Sven Augustin, Carsten Müller

摘要:

本文研究了相对论质子束与强双色激光场碰撞产生正负电子对的非微扰机制。激光波是由一个强的低频和一个弱的高频模式,相互正交的偏振矢量。我们表明,高频场分量的存在下,可以大大提高对创建率。此外,高频模式的特征影响的角度和能量分布的创建粒子的演示,无论是在核静止框架和实验室框架。

英文摘要:

The nonperturbative regime of electron-positron pair creation by a relativistic proton beam colliding with a highly intense bichromatic laser field is studied. The laser wave is composed of a strong low-frequency and a weak high-frequency mode, with mutually orthogonal polarization vectors. We show that the presence of the high-frequency field component can strongly enhance the pair-creation rate. Besides, a characteristic influence of the high-frequency mode on the angular and energy distributions of the created particles is demonstrated, both in the nuclear rest frame and the laboratory frame.
