强场对未来直线对撞机相互作用点物理过程的影响

Strong field effects on physics processes at the Interaction Point of future linear colliders

A. Hartin, G. Moortgat-Pick, S. Porto

摘要:

未来的轻子对撞机将是精密的机器,其物理程序包括对希格斯扇区的仔细研究,并通过极化光束寻找新的物理学。这类机器的光度要求是在与强电磁场相互作用的点处必须有非常强的轻子束。这些强场不仅会导致束流辐射等明显的物理现象,而且还可能通过与束流场的虚交换影响粒子物理的各个过程。对于精密度研究,必须将强场效应理解为亚百分比水平。强外场效应可以通过毛茸茸的图片,或在一定的限制下,通过准经典算子方法来考虑。重要的理论发展正在进行中,这里我们概述了目前的状态。

英文摘要:

Future lepton colliders will be precision machines whose physics program includes close study of the Higgs sector and searches for new physics via polarised beams. The luminosity requirements of such machines entail very intense lepton bunches at the interaction point with associated strong electromagnetic fields. These strong fields not only lead to obvious phenomena such as beamstrahlung, but also potentially affect every particle physics process via virtual exchange with the bunch fields. For precision studies, strong field effects have to be understood to the sub-percent level. Strong external field effects can be taken into account exactly via the Furry Picture or, in certain limits, via the Quasi-classical Operator method . Significant theoretical development is in progress and here we outline the current state of play.
