Yurina E.A. who is doing a Master’s degree in NEVOD centre has been awarded a medal of Russian Academy of Sciences and a prize for students in a nuclear physics competition in 2015 for her work “Energy-release of mu-meson groups in a water Cherenkov detector NEVOD”.

Russian Academy of Sciences has announced the results of 2015 competition for young scientists and students (“Poisk” newspaper, № 3 (1389), January 22, 2016). These competitions are held annually to support young researches in 19 main areas of natural, technical and humanitarian sciences. Yurina E.A. has been awarded a medal in nuclear physics.

She graduated fr om The N.G. Basov Higher School of Physicists and entered new NEVOD program “Physics of particles of high and extra high energies”.

She has done the work under the supervision of Kokoulin R.P. as a part of her Master’s program wh ere she researched energy-release of mu-meson groups in a water Cherenkov detector NEVOD. It’s the first time when energy-release of mu-meson groups is measured in an interval of a zenith angle 55°-85° and its growth is experimentally registered with the increase of the zenith angle. That’s how a new approach to mu-meson problem has been realized – an excess of mu-mesons in broad air showers under extra- und ultrahigh energies (10^15-10^19 eV) which isn’t explained by existing models of interaction even supposing iron structure of primary cosmic rays. This data is a good basis for dividing nuclear-physical and cosmo-physical reasons for the excess of mu-mesons.

All our congratulations, Ekaterina!
