Lecture “Neutrinos and black holes: space superheroes” at lyceum No. 6

On Monday, 23 December 2024, Dmitry Vadimovich Naumov held a lecture for fourth-graders “Neutrinos and black holes: space superheroes” at the invitation of Natalia Valeryevna Bovkunova, a teacher of junior classes at lyceum No. 6 named after Academician G. N. Flerov.

No significant evidence of the X17 boson found

In 2016, a group of researchers at the ATOMKI laboratories in Hungary reported an anomaly found in the relative angle distribution of the electron–positron pairs from the internal conversion of gamma rays from the 7Li(p,γ)8Be reaction. The anomaly was later confirmed in two additional processes, helium and carbon, and the so-found excess of events is compatible with the hypothesis of a new boson of mass 17 MeV/c2 — the X17 boson.

Congratulations to Maksim Sorokovikov on successful defence of the candidate dissertation!

Today, on 19 December 2024, Maksim Nikolaevich Sorokovikov has successfully defended his dissertation at the meeting of the Dissertation Council of DLNP JINR. The topic of his work was “Production of charmed particles in hadron-nucleus interactions at high energies in the phenomenological model of quark-gluon strings and calculation of atmospheric muon and neutrino fluxes”.

Status and Prospects of the JUNO Experiment

An important phase of the facility construction within the large-scale JUNO experiment with reactor electron antineutrinos comes to the end. Staff members of DLNP JINR together with the Chinese colleagues participate in assembly and preparation for launching of the JUNO detector.

Film devoted to the 75th anniversary of the Dzhelepov Laboratory of Nuclear Problems of JINR

Today, on 14 December, The Laboratory of Nuclear Problems of the Joint Institute for Nuclear Research is celebrating its 75th anniversary. The Group of Scientific Communication has prepared a film about the history of our laboratory.

Coherent interactions of fast proton with short-range NN correlations in nucleus

Leading scientists from the Laboratory of Theoretical Physics and the Laboratory of Nuclear Problems at JINR conducted research on coherent interactions of a fast proton with the short-range NN correlations in the nucleus, using data from the BM@N Experiment at the NICA Collider. An article presenting the results of the study was published in Physical Review C in June 2024. The authors are Alexey Larionov and Yuri Uzikov.

Novel Algorithm for Qualitative and Quantitative Material Analysis by the K-Edges for Photon-Counting Computed Tomography

Researchers of our laboratory Georgy Shelkov, Vladislav Rozhkov and Rostislav Sotenskii together with MSU scientists developed the algorithm for quantitative and qualitative material analysis by the K-edges for photon-counting computed tomography.
