论文摘要
研究了超递核相互作用的横截面的阈值行为。处理$ e^+e^ - $和$μ^+μ^ - $对以及$π^0 $和ParapoSitronium。提出了相应的能量阈值的值，并估计了新建的NICA和公平设施的这些过程的总横截面。
Threshold behavior of the cross sections of ultraperipheral nuclear interactions is studied. Production of $e^+e^-$ and $μ^+μ^-$ pairs as well as $π^0$ and parapositronium is treated. The values of corresponding energy thresholds are presented and the total cross sections of these processes at the newly constructed NICA and FAIR facilities are estimated.
