On May 22th, a seminar entitled "Decays of B-meson into dark matter particles" was held for the AANL researchers.

 

Alexander Khajamiryan talked about the recently developed B-Mesogenesis cosmological scenario predicting decays of heavy B mesons into a baryon and a hypothetical dark antibaryon. He presented and explained how to calculate the partial widths of these decays, using a method based on the light-cone sum rules in quantum chromodynamics. The speaker discussed the perspectives to detect these decays at the Belle-II experiment. The seminar was followed by active discussion with the audience.

 

This was the last seminar on dark particles concluding the series of lectures by Professor Alexander Khojamiryan started at AANL on May 16th, 2023.

 

Dr. Khojamiryan has graduated from Yerevan State University, Armenia. He worked at the AANL Center for Theoretical Physics, and here, in 1997, he defended his doctoral thesis on "Applications of CQD sum rules to heavy quarks and photons".

 

Dr. Khojamiryan is currently working at the Physics Department of the University of Siegen, teaching "Quantum Chromodynamics and Hadrons".
