“Bruno Pontecorvo is a man who is worth being a role model in what concerns not only work and love of physics but also the great variety of interests”
The DLNP Group of Scientific Communication asked Andrei Gridin about his work and plans for the upcoming year.
Please tell us a little bit about yourself: how long you have been working at DLNP JINR, which department you are working at, and what the scope of your scientific interests is.
I came to JINR in 2013, first as a laboratory assistant at the JINR University Centre, and later became a staff member of DLNP JINR. I started with tomographic reconstruction, and in 2014 I decided to engage in data analysis and joined the COMPASS experiment, in which I am still involved. Since 2023, our experiment has been continued under the name AMBER, and COMPASS has moved into the data analysis phase.
My work in the collaboration started with studying hadron collisions. Then I took part in studying exotic states of the charmonium. My current work is mostly connected with researching into the charmonium. I dedicated significant effort making a model of the experimental facility and conducting preliminary analysis of the data obtained.
Which of your scientific and professional achievements do you consider to be most significant?
My most important achievement is that I managed to analyse the physical data of the COMPASS collaboration from the very beginning till the very end. A series of publications on the study of intrinsic charm of the pion became the basis of my dissertation. This kind of work usually takes several years.
Who nominated you for the scholarship? What works were included in your application?
Aleksei Vyacheslavovich Guskov, the head of the Department of Colliding Beams and Deputy Director for Science of DLNP, nominated me for the scholarship. Works devoted to studying the intrinsic charm of the pion that were mostly performed by myself were presented in the application.
What scientific and professional plans do you have for the scholarship year?
I will continue studying hadron structure. At the end of the previous year our group suggested researching into the parton structure of kaons in the AMBER experiment. I also participate in the analysis of the data of the AMBER experiment on measuring the antiproton production cross section.
The results of this analysis are expected to allow raising the accuracy of predictions of natural antiproton flows in the galactic cosmic rays.
Apart from that, I take part in the NICA SPD project in which I simulate the process of proton-proton scattering and study the response of the facility under construction. Experience I gained at COMPASS was really helpful for me here.
Bruno Maksimovich Pontecorvo is one of the most eminent scientists who worked at the Joint Institute for Nuclear Research. What do his life, his contribution to world science and DLNP history mean to you?
For me Bruno Pontecorvo is a man who is worth being a role model in what concerns not only work and love of physics but also the great variety of interests. Bruno Maksimovich is a man who lived an interesting life. I am very glad that I am working in the Laboratory the founder of which was Bruno Pontecorvo.
