework of the Dubna visit of Prof. K. Jakobs, spokesperson of the ATLAS experiment at the LHC, a meeting of the JINR participants in the ATLAS Collaboration was held.
The results and plans of physics research in the fields of the Standard Model, Higgs boson physics, search for new physics, and heavy quark physics were presented, and the prospects for the JINR participation in the operation of the facility and its upgrading during the upcoming technical shutdown were discussed. Also, readiness of JINR for manufacture of MicroMegas detectors was demonstrated to Prof. K. Jakobs.
ATLAS spokesperson Prof. K. Jakobs speaks about his seminar at DLNP on 16.05.2018, where he presented the results and further plans of research within the ATLAS project at the LHC.
