极强磁场对光子HBT干涉测量的影响

Effects of extremely strong magnetic field on photon HBT interferometry

Kazunori Itakura, Koichi Hattori

摘要:

我们讨论了光子的Hanbury Brown和Twiss(HBT)干涉术探测超相对论重离子碰撞产生的原始等离子体时空几何的潜在可达性。使HBT图像失真的一个可能效应是由于发射的光子与由外围碰撞中的碰撞重核引起的极强磁场之间的相互作用。我们研究了在强磁场中折射率变化的效应,称之为真空双折射。

英文摘要:

We discuss potential attainability by the Hanbury Brown and Twiss (HBT) interferometry of photons to probe the spacetime geometry of the primordial plasma created by ultrarelativistic heavy-ion collisions. A possible effect to distort the HBT image is due to an interaction between emitted photon and an extremely strong magnetic field induced by the colliding heavy nuclei in the peripheral collisions. We examine the effects of variation of the refraction index in the strong magnetic field that is called the vacuum birefringence.
