标题： Enhancement of flow anisotropies due to magnetic field in relativistic heavy-ion collisions

摘要： 已知宇宙等离子体中存在背景磁场会扭曲宇宙微波背景辐射（CMBR）中的声波峰。这主要源于等离子体中不同类型的波，其速度取决于磁场与波矢之间的夹角。我们研究了这些效应在相对论重离子碰撞中的后果，在这些碰撞中，强磁场会在等离子体演化的早期阶段出现。我们表明，当由于导电流体中感应场较强而使磁场在整个早期阶段都保持强时，流系数可能会受到显著影响。特别是，磁场的存在会导致椭圆流系数$v_2$增强。 显示英文摘要

摘要： It is known that the presence of background magnetic field in cosmic plasma distorts the acoustic peaks in CMBR. This primarily results from different types of waves in the plasma with velocities depending on the angle between the magnetic field and the wave vector. We consider the consequences of these effects in relativistic heavy-ion collisions where very strong magnetic fields arise during early stages of the plasma evolution. We show that flow coefficients can be significantly affected by these effects when the magnetic field remains strong during early stages due to strong induced fields in the conducting plasma. In particular, the presence of magnetic field can lead to enhancement in the elliptic flow coefficient $v_2$.
