重离子碰撞中的轫致辐射光子

Bremsstrahlung photons from stopping in heavy-ion collisions

Sohyun Park, Urs Achim Wiedemann

摘要:

我们研究了在欧洲核子研究中心大型强子对撞机(LHC)的超相对论核-核碰撞中,初始净电荷分布停止时产生的韧致辐射光子的光谱。这种效应至今还没有被发现,因为它只有在很低的横向动量和足够的前向速度时才变得相当大。我们认为,它可能是下一代大型强子对撞机重离子探测器ALICE-3,目前正在研究的范围内,我们评论的物理动机测量它。

英文摘要:

We examine the spectrum of bremsstrahlung photons that results from the stopping of the initial net charge distributions in ultrarelativistic nucleus-nucleus collisions at the CERN Large Hadron Collier (LHC). This effect has escaped detection so far since it becomes sizable only at very low transverse momentum and at sufficiently forward rapidity. We argue that it may be within reach of the next-generation LHC heavy-ion detector ALICE-3 that is currently under study, and we comment on the physics motivation for measuring it.
