Commemorating the 110th Birthday of V. P. Dzhelepov. His Contribution to Science
- Details
- Category: Chronograph
V. P. Dzhelepov, the first director of the JINR Laboratory of Nuclear Problems, was not only a talented administrator but also a great scientist. He was fond of physics and knew which areas were worth focusing on. “Venedikt Petrovich had an exceptional intuition about what areas in science would become the main ones at this or that moment,” wrote academician S. S. Gernstein. Thanks to that intuition, the key directions of DLNP scientific activity were established, some of which are successfully evolving nowadays.
“B-Hadron Trigger in the ATLAS Experiment for Run 3” by Vladimir Lyubushkin
- Details
- Category: Seminars
The report gives a brief overview of the trigger system of the ATLAS experiment. The trigger tasks during Run 3 are discussed in detail in the light of actual problems of B-hadron physics. The quality of the experimental data collected during 2022 is discussed. (In connection with the election to fill the position of senior researcher.)
«AMBER Experiment at CERN» by Aleksey Guskov

Quantum chromodynamics (QCD) as a theory of interaction of quarks and gluons, is undoubtedly successful and gives a reliable description of the processes that take place in high-energy particle interactions. However, because of the large value of the strong interaction constant, QCD is not able to describe from its first principles the structure, properties and spectrum of systems built on the basis of the strong interaction - hadrons. This makes the experiment the only reliable source of such information.
International Collaboration FASER at CERN Detects First Neutrinos Made by Particle Collider
- Details
- Category: News
The FASER experiment has for the first time detected subatomic particles called neutrinos created by a particle collider. The discovery promises to deepen scientists’ understanding of the nature of neutrinos, first spotted in 1956, which are the most abundant particle in the cosmos and a key participant in the process that makes stars burn. The work could also shed light on cosmic neutrinos that travel large distances and collide with the Earth, providing a window on distant parts of the cosmos.
A Catalogue of All Detected and Simulated Events in the ATLAS Experiment at CERN Compiled
- Details
- Category: Новости науки
Annually, several billions of particle interactions are detected in the ATLAS experiment at the LHC at CERN. These events are processed, analyzed, and even larger simulated data samples are generated for them. To track the location of each event record and also to be able to search for and retrieve specific events during in-depth investigations, the ATLAS EventIndex catalogue has been compiled. The EventIndex project results have been recently published in a high-ranking scientific journal Computing and Software for Big Science.
