On the determination of the relative probability of $Υ (5 S) \to B_{s}^{()} B ˉ_{s}^{()}$ decays

A. E. Bondar, E. K. Karkaryan, A. A. Simovonian +1

Semileptonic decays of the $B B$ pairs produced in the $Υ (5 S)$ can be used to find the relative probability of $Υ (5 S) \to B_{s} B_{s}$ decay…

Revisiting the Problem of Positronium Moving Across a Magnetic Field

B. O. Kerbikov, A. A. Simovonian

Positronium spectrum and lifetimes are known with high precision. The situation is different for positronium moving across a magnetic field. The total momentum does not commute wit…
