相对论重离子碰撞中双电子俘获的双电子-正电子对产生

Double electron-positron pair production with two-electron capture in relativistic heavy-ion collisions

Melek Yilmaz Sengul

摘要:

我们计算了铅离子与铅离子碰撞过程中双电子俘获的双电子-正电子对产生的截面,并在LHC能区进行了计算。我们采用了类似的方法来计算束缚-自由电子-正电子对的产生。我们使用微扰理论和实施蒙特卡罗积分技术来计算最低阶费曼图。我们还比较了我们的双电子-正电子对的生产与文献中获得的双电子捕获截面的结果。这些计算可以帮助我们更多地了解强QED。

英文摘要:

We calculated the cross section of double electron-positron pair production with two-electron capture for the collisions of Pb+Pb ions and we did our calculations at LHC energies. We applied a similar methodology for the calculation of bound-free electron-positron pair production. We used perturbation theory and implemented Monte Carlo integration techniques to calculate the lowest order Feynman diagrams. We also compared our double electron-positron pair production with two-electron capture cross section results obtained in the literature. These calculations may help us to learn more about strong QED.
