强子和核介质中的类介子超切伦科夫效应
Mesonic Super Čerenkov-like effects in hadronic and nuclear media
摘要：
研究了广义介子超切伦科夫辐射（SČR）.给出了低能π介子SCR扇区中π介子折射率的能量行为。我们估计，在某些核反应中，真正的相干SCR-π介子辐射主要可能在SCR-π介子能带190-315 MeV，910-960 MeV只对正π介子，80-1000 GeV对所有π介子。我们预言，当能量大于80 GeV时，SČR-π介子带将被展宽.证明了SCR-π介子发射角与（介子和射弹）能量之间的强相关性。给出了SCR π介子的谱分布，并估计了它们的极大值的位置。与现有的实验数据的协议进行了讨论。
英文摘要：
Generalized mesonic Super-Čerenkov Radiations (SČR) are investigated. The energy behavior of the pionic refractive index in the low energy pionic SCR-sector is presented. We estimated that the true coherent SCR-pion emission is possible mainly in the SCRS-energy bands 190-315 MeV for all pions; 910-960 MeV only for positive pions, and 80-1000 GeV for all pions, in certain nuclear reactions. We predicted that SČR-pionic band will be enlarged for the pion energies higher than 80 GeV. The strong correlations between angle of SCR-pion emission and (meson and projectile)-energies are evidentiated. The spectral distributions of the SCR-pions are presented and the position of their maxima are estimated. The agreement with the available experimental data is discussed.
